1添加命名空间：using System.Text.RegularExpressions;
2在需要的地方添加如下代码：
string str = "sR seeD ";
MatchCollection mc = Regex.Matches(str.Trim(),"srseed",RegexOptions.IgnoreCase);
if (mc == null)
Response.Write("<script>alert('匹配失败！')</script>");
else
Response.Write("<script>alert('匹配成功！')</script>");
MatchCollection mc = Regex.Matches(str.Trim(),"srseed",RegexOptions.IgnoreCase);
if (mc == null)
Response.Write("<script>alert('匹配失败！')</script>");
else
Response.Write("<script>alert('匹配成功！')</script>");
3这样更可以在cs页面验证aspx的控件，正则表达式！
