How to: Promote Local Variable to Parameter

Use this procedure to perform the Promote Local Variable to Parameter refactoring operation. For more information, see Promote Local Variable to Parameter.

To promote a local variable to parameter

1. Create a console application, and set it up as described in the following example. For more information, see How to: Create a C# Console Application.

2. Place the pointer next to i at its definition in MethodB.

3. From the Refactor menu, select Promote Local Variable to Parameter.

   You can also type the keyboard shortcut CTRL+R, P to complete the refactoring operation.

   You can also right-click the pointer, point to Refactor on the context menu, and then click Promote Local Variable to Parameter to complete the refactoring operation.

   The MethodB should now have a parameter int i, and the call ProtoA.MethodB will now pass zero as a value.

Example

To set up this example, create a console application named PromoteLocal, and then add the following code after the Program class in the PromoteLocal namespace. For more information, see How to: Create a C# Console Application.

    class ProtoA
    {
        public static void MethodB()
        {
            // Invoke on 'i'
            int i = 0;
        }
    }

    class ProtoC
    {
        void MethodD()
        {
            ProtoA.MethodB();
        }
    }
