Walkthrough: Create a code snippet

You lot can create a code snippet with but a few steps. All you demand to practise is create an XML file, fill up in the appropriate elements, and add your lawmaking to it. You tin optionally brand use of replacement parameters and project references. Import the snippet to your Visual Studio installation by using the Import button in the Code Snippets Director (Tools > Lawmaking Snippets Director).

Snippet template

The post-obit XML is the basic snippet template:

<?xml                              version=                "i.0"                                            encoding=                "utf-8"              ?> <CodeSnippets              xmlns=                "http://schemas.microsoft.com/VisualStudio/2005/CodeSnippet"              >     <CodeSnippet              Format=                "ane.0.0"              >         <Header>             <Title></Championship>         </Header>         <Snippet>             <Code              Language=                "                "              >                              <![CDATA[                ]]>                            </Code>         </Snippet>     </CodeSnippet> </CodeSnippets>

Create a code snippet

1. Create a new XML file in Visual Studio and add the template shown above.

2. Fill in the title of the snippet in the Title element. Apply the title Square Root.

3. Make full in the language of the snippet in the Language attribute of the Lawmaking element. For C#, use CSharp, for Visual Bones, apply VB, and for C++, use CPP.

   [!TIP] To see all the available linguistic communication values, browse the Code element attributes department on the Code snippets schema reference page.

4. Add the snippet code in the CDATA section inside the Code element.

   For C#:

   <Lawmaking                  Linguistic communication=                    "CSharp"                  >                                      <![CDATA[double root = Math.Sqrt(16);]]>                                    </Code>

   Or for Visual Basic:

   <Code                  Language=                    "VB"                  >                                      <![CDATA[Dim root = Math.Sqrt(xvi)]]>                                    </Lawmaking>

   [!Notation] You tin can't specify how lines of code in the CDATA section of a code snippet should exist indented or formatted. Upon insertion, the language service formats the inserted code automatically.

5. Salve the snippet as SquareRoot.snippet (you can save it anywhere).

Import a lawmaking snippet

1. You lot tin can import a snippet to your Visual Studio installation by using the Code Snippets Manager. Open up it by choosing Tools > Code Snippets Managing director.

2. Click the Import button.

3. Go to the location where you lot saved the lawmaking snippet in the previous process, select it, and click Open.

4. The Import Code Snippet dialog opens, asking you to cull where to add together the snippet from the choices in the right pane. One of the choices should be My Code Snippets. Select it and click Finish, then OK.

5. The snippet is copied to one of the following locations, depending on the code language:

   ::: moniker range="vs-2017"

   %USERPROFILE%\Documents\Visual Studio 2017\Code Snippets\Visual C#\My Code Snippets %USERPROFILE%\Documents\Visual Studio 2017\Code Snippets\Visual Basic\My Code Snippets

   ::: moniker-end

   ::: moniker range=">=vs-2019"

   %USERPROFILE%\Documents\Visual Studio 2019\Code Snippets\Visual C#\My Lawmaking Snippets %USERPROFILE%\Documents\Visual Studio 2019\Code Snippets\Visual Bones\My Lawmaking Snippets

   ::: moniker-terminate

6. Examination your snippet by opening a C# or Visual Basic project. With a lawmaking file open in the editor, choose Snippets > Insert Snippet from the right-click menu, so My Code Snippets. You should see a snippet named Square Root. Double-click it.

   The snippet code is inserted in the code file.

Clarification and shortcut fields

::: moniker range="vs-2017"

1. Clarification fields give more information near your code snippet when viewed in the Code Snippets Manager. The shortcut is a tag that users can type in gild to insert your snippet. Edit the snippet you have added by opening the file %USERPROFILE%\Documents\Visual Studio 2017\Code Snippets\[Visual C# or Visual Basic]\My Code Snippet\SquareRoot.snippet.

