Original Readme

note

Coplt.Dropping

Auto gen dispose pattern

• Auto handle Dispose(bool dispoing) pattern
• Auto handle destructor/finalizer
• Allow multiple drops
• Specify the drop order [Drop(Order = X)]
• The first argument of Drop target method can be bool disposing
• Mark Drop directly on fields and properties (requires target type have Dispose method)
• Dose not supported AsyncDispose, too complicated, it is recommended to implement it manually
• Drop can mark on static methods, will pass this on first argument, if have bool disposing will be the second argument

Example

• Basic usage

  [Dropping]
  public partial class Foo1
  {
      [Drop]
      public void Drop()
      {
          Console.WriteLine(1);
      }
  }

  Generate output:

  Foo1.dropping.g.cs
