Tips & Tricks:
If you want to use GetModuleFilename to retrieve the path the current executable was started from, you should instead consider using System.Windows.Forms.Application.StartupPath. This is a wrapper around GetModuleFilename, so it probably does exactly what you want.
Another way: Process.GetCurrentProcess().MainModule.FileName
Sample Code:
using System;
using System.Text;
using System.Runtime.InteropServices;
using Library.Win32.Process;
namespace Test
{
class Class1
{
[STAThread]
static void Main(string[] args)
{
StringBuilder fileName = new StringBuilder(255);
DllFuntions.GetModuleFileName(IntPtr.Zero, fileName, fileName.Capacity);
Console.WriteLine(fileName);
}
}
}
Alternative Managed API:
System.Diagnostics.ProcessModule.FileName or System.Reflection.Module.FullyQualifiedName.
