How can I reverse code around an equal sign in Visual Studio?

Question

After writing code to populate textboxes from an object, such as:

txtFirstName.Text = customer.FirstName;
txtLastName.Text = customer.LastName;
txtAddress.Text = customer.Address;
txtCity.Text = customer.City;

is there way in Visual Studio (or even something like Resharper) to copy and paste this code into a save function and reverse the code around the equal sign, so that it will look like:

customer.FirstName = txtFirstName.Text;
customer.LastName = txtLastName.Text;
customer.Address = txtAddress.Text;
customer.City = txtCity.Text;

Answer 1

None that I know of. Of course, if you use one of the many binding approaches available, then you won't have to - the binding will do the update in both directions (including change via notifications).

So for winforms:

txtFirstName.DataBindings.Add("Text", customer, "FirstName");

etc

Answer 2

• Copy and paste the original block of code
• Select it again in the place you want to switch
• Press Ctrl-H to get the "Replace" box up
• Under "Find what" put: {[a-zA-Z\.]*} = {[a-zA-Z\.]*};
• Under "Replace with" put: \2 = \1;
• Look in: "Selection"
• Use: "Regular expressions"
• Hit Replace All

An option to get them in there that way in the first place with Resharper would be to define a live template similar to:

$uiElement$ = $dto$;
$dto$ = $uiElement$;

This will allow you to type them once and it will duplicate it for you and then you can cut and paste the save version to the other method.
