c# 从数组中删除字符串

Question

我如何从数组中删除任何字符串并只使用整数

string[] result = col["uncheckedFoods"].Split(',');

我有

[0] = on;      // remove this string
[1] = 22;
[2] = 23;
[3] = off;      // remove this string
[4] = 24;

我要

[0] = 22;
[1] = 23;
[2] = 24;

我试过了

var commaSepratedID = string.Join(",", result);

var data = Regex.Replace(commaSepratedID, "[^,0-9]+", string.Empty);

但是第一个元素之前有一个逗号，有没有更好的方法来删除字符串？

Answer 1

这将选择所有可以解析为 int

的字符串

string[] result = new string[5];
result[0] = "on";      // remove this string
result[1] = "22";
result[2] = "23";
result[3] = "off";      // remove this string
result[4] = "24";
int temp;
result = result.Where(x => int.TryParse(x, out temp)).ToArray();
