Extract Method refactoring

This refactoring allows you to create a new method or a local function based on the selected code fragment. ReSharper for Visual Studio Code analyzes the selected statements and detects variables that can be converted into method parameters or represent its return value.

Consider the following example. The method PrintReversed() actually does two things: it reverses the string and prints it. We can select the reversing logic, which is all statements except Console.WriteLine(reversed);, and use this refactoring to move that logic to a new method.

            
static void PrintReversed(string input)
{
  var chars = input.ToCharArray();
  Array.Reverse(chars);
  var reversed =  new string(chars);
  Console.WriteLine(reversed);
}

        

            
static void PrintReversed(string input)
{
  var reversed = ReverseStr(input);
  Console.WriteLine(reversed);
}

private static string ReverseStr(string input)
{
  var chars = input.ToCharArray();
  Array.Reverse(chars);
  var reversed = new string(chars);
  return reversed;
}
