Examples
This example demonstrates using a CodeThrowExceptionStatement to throw a new System.Exception
.
// This CodeThrowExceptionStatement throws a new System.Exception.
array<CodeExpression^>^temp0;
CodeThrowExceptionStatement^ throwException = gcnew CodeThrowExceptionStatement( gcnew CodeObjectCreateExpression( gcnew CodeTypeReference( System::Exception::typeid ),temp0 ) );
// A C# code generator produces the following source code for the preceeding example code:
// throw 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();
' This CodeThrowExceptionStatement throws a new System.Exception.
' The codeExpression parameter indicates the exception to throw.
' You must use an object create expression to new an exception here.
Dim throwException As New CodeThrowExceptionStatement( _
New CodeObjectCreateExpression( _
New CodeTypeReference(GetType(System.Exception)), _
New CodeExpression() {}))
' A Visual Basic code generator produces the following source code for the preceeding example code:
' Throw New System.Exception
Remarks
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.
