CodeArgumentReferenceExpression Class

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

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); 
//        }
