判断字符串是否能转化成Guid_li.的博客

string s  =  null;
Guid  gv  =  Guid.Empty;
try
{
gv  =  new  Guid(s);
}
catch
{

}
if (gv  != Guid.Empty)
{
//转换成功
}

===================================

GuidConverter gc = new GuidConverter();
gc.ConvertFrom(str);

============================

没有“-”也是允许的
@ "^[0-9a-f]{8}(-[0-9a-f]{4}){3}-[0-9a-f]{12}$|^[0-9a-f]{32}$ ",

====================================

private bool IsGuid(string strToValidate)
       {
           bool isGuid = false;
           string strRegexPatten = @"^(\{){0,1}[0-9a-fA-F]{8}\-[0-9a-fA-F]{4}\-[0-9a-fA-F]{4}\-[0-9a-fA-F]{4}\-[0-9a-fA-F]{12}(\}){0,1}$";
           if (strToValidate != null && !strToValidate.Equals(""))
           {
               isGuid =System.Text.RegularExpressions.Regex.IsMatch(strToValidate, strRegexPatten);
           }
           return isGuid;
       }
