Linq查找

[nikolaichow]

List<string> list=new List<string>();

我现在想查询某一个值是否在list中存在，忽略大小写，请问如何使用linq?

List<string> list = new List<string>(); var vs = list.Where(v => v==你的值); 判断vs的count是否大于0

[狼烟辉]

var count = list.Where(data => data.Contains("11")).ToList().Count;

[莱昂纳多达芬奇]

bool exist = list.Where(item => item.ToUpper().Equals(你的值.ToUpper())).Any();

[莱昂纳多达芬奇]

bool exist = list.Any(item => item.ToUpper().Equals(你的值.ToUpper()));

[EnForGrass]

  string Findstr = "dd";
            List<string> plist = new List<string>() { "22", "dd", "444" };
            bool IsContain = plist.Where(s => s.ToLower().Contains(Findstr.ToLower())).Any();

楼上正解！！！把参数和list元素都统一成大写或小写就行了！
