無法保存數據庫中的文件上傳文件名

Question

我找不出正確的代碼來保存數據庫中的文件名字符串。我的代碼如下：

 FileUpload1.SaveAs(Server.MapPath("pimages/" + FileUpload1.FileName)) 
       MsgBox(FileUpload1.FileName) 
      Dim newUsr As MembershipUser = Membership.GetUser() 
      Dim newUserId As Guid = CType(newUsr.ProviderUserKey, Guid) 

      ' Insert a new record into UserProfiles 
      Dim connectionString As String = ConfigurationManager.ConnectionStrings("LocalSqlServer").ConnectionString 
      Dim insertSql As String = "UPDATE UserProfiles Set (Pic = @Pic) Where (UserId = @UserID)" 

      Using myConnection As New SqlConnection(connectionString) 
       myConnection.Open() 
       Dim myCommand As New SqlCommand(insertSql, myConnection) 

       myCommand.Parameters.AddWithValue("@UserId", newUserId) 
       myCommand.Parameters.AddWithValue("@Pic", FileUpload1.FileName) 

       myCommand.ExecuteNonQuery() 
       myConnection.Close() 
      End Using 

有人可以糾正這個請嗎？

我相信你的問題可能與你的用戶ID有關。當使用動態SQL時，GUID和字符串都需要用單引號括起來：

Dim insertSql As String = "UPDATE UserProfiles Set (Pic = '@Pic') Where (UserId = '@UserID')"
