NameDescription
System_CAPS_pubmethodCodeArgumentReferenceExpression()

Initializes a new instance of the CodeArgumentReferenceExpression class.

System_CAPS_pubmethodCodeArgumentReferenceExpression(String^)

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

NameDescription
System_CAPS_pubpropertyParameterName

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

System_CAPS_pubpropertyUserData

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

NameDescription
System_CAPS_pubmethodEquals(Object^)

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

System_CAPS_protmethodFinalize()

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

System_CAPS_pubmethodGetHashCode()

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

System_CAPS_pubmethodGetType()

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

System_CAPS_protmethodMemberwiseClone()

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

System_CAPS_pubmethodToString()

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 = gcnew CodeMemberMethod;
cmm->Parameters->Add( gcnew CodeParameterDeclarationExpression( "String","text" ) );
cmm->Name = "WriteString";
cmm->ReturnType = gcnew CodeTypeReference( "System::Void" );
array<CodeExpression^>^ce = {gcnew CodeArgumentReferenceExpression( "test1" )};

// Create a method invoke statement to output the string passed to the method.
CodeMethodInvokeExpression^ cmie = gcnew CodeMethodInvokeExpression( gcnew CodeTypeReferenceExpression( "Console" ),"WriteLine",ce );

// 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);
// }
