Make Method/Property Static refactoring

ReSharper | Refactor | Make Method Static…

To assign a shortcut, go to Tools | Options | Environment | Keyboard and find the ReSharper_MakeStatic command.

If the converted instance method uses instance members, ReSharper helps you add the necessary parameter representing this to apply these usages to. If the converted instance property uses instance members, the refactoring is not available.

In the example below, we use this refactoring to convert an instance method Merge of the Info class into a static method. After refactoring, usages of instance properties Id and Name are applied to the new parameter i1:

Before refactoring

class Info
{
  string Id { get; set; }
  string Name { get; set; }
  Info Merge(Info other)
  {
    return new Info
    {
      Id = Id + other.Id,
      Name = Name + other.Name
    };
  }
  void Test()
  {
    var i1 = new Info()
      { Id = "123", Name = "AA" };
    var i2 = new Info()
      { Id = "456", Name = "BB" };
    var merged = i1.Merge(i2);
  }
}

After refactoring

class Info
{
  string Id { get; set; }
  string Name { get; set; }
  static Info Merge(Info info, Info other)
  {
    return new Info
    {
      Id = info.Id + other.Id,
      Name = info.Name + other.Name
    };
  }
  void Test()
  {
    var i1 = new Info()
      { Id = "123", Name = "AA" };
    var i2 = new Info()
      { Id = "456", Name = "BB" };
    var merged = Merge(i1, i2);
  }
}
