Equivalent of VB string declaration...

I am familiar with declaring string variables and such. However I've got this one problem, and it comes down to the need for an exactly equivalent C# statement to this:

VB Code:

Dim sString As String * 30

I'm not too sure what it does, but it's what I need to do. I've already tried creating a string, length of 30, containing white space but what I think it wants is a string, length 30, containing nothing at all, not even white spaces.

Fixed length strings are not supported anymore.

Ah bollocks! OK, here's the exact content (in C#), you're moderator on .NET so you're probably a god when it comes to it:

VB Code:

public static string GetNumberOfTracks(string Alias)
{
string sResult = new string(' ', 30);
mciSendString("status " + Alias + " number of tracks wait", sResult, 30, null);
return sResult;
}

So you don't have to look it up:
Here's the article on MSDN...

The function definitely works because I'm using it for lots of other working stuff, I just can't get it to return things...

Any help is *greatly* appreciated:) :) :)
