Code snippet: Auto complete for ArgumentNullException in Visual Studio

Question

I'm often writing a c# code that goes like this:

    void func(object myObject)
    {
        if (myObject == null)
        {
            throw new ArgumentNullException("myObject");
        }
        ...

How do I write an auto-complete in Visual Studio 2012 for that type of code, so that I don't have to keep typing this all the time?

Since there hasn't been an interest, I'm going to close on this question by posting my own solution. Putting following file into C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC#\Snippets\1033\Visual C#\ifn.snippet will do the trick:

<?xml version="1.0" encoding="utf-8" ?>
<CodeSnippets xmlns="http://schemas.microsoft.com/VisualStudio/2005/CodeSnippet">

        <Code Language="csharp"><![CDATA[if ($argument$ == null)
        {
                    throw new ArgumentException("$argument$");
        }$end$]]>
        </Code>
    </Snippet>
  </CodeSnippet>
</CodeSnippets>

I defined a ReSharper shortcut for this using the keywords "argnull" that auto-generates and guesses the parameter I want. It's about the same effect as your solution, I think, though you don't need to muck with XML or where to place files.

Here's an example of a ReSharper VB.NET approach:

if $VAR$ is nothing then
  throw new ArgumentNullException("$VAR$")
end if
