.NET中数字正则

Question

我输入一段字符串,比如:你好999999uuuuu;我就想判断里面的数字,如果有数字就提示错误,

Answer 1

string str="9999aaa";
if(Regex.Match(str,"\d+").Success)
{
//有数字
}

Answer 2

using System;class Test
{
    static void Main()
    {
        bool b = System.Text.RegularExpressions.Regex.Match("999999uuuuu","\\d").Success;
        if (b)
        {
            Console.WriteLine("have numbers");
        }
        else
        {
            Console.WriteLine("no");
        }
        Console.Read();
    }}

Answer 3

 if (Regex.Match(name,"d+").Success)
            {
                Response.Write("<script>alert('不能为数字！');history.go(-1);</script>");
                Response.End();
            }还是错的嘛 

Answer 4

if (Regex.Match(name,"\d+").Success) 

Answer 5

if (Regex.Match(name,@"\d+").Success) //忘转义了，楼主好新手

Answer 6

杂个还是错的呢   if (Regex.Match(name,@"\d+").Success)
            {
                Response.Write("<script>alert('不能为数字！');history.go(-1);</script>");
                Response.End();
            }
还是没有验证的嘛
