判断字符串中是不是有数字

判断字符串中是否有数字
判断字符串中是否有数字，并统计数字个数！将连续整数输出到一个整数数组中

[解决办法]
[code=c#]
      List <int>list=new List <int>();
      string s = "1sjf36;lj423";
      foreach (char c in s)
        if (c >= 48 && c <= 57)
          list.Add(Convert.ToInt16(c.ToString()));
      int[] a = new int[list.Count];
      for (int i = 0; i < list.Count; i++)
      {
        a[i] = Convert.ToInt32(list[i]);
        Console.WriteLine(a[i]);
      }

C# code

using System.Text.RegularExpressions;string test = "fdas79fs-afs7df76f6dsa799fd";int count = Regex.Matches(test, @"\d").Count;Console.WriteLine("字符串中数字的个数为：{0}", count);Console.WriteLine("连续整数分别为：");MatchCollection mc = Regex.Matches(test, @"\d+");foreach (Match m in mc){    Console.WriteLine(m.Value);}Console.Read();
