There's a way to create a code snippet with automatically create a using reference?

问题

I created a simple code snippet in c# which add the line

Debug.WriteLine("");

now the next step would be, when you use the snippet, to autocreate

using System.Diagnostic;

is there any way to automatically create the reference? I tried and set the snippets Reference and Import elements this way:

<Snippet>
  <References>
    <Reference>
      <Assembly>System.dll</Assembly>
    </Reference>
  </References>
  <Imports>
    <Import>
      <Namespace>System.Diagnostic</Namespace>
    </Import>
  </Imports>
      .
      .
      .
</Snippet>

but it doesn't work

回答1:

Unfortunately, Import only works for VB projects. It is explained on MSDN.

A little late to the game, but this does work for C# now :)

<References>
    <Reference>
        <Assembly>System.dll</Assembly>
    </Reference>
</References>
<Imports>
    <Import>
       <Namespace>System.Diagnostic</Namespace>
    </Import>
</Imports>

Place those inside the <Snippet> section. The docs even mention (This works for C# as well.).

https://docs.microsoft.com/en-us/visualstudio/ide/walkthrough-creating-a-code-snippet?view=vs-2017#add-references-and-imports

PS: if you want to add more than one import, do it like this:

<Imports>
    <Import>
        <Namespace>System.Diagnostic</Namespace>
    </Import>
    <Import>
        <Namespace>System.Reflection</Namespace>
    </Import>
</Imports>

System.Diagnostics.Debug.WriteLine("");

Instead of inserting a reference you could use the fully qualified name in your snippet.

I had a look at the mbox snippet created by microsoft and came up with the following:

<?xml version="1.0" encoding="utf-8"?>

   <CodeSnippet Format="1.0.0">

     </Header>
     <Snippet>    
       <Declarations>
         <Literal>

       </Declarations>
       <Code Language="csharp"><![CDATA[$SystemDiagnosticsDebugWriteLine$.WriteLine($string$);$end$]]></Code>
     </Snippet>
  </CodeSnippet>
</CodeSnippets>
