List .Orderby 无法排序？？？

[baidu_26716013]

MyClass tmpClass = new MyClass();
List<MyClass> tmpList = new List<MyClass>();
tmpClass.MyID = "5";
tmpClass.RandomCode = "555";
tmpList.Add(tmpClass);

tmpClass = new MyClass();
tmpClass.MyID = "3";
tmpClass.RandomCode = "333";
tmpList.Add(tmpClass);

tmpClass = new MyClass();
tmpClass.MyID = "1";
tmpClass.RandomCode = "111";
tmpList.Add(tmpClass);

tmpClass = new MyClass();
tmpClass.MyID = "4";
tmpClass.RandomCode = "444";
tmpList.Add(tmpClass);

tmpClass = new MyClass();
tmpClass.MyID = "2";
tmpClass.RandomCode = "222";
tmpList.Add(tmpClass);

tmpList.OrderBy(p => p.MyID).ToList();

查看结果，排序还是 5 3 1 4 2 ?

我想把里面的 排序成 12345 请问不能排序是什么原因

[Forty2]

tmpList = tmpList.OrderBy(p => p.MyID).ToList();

tmpList = tmpList.OrderBy(p => p.MyID).ToList();

原来.....我以为跟 .add 一样直接执行了 谢谢你

引用 1 楼 Forty2 的回复:

tmpList = tmpList.OrderBy(p => p.MyID).ToList();

或tmpList.Sort((x,y)=>{ return x.MyID.CompareTo(y.MyID); });
