This example demonstrates using a CodeBaseReferenceExpression to reference a base class method.
// Example method invoke expression uses CodeBaseReferenceExpression to produce
// a base.Dispose method call
CodeMethodInvokeExpression^ methodInvokeExpression =
gcnew CodeMethodInvokeExpression( // Creates a method invoke expression
gcnew CodeBaseReferenceExpression, // targetObjectparameter can be a base class reference
"Dispose",gcnew array<CodeExpression^>{} ); // Method name and method parameter arguments
// A C# code generator produces the following source code for the preceeding example code:
// base.Dispose();
// Example method invoke expression uses CodeBaseReferenceExpression to produce
// a base.Dispose method call
CodeMethodInvokeExpression methodInvokeExpression =
// Creates a method invoke expression
new CodeMethodInvokeExpression(
// targetObject parameter can be a
// base class reference
new CodeBaseReferenceExpression(),
// Method name and method parameter arguments
"Dispose", new CodeExpression[] {});
// A C# code generator produces the following source code for the preceeding example code:
// base.Dispose();
' Example method invoke expression uses CodeBaseReferenceExpression to produce
' a base.Dispose method call
Dim methodInvokeExpression As New CodeMethodInvokeExpression( New CodeBaseReferenceExpression(), "Dispose", New CodeExpression() {})
' A Visual Basic code generator produces the following source code for the preceeding example code:
' MyBase.Dispose
CodeBaseReferenceExpression represents a reference to the base class of the current class. The base class is sometimes also known as the parent class or super class. References to the base class are commonly used when overriding a method or property in order to call the base class's implementation of that method or property. For example, an override of a ToString method that appends a string to the end of the base class's ToString
method would call base.ToString() in C#.
