如何从 C# 中的字符串数组中删除项目？

Question

I have an array of string . I want to remove an item from string. HOw i can do this.

string []values = User.Split(';');

Suppose values contains "1","2","3","4"

I want to delete or remove item "2" from values. How i can do this. Is there built in function in C#

Answer 1

Array is immutable object. So, you can't remove from array. You can create new array without this value using LINQ :

values = values.Where(o=> o != "2").ToArray();

Or, you can create List and remove from list:

List<string> values = User.Split(';').ToList();
values.Remove("2");

Answer 2

尝试这个：

myArray = myArray.Where(w => w != myArray[2]).ToArray();