::: moniker-end

::: moniker range=">=vs-2019"

1. Description fields give more information virtually your code snippet when viewed in the Lawmaking Snippets Manager. The shortcut is a tag that users can type in order to insert your snippet. Edit the snippet yous have added by opening the file %USERPROFILE%\Documents\Visual Studio 2019\Lawmaking Snippets\[Visual C# or Visual Basic]\My Code Snippet\SquareRoot.snippet.

::: moniker-end

[!TIP] Since you're editing the file in the directory where Visual Studio placed it, you don't need to reimport it to Visual Studio.

2. Add together Author and Clarification elements to the Header element, and make full them in.

3. The Header element should look something like this:

   <Header>     <Title>Square Root</Title>     <Author>Myself</Author>     <Description>Calculates the square root of xvi.</Description> </Header>

4. Open the Code Snippets Manager and select your code snippet. In the right pane, notice that the Description and Author fields are now populated.

   

5. To add a shortcut, add a Shortcut element within the Header element:

   <Header>    <Title>Foursquare Root</Title>    <Author>Myself</Author>    <Description>Calculates the square root of xvi.</Description>    <Shortcut>sqrt</Shortcut>  </Header>

6. Save the snippet file again.

7. To test the shortcut, open the project you used previously, type sqrt in the editor and press Tab (once for Visual Bones, twice for C#).

   The snippet code is inserted.

Replacement parameters

You may want parts of a lawmaking snippet to be replaced by the user. For example, you might want the user to replace a variable proper name with one in their electric current project. You can provide two types of replacements: literals and objects. Employ the Literal chemical element to identify a replacement for a piece of code that is entirely independent within the snippet merely volition likely be customized subsequently information technology's inserted into the code (for example, a string or numeric value). Employ the Object element to identify an item that's required past the code snippet simply is likely to be defined outside of the snippet itself (for example, an object instance or a command).

1. To enable the user to easily supersede the number to calculate the square root of, change the Snippet element of the SquareRoot.snippet file as follows:

   <Snippet>   <Code                  Language=                    "CSharp"                  >                                      <![CDATA[double root = Math.Sqrt($Number$);]]>                                    </Code>   <Declarations>     <Literal>       <ID>Number</ID>       <ToolTip>Choose the number y'all want the foursquare root of.</ToolTip>       <Default>16</Default>     </Literal>   </Declarations> </Snippet>

   Find that the literal replacement is given an ID (Number). That ID is referenced from within the lawmaking snippet by surrounding information technology with $ characters:

                                         <![CDATA[double root = Math.Sqrt($Number$);]]>                                  

2. Salve the snippet file.

3. Open a project and insert the snippet.

   The code snippet is inserted and the editable literal is highlighted for replacement. Hover over the replacement parameter to see the tooltip for the value.

   

   [!TIP] If in that location's more than one replaceable parameter in a snippet, you lot can press Tab to navigate from 1 to the other to change the values.

Import a namespace

Y'all tin apply a lawmaking snippet to add together a using directive (C#) or Imports statement (Visual Bones) by including the Imports element. For .NET Framework projects, you tin can too add a reference to the projection by using the References element.

The following XML shows a code snippet that uses the method File.Exists in the System.IO namespace and, therefore, defines the Imports element to import the System.IO namespace.

<?xml                              version=                "ane.0"                                            encoding=                "utf-viii"              ?> <CodeSnippets              xmlns=                "http://schemas.microsoft.com/VisualStudio/2005/CodeSnippet"              >   <CodeSnippet              Format=                "1.0.0"              >     <Header>       <Championship>File Exists</Title>       <Shortcut>exists</Shortcut>     </Header>     <Snippet>       <Code              Language=                "CSharp"              >                              <![CDATA[var exists = File.Exists("C:\\Temp\\Notes.txt");]]>                            </Code>       <Imports>         <Import>           <Namespace>System.IO</Namespace>         </Import>       </Imports>     </Snippet>   </CodeSnippet> </CodeSnippets>
