让Dictionary key 支持自定义对象,则对象必须继承IEquatable,重写GetHashCode、Equals
class Foo : IEquatable<Foo> { public string Name { get; set;} public int FooID { get; set;} public override int GetHashCode() { return Name.GetHashCode()+FooID.GetHashCode(); } public override bool Equals(object obj) { return Equals(obj as Foo); } public bool Equals(Foo obj) { return obj != null && obj.FooID == this.FooID; } }
