我想在頁面加載事件時傳遞@UserID。

MembershipUser CurrentUser = Membership.GetUser(); 

@UserID = (Guid)CurrentUser.ProviderUserKey; 

但我該怎麼做呢？

Answer 1

MembershipUser CurrentUser = Membership.GetUser(); 
Guid userid = (Guid)CurrentUser.ProviderUserKey; 
Answered.SelectParameters.Add("UserID", userid.ToString().Trim());
