Code inspection: Convert 'if do while' into 'while'

This inspection reports an if statement that only guards a do ... while loop with the same condition.

That pattern is equivalent to a while loop and is usually harder to read because the same condition is written twice.

Example

                while (true)
                {
                    if (count > 0)
                    {
                        do
                        {
                            count--;
                        } while (count > 0);
                    }
                }
            

                while (true)
                {
                    while (count > 0)
                    {
                        count--;
                    }
                }
            

Quick-fix

The quick-fix converts the if + do ... while construct into a single while loop.
