c# string数组转换为int数组

 var arrStr=ReceiveUsers.Split(new char[]{',','，'},StringSplitOptions.RemoveEmptyEntries);
//C# 3.0下用此句
var arrInt=  Array.ConvertAll<string, int>(arrStr, s => int.Parse(s));
//C# 2.0下用此句
var arrInt= Array.ConvertAll<string, int>(arrStr, delegate (string s) { return int.Parse(s); } );
