How to get C# Assembly GUID using Reflection

assembly.GetCustomAttributes(typeof(System.Runtime.InteropServices.GuidAttribute), false);

Is this a joke or what? You CANNOT use GetExecutingAssembly() from an instance, and you can't use string return type for a void method!

No joke, it's typo. Now everything is ok. Thanks for your comment.

"you CANNOT use GetExecutingAssembly()"

Why not?

I'm using GetExecutingAssembly in my code and it works fine...

as in: Assembly.GetExecutingAssembly().GetName().Version.ToString();

cartoon, Assembly is class not an instance. dumb

But 'GetExecutingAssembly()' gets the assembly representing the assembly that contains the code that is currently executing... yeah, really dumb...

Solution:

public string AssemblyGuidString()
{
object[] arr = System.Reflection.Assembly.GetExecutingAssembly().GetCustomAttributes(typeof(System.Runtime.InteropServices.GuidAttribute), false);

if (arr.Length > 0)
{
return ((System.Runtime.InteropServices.GuidAttribute)arr[0]).Value;
}
else
{
return String.Empty;
}
}
