c# string 转 GUID

提供两种方法

1.try...catch...

         /*
          * string TO guid
          */
         private static bool ToGuid(string str)
         {
             Guid gv = new Guid();
             try
             {
                 gv = new Guid(str);
             }
             catch (Exception)
             {

             }
             if (gv != Guid.Empty)
             {
                 return true;
             }
             else
             {
                 return false;
             }
         }

2.match匹配

         /*
          * string TO guid
          */
         private static bool ToGuid(string str)
         {
             Match m = Regex.Match(str,@"^[0-9a-f]{8}(-[0-9a-f]{4}){3}-[0-9a-f]{12}$",RegexOptions.IgnoreCase);
             Guid gv = new Guid();
             if (m.Success)
             {
                 gv = new Guid(str);
             }
             if (gv != Guid.Empty)
             {
                 return true;
             }
             else
             {
                 return false;
             }
         }
