C# 对象类型集合自定义排序

对象类型集合自定义排序：

对象类型：

class Model
{public string id{get;set;}public string name{get;set;}
}List<Model> lst = new List<Model>(){new Model(){"1","aa"},new Model(){"2","bb"},new Model(){"3","cc"},new Model(){"4","dd"},
};

自定义的顺序列表：

string[] orderArr = new string[]{"bb","cc","dd"};

排序方法：

var orderElements = lst.OrderBy(o => {int index = 0;index = Array.IndexOf(orderArr,o.name);if (index != -1){return index;}else{return int.MaxValue;}});

结果orderElements顺序为：

bb,cc,dd,aa
