CodeThrowExceptionStatement can represent a statement that throws an exception. The expression should be, or evaluate to, a reference to an instance of a type that derives from the Exception class.

The ToThrow property specifies the exception to throw.

This example demonstrates using a CodeThrowExceptionStatement to throw a new System.Exception.

// This CodeThrowExceptionStatement throws a new System.Exception.
CodeThrowExceptionStatement throwException = new CodeThrowExceptionStatement( 
    // codeExpression parameter indicates the exception to throw. 
    // You must use an object create expression to new an exception here. 
    new CodeObjectCreateExpression(
    // createType parameter inidicates the type of object to create. 
    new CodeTypeReference(typeof(System.Exception)),
    // parameters parameter indicates the constructor parameters. 
    new CodeExpression[] {} ) );

// A C# code generator produces the following source code for the preceeding example code: 

// throw new System.Exception();
