You have to use COM interop because user32 is unmanaged code that means written outside the .Net language C, C++(not VC++) so we use the System.Runtime.InteropServices to import this unmanaged code
First add the namespace System.Runtime.Interop
Then to call any function within user32.dll library you have to do as follow
[DllImport("user32.dll")]
static extern
then to call it you simply invoke it within your code
Example:
To draw text using the method DrawText of user32.dll
