How can I determine the subsystem used by a given .NET assembly?

Question

In a C# application, I\'d like to determine whether another .NET application is a Console application or not.

Can this be done using the reflection APIs?

The SHGetFileInfo function can do this:

[DllImport("shell32.dll", CharSet=CharSet.Auto, EntryPoint="SHGetFileInfo")]
public static extern ExeType GetExeType(string pszPath, uint dwFileAttributes = 0, IntPtr psfi = default(IntPtr), uint cbFileInfo = 0, uint uFlags = 0x2000);

[Flags]
public enum ExeType
{
    None = 0,
    WinNT = 0x04000000,
    PE = ((int)'P') | ((int)'E' << 8),
    NE = ((int)'N') | ((int)'E' << 8),
    MZ = ((int)'M') | ((int)'Z' << 8),
}

Then, according to the specification, if it's only MZ or PE, it is opened in console, otherwise (if a version is specified), it is open in a window.

ExeType type = GetExeType("program.exe");
if(type == ExeType.PE || type == ExeType.MZ) return "console";
else return "window";
