CodeArgumentReferenceExpression Class

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

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

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);
//        }                         

// Declare a method that accepts a string parameter named text.
CodeMemberMethod cmm = new CodeMemberMethod();
cmm.get_Parameters().Add(new CodeParameterDeclarationExpression("String",
    "text"));
cmm.set_Name("WriteString");
cmm.set_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 CodeExpression[] { new CodeArgumentReferenceExpression("text")});
// Add the method invoke expression to the method's statements collection.
cmm.get_Statements().Add(cmie);
// A VJ# code generator produces the following source code for
// the preceeding example code:        
//        private void WriteString(String text) 
//        {
//            Console.WriteLine(text);
//        } //WriteString
