Win32Exception Class

Win32 error codes are translated from their numeric representations into a system message when they are displayed. Use NativeErrorCode to access the numeric representation of the error code associated with this exception. For more information about the error codes, see "Win32 Error Codes" in the Platform SDK documentation at http://msdn.microsoft.com.

Note

The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: SharedState. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.

The following code example shows how to catch a Win32 exception and interpret its content. The example attempts to start a nonexistent executable, which results in a Win32 exception. Upon catching the exception, the example fetches the respective error message, code, and origin of the exception.

	    try {
		System.Diagnostics.Process myProc = new System.Diagnostics.Process();
		myProc.StartInfo.FileName = "c:\nonexist.exe";  //Attempting to start a non-existing executable
		myProc.Start();    //Start the application and assign it to the process component.    
	    }
  	    catch(Win32Exception w) {
		Console.WriteLine(w.Message);
		Console.WriteLine(w.ErrorCode.ToString());
		Console.WriteLine(w.NativeErrorCode.ToString());
		Console.WriteLine(w.StackTrace);
		Console.WriteLine(w.Source);
		Exception e=w.GetBaseException();
		Console.WriteLine(e.Message);
 	    }
