截取字符串然后再判断内中是否有大于50的值，如果有报错

截取字符串然后再判断其中是否有大于50的值，如果有报错
比如字符串是：‘2, ,12,31,27,54,0,,6,56,’
怎么做？就这么多分了，

[解决办法]

C# code

string str="2, ,12,31,27,54,0,,6,56,";String[] array=str.Split(new String[1]{","},StringSplitOptions.RemoveEmptyEntries);foreach(str s in array)  if(Convert.ToInt32(s)>50)  {    Console.WriteLine("大于50.")    Break;  }

C# code
static void Main(string[] args)        {            string str = "2, ,12,31,27,54,0,,6,56,";            String[] array = str.Split(new String[1] { "," }, StringSplitOptions.RemoveEmptyEntries);            List<int> arrayList = new List<int>();            foreach (string s in array)                if (s.Trim() != "")                    arrayList.Add(Convert.ToInt32(s));            //搜索数组中是否有大于50的数字，前面将字符串按逗号分隔            if (arrayList.Where(r => r > 50).Count() > 0)                Console.WriteLine("error");            Console.ReadLine();        }

C# code



static void Main(string[] args)
        {
            string str = "2, ,12,31,27,54,0,,6,56,";
            String[] array = str.Split(new String[1] { "," }, StringSplitOptions.Remove……

正则   \,((5[1-9])|(6-9)[\d])|([1-9][\d]{2,})\,  判断这个即可
[解决办法]
修正下上面的： \,[ ]*((5[1-9])|[6-9][\d])|([1-9][\d]{2,})[ ]*\,

C# code
string value = "2, ,12,31,27,50,0,,6,50,";MessageBox.Show(System.Text.RegularExpressions.Regex.IsMatch(value, "\\,[ ]*((5[1-9])|[6-9][\\d])|([1-9][\\d]{2,})[ ]*\\,", System.Text.RegularExpressions.RegexOptions.IgnoreCase));

bool have = "2, ,12,31,27,54,0,,6,56,".Split(',').Where(x => x.Trim() != "").Any(x => Convert.ToInt32(x) > 50);
