InvalidEnumArgumentException Class

This exception is thrown if you pass an invalid enumeration value to a method or when setting a property.

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 an InvalidEnumArgumentException exception and interpret its content. The example attempts to pass an invalid enumeration value (MessageBoxButtons) through casting, as the MessageBox.Show method's third argument. Upon catching the exception, the example fetches the respective error message, the invalid parameter, stack trace, and origin of the exception.

		try 
		{
		// Attempts to pass an invalid enum value (MessageBoxButtons) to the Show method
		    MessageBoxButtons myButton= (MessageBoxButtons) 123;
		    MessageBox.Show("This is a message","This is the Caption",myButton);
		}
		catch(InvalidEnumArgumentException invE) 
		{
		    Console.WriteLine(invE.Message);
		    Console.WriteLine(invE.ParamName);
		    Console.WriteLine(invE.StackTrace);
		    Console.WriteLine(invE.Source);
		}
