Passing arguments to a method using CodeDOM

Question

User-135741485 posted
I'm trying to pass arguments by ref to a method using codedom and I could not find how to do this. If I use: CodeParameterDeclarationExpression, it shows ref void next to the argument and I could not find Direction property in CodeArgumentReferenceExpression.

Any help to solve this is appreciated.

I figured out the solution for this. I should be using CodeDirectionExpression. Here's how it is done.

// Declares a parameter passed by reference using a CodeDirectionExpression. CodeDirectionExpression param1 = new CodeDirectionExpression(FieldDirection.Ref, new CodeFieldReferenceExpression( new CodeThisReferenceExpression(), "TestParameter" )); // Invokes a method on this named TestMethod using the direction expression as a parameter. CodeMethodInvokeExpression methodInvoke1 = new CodeMethodInvokeExpression(new CodeThisReferenceExpression(), "TestMethod", param1 ); // A C# code generator produces the following source code for the preceeding example code:    //        this.TestMethod(ref TestParameter);
