List<string>字符串转Int数组
先转数组，再转类型

[C#] 纯文本查看 复制代码

List<string> strList = new List<string>();
strList.AddRange(new string[] { "9", "4", "7" });
int[] list = Array.ConvertAll<string, int>(strList.ToArray(), s => int.Parse(s));

或者先转类型，再转数组

[C#] 纯文本查看 复制代码

List<string> strList = new List<string>();
strList.AddRange(new string[] { "9", "4", "7" });
int[] intList = strList.Select(s => int.Parse(s)).ToArray();
