c# - 如何将 STRING 转换为 GUID

Question

我需要将 String 转换为 Guid。

我正在使用这段代码，但是

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

我收到这个错误

Exception Details: System.FormatException: Unrecognized Guid format.

达到结果的正确方法是什么？

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
      }
