如何将STRING转换为GUID

Question

我需要投一个String到一个Guid.

我正在使用此代码但是

string myUserIdContent = ((Label)row.FindControl("uxUserIdDisplayer")).Text;
Guid myGuidUserId = new Guid(myUserIdContent); // PROBLEM HERE
MembershipUser mySelectedUser = Membership.GetUser(myGuidUserId);

我收到此错误

异常详细信息:System.FormatException:无法识别的Guid格式.

实现结果的正确方法是什么？

Answer 1

使用Guid.TryParse.

      string myUserIdContent = ((Label)row.FindControl("uxUserIdDisplayer")).Text;
      Guid myGuidUserId;
      if (Guid.TryParse(myUserIdContent, out myGuidUserId)
      {
          MembershipUser mySelectedUser = Membership.GetUser(myGuidUserId);
      }
      else
      {
          // throw exception and/or inform user
      }
