Answer 1

This will be the simplest way,

if (System.IO.File.Exists(filePath)) 
{
  System.IO.File.Delete(filePath);
  System.Threading.Thread.Sleep(20);
}

Thread.sleep will help to work perfectly, otherwise, it will affect the next step if we doing copy or write the file.

Another way I did is,

if (System.IO.File.Exists(filePath))
{
System.GC.Collect();
System.GC.WaitForPendingFinalizers();
System.IO.File.Delete(filePath);
}
