Hi,

If the msg id ends with 27. I need to delete the message ID from the list. How can I do it???


Thanks

推荐答案

List<string> s = new List<string>();
            s.RemoveAll( i => i.EndsWith("27"));

您还可以使用基于循环和索引的数组来删除项目.

you can also use for loop and index based array to remove item.

List<string> msgIds = new List<string>()
           {
               "CF00400","CFE6CEE","18F0010B","CFFB027"
           };
           int totalItems = msgIds.Count;
           for (int i = 0; i < totalItems; i++)
           {
               if (msgIds[i].Substring(msgIds[i].Length - 2, 2).Equals("27"))
               {
                   msgIds.Remove(msgIds[i]);
               }
           }
           foreach (var item in msgIds)
           {
               Response.Write(item + "<br/>");
           }

像这样尝试...

try like this...

List<string> lst = new List<string>();
       lst.Add("CF00400");
       lst.Add("CFE6CEE");
       lst.Add("18F0010B");
       lst.Add("CFFB027");

       lst = lst.Where(k => (!k.EndsWith("27"))).ToList();
