HttpException Constructor (Int32, String, Int32)

Initializes a new instance of the HttpException class using an HTTP response status code, an error message, and an exception code.

Namespace:  System.Web
Assembly:  System.Web (in System.Web.dll)

public HttpException(
	int httpCode,
	string message,
	int hr


Type: System.Int32
The HTTP response status code displayed on the client.
Type: System.String
The error message displayed to the client when the exception is thrown.
Type: System.Int32
The exception code that defines the error.

The following code example demonstrates the HttpException constructor of the HttpException class. The user name and e-mail information are entered by the user in the provided text boxes. If any of the text boxes are left blank, an HttpException object is created and thrown. The error code of the HttpException is obtained by the GetHttpCode method and displayed on the Web page.

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.
