我如何从数组中删除任何字符串,而只有整数
string[] result = col["uncheckedFoods"].Split(',');
我有
[0] = on; // remove this string [1] = 22; [2] = 23; [3] = off; // remove this string [4] = 24;
我想要
[0] = 22; [1] = 23; [2] = 24;
我试过了
var commaSepratedID = string.Join(",",result);
var data = Regex.Replace(commaSepratedID,"[^,0-9]+",string.Empty);
解决方法
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();
