Tips & Tricks:

Use Environment.ExpandEnvironmentVariables(path)

Sample Code:

string resourcePath = "\System32\shell32.dll,-4123";

resourcePath = Environment.ExpandEnvironmentVariables(resourcePath);

StringBuilder outBuff = new StringBuilder();

int result = SHLoadIndirectString(resourcePath, outBuff, -1, IntPtr.Zero);

//SHLoadIndirectString returns S_OK (0) if successfull

if(result == 0)

    Console.WriteLine(outBuff.ToString());
