我有一个字符串列表,其中包含一些带有特殊字符(例如-,[,],(,)的字符串).
I have a list of string that contains few strings with some special characters like -, [, ], (, ).
我正在将字符串传递给需要解析以上列表和方法的方法.查找是否找到完全匹配的内容.
I am passing a string to a method where I need to parse the above list & find if the exact match is found or not.
为此,我编写了以下代码,但是当字符串中出现特殊字符时,就无法进行比较.
For this I have written the below code, but when ever the special characters are present in the string, its not able to compare.
foreach (var item in myList) { if (myInput.Trim().ToUpper() == item.Trim().ToUpper() ) //Here myInput is "In - Com [SP]" { count++; } }但是,如果我通过前面的@符号比较静态字符串,则比较工作正常.例如:
But if I compare a static string by a preceding @ symbol, then the compare is working fine. For Example :
if (item == @"In - Com [SP]") { count++; }有人可以帮助我如何将其合并为动态字符串列表吗?注意:我们不能将@与字符串变量连接.
Can anyone please help me how to incorporate this for a dynamic list of strings? NB : We cant concatenate @ with a string variable.
使用Regex存在任何方式吗?
Any ways exist by using Regex?
推荐答案如果要计数,只需 Count()借助 Linq 即可;要测试字符串是否相等,请使用 String.Equals :
If you want to count, just Count() with a help of Linq; to test if strings are equal use String.Equals:
System.Linq; ... // do not do Trim() repeatedly String testValue = myInput.Trim(); int count = myList .Count(item => String.Equals(item.Trim(), testValue, StringComparison.OrdinalIgnoreCase));更多推荐
