This class encapsulates an exception that is thrown to wrap the failure of a Win32 native method call. The NativeErrorCode property can retrieve the underlying Win32 error code that caused the exception to be thrown.

public class Win32Exception : System.Runtime.InteropServices.ExternalException {
// Public Constructors
   public Win32Exception();
   public Win32Exception(int error);
   public Win32Exception(int error, string message);
// Protected Constructors
   protected Win32Exception(System.Runtime.Serialization.SerializationInfo info, 
        System.Runtime.Serialization.StreamingContext context);
// Public Instance Properties
   public int NativeErrorCode{get; }
// Public Instance Methods
   public override void GetObjectData(System.Runtime.Serialization.SerializationInfo info,  
        System.Runtime.Serialization.StreamingContext context);  // overrides Exception
}
