The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Represents a reference to the value of an argument passed to a method.

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


public class CodeArgumentReferenceExpression : CodeExpression


Initializes a new instance of the CodeArgumentReferenceExpression class.


Initializes a new instance of the CodeArgumentReferenceExpression class using the specified parameter name.


Gets or sets the name of the parameter this expression references.


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


Determines whether the specified object is equal to the current object.(Inherited from Object.)


Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)


Serves as the default hash function. (Inherited from Object.)


Gets the Type of the current instance.(Inherited from Object.)


Creates a shallow copy of the current Object.(Inherited from Object.)


Returns a string that represents the current object.(Inherited from Object.)

CodeArgumentReferenceExpression can be used in a method to reference the value of a parameter that has been passed to the method.

The ParameterName property specifies the name of the parameter to reference.

The following example code defines a method that invokes Console.WriteLine to output the string parameter passed to the method. A CodeArgumentReferenceExpression references the argument passed to the method by method parameter name.

// Declare a method that accepts a string parameter named text.
CodeMemberMethod cmm = new CodeMemberMethod();
cmm.Parameters.Add( new CodeParameterDeclarationExpression("String", "text") );
cmm.Name = "WriteString";
cmm.ReturnType = new CodeTypeReference("System.Void");        

// Create a method invoke statement to output the string passed to the method.
CodeMethodInvokeExpression cmie = new CodeMethodInvokeExpression( new CodeTypeReferenceExpression("Console"), "WriteLine", new CodeArgumentReferenceExpression("text") );

// Add the method invoke expression to the method's statements collection.
cmm.Statements.Add( cmie );

// A C# code generator produces the following source code for the preceeding example code:        
//        private void WriteString(String text) 
//        {
//            Console.WriteLine(text);
//        }
