GetLastError function from Kernel32.DLL. This method exists because it is not safe to make a direct platform invoke call to GetLastError to obtain this information.

The common language runtime can make internal calls to APIs that overwrite the GetLastError maintained by the operating system.exposes the Win32
You can use this method to obtain error codes only if you apply the System.Runtime.InteropServices.DllImportAttribute to the method signature and set the SetLastError field totrue. The process for this varies depending upon the source language used: C# and C++ are false by default, but the Declare statement in Visual Basic is true.
