C# Should I Loop until no exception?

Question

I want to go once through a loop but only if an exception is thrown go back through the loop. How would I write this in C#?

Thanks

What about the following where you can set a retry count:

            int tryCount = 0;

            while (tryCount < 3)
            {
                try
                {
                    someReturn = SomeFunction(someParams);
                }
                catch (Exception)
                {
                    tryCount++; 
                    continue;
                }
                break; 
            }

This smells of bad design to me. The general rule is: exceptions should not be used for flow control. There are a number of reasons for this; namely, there are usually better/more reliable methods that can be used to check things before an exceptions is thrown, and also it decreases efficiency.

Nonetheless, just for the sake of argument, you could do something like the following:

while (true)
{
    try
    {
        // do stuff here
    }
    catch (MyException)
    {
        continue;
    }

    // all is good
    break;
}

Again - this is not the recommended way. I would be happy to suggest something better if you could provide a bit more context/examples/
