The HttpException class is an HTTP-specific exception class that enables ASP.NET to generate exception information. For more information about throwing and handling exceptions, see Handling and Throwing Exceptions.

The following code example demonstrates how to use the HttpException class to raise customized exceptions. The Button_Click method determines which button was clicked, and then calls either the CheckNumber or CheckBoolean method. If the user-entered value in the text box does not correspond to the expected type, an HttpException exception is created and thrown with a customized message based on the error type.

Security noteSecurity Note:

This example has a text box that accepts user input, which is a potential security threat. By default, ASP.NET Web pages validate that user input does not include script or HTML elements. For more information, see Script Exploits Overview (Visual Studio).
