The finally block will be executed also for the return Statement(s) in between the code. But from my Point of view "Returns" in between the code is a usually bad Praxis.

Details you can find here:
try...catch...finally Statement[^]

It will execute the return statement - i.e. it will evaluate the parameter - and then it will execute the finally block. After that it will adjust the stack and return execution (along with the value) to the calling function.
If you aren't sure, then create some dummy code and test it:

C#

private void myButton_Click(object sender, EventArgs e)
    {
    Console.WriteLine("Before");
    Console.WriteLine(ShowMe());
    Console.WriteLine("After");
    }
private int ShowMe()
    {
    try
        {
        Console.WriteLine("Try");
        return ShowReturn();
        }
    finally
        {
        Console.WriteLine("Finally");
        }
    }
private int ShowReturn()
    {
    Console.WriteLine("ShowReturn");
    return 1;
    }

You will get:

Before
Try
ShowReturn
Finally
1
After

Which shows the order quite nicely.
