Like this:

string strTemp = new string('\0', 255);

The '\0' part is the equivalent of the the Chr(0) function (ascii character NUL).

Btw, I assume you meant this as VB code, because the mentioned VB code will not compile (first parameter of constructor cannot be an Integer):

Dim strTemp As New String(Chr(0), 255)


next code is:

lRet = GetTempPath(255, strTemp)

API function for the GetTempPath is declared like this:

Private Declare Function GetTempPath Lib "Kernel32" Alias "GetTempPathA" (ByVal nBufferLength As Long, ByVal lpBuffer As String) As Long

How will I convert this into C#.

You don't need API functions old style anymore in .NET. You can use the .NET library functions, which are type safe. In this case:


If you do not want the "System.IO" in front of it, you can put that in the using headers:

using System.IO;

string strTemp = Path.GetTempPath();

As you can see, you do not need to initialize your variables with nullpadded strings anymore. Quite handy this way, isn't it? And whether you use VB.NET or C#.NET or any other .NET language, you can always use these base libraries.

Not the solution you were looking for? Getting a personalized solution is easy.
