c# - 如何从字符串中删除字符的确切出现？

Question

例如，我有一个像这样的字符串:

string str = "santhosh,phani,ravi,phani123,praveen,sathish,prakash";

我想从 str 中删除字符 ,phani。

现在，我正在使用 str = str.Replace(",phani", string.Empty);

然后我的输出是:str="santhosh,ravi123,praveen,sathish,prakash";

但我想要这样的输出:str="santhosh,ravi,phani123,praveen,sathish,prakash";

Answer 1

string str = "santhosh,phani,ravi,phani123,praveen,sathish,prakash";
var words = str.Split(',');
str = String.Join(",", words.Where(word => word != "phani"));
