public ref class CodeBaseReferenceExpression : CodeExpression

Constructors

	Name	Description
	CodeBaseReferenceExpression()	Initializes a new instance of the CodeBaseReferenceExpression class.

Properties

	Name	Description
	UserData	Gets the user-definable data for the current object.(Inherited from CodeObject.)

Methods

	Name	Description
	Equals(Object^)	Determines whether the specified object is equal to the current object.(Inherited from Object.)
	Finalize()	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)
	GetHashCode()	Serves as the default hash function. (Inherited from Object.)
	GetType()	Gets the Type of the current instance.(Inherited from Object.)
	MemberwiseClone()	Creates a shallow copy of the current Object.(Inherited from Object.)
	ToString()	Returns a string that represents the current object.(Inherited from Object.)

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#.

Examples

This example demonstrates using a CodeBaseReferenceExpression to reference a base class method.

C++

// 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();
