Question

我正在使用gridview更新客户详细信息。在这里，我使用3层架构。我正在尝试更新某些字段。但是，我最终得到了上面提到的错误。这是我的代码。

protected void MyProfileGridView_RowUpdating(object sender, GridViewUpdateEventArgs e)
    {
        int customerId = Convert.ToInt32(Session["CustomerID"]);

        TextBox name = (TextBox)MyProfileGridView.Rows[e.RowIndex].FindControl("txt_Name");
        TextBox shopName = (TextBox)MyProfileGridView.Rows[e.RowIndex].FindControl("txt_ShopName");
        TextBox address = (TextBox)MyProfileGridView.Rows[e.RowIndex].FindControl("txt_Address");
        TextBox mobile1 = (TextBox)MyProfileGridView.Rows[e.RowIndex].FindControl("txt_Mobile1");
        TextBox mobile2 = (TextBox)MyProfileGridView.Rows[e.RowIndex].FindControl("txt_Mobile2");
        TextBox password = (TextBox)MyProfileGridView.Rows[e.RowIndex].FindControl("txt_Password");

        Customer customer = new Customer();
        customer.CustomerID = customerId;
        customer.CustomerName = name.Text;
        customer.ShopName = shopName.Text;
        customer.Address = address.Text;
        customer.Mobile1 = mobile1.Text;
        customer.Mobile2 = mobile2.Text;
        customer.Password = password.Text;

        CustomerBL.UpdateCustomer(customer);
        MyProfileGridView.EditIndex = -1;
        MyProfileGridView.DataSource = CategoryBL.GetCategories();
        MyProfileGridView.DataBind();
    }

用于更新客户的业务逻辑层代码。

public static void UpdateCustomer(Customer customer)
    {
        string query = "UPDATE [Customers] SET [LoginID] = @LoginID, [Password] = @Password, [CustomerName] = @CustomerName, [ShopName] = @ShopName, [Address] = @Address, [Mobile1] = @Mobile1, [Mobile2] = @Mobile2, [ReferenceNumber] = @ReferenceNumber, [SignUpDate] = @SignUpDate, [Enabled] = @Enabled WHERE [CustomerID] = @CustomerID";
        SqlCommand cmd = new SqlCommand(query);

        cmd.Parameters.AddWithValue("@LoginID", SqlDbType.Text).Value = customer.LoginID;
        cmd.Parameters.AddWithValue("@Password", SqlDbType.Text).Value = customer.Password;
        cmd.Parameters.AddWithValue("@CustomerName", SqlDbType.Text).Value = customer.CustomerName;
        cmd.Parameters.AddWithValue("@ShopName", SqlDbType.Text).Value = customer.ShopName;
        cmd.Parameters.AddWithValue("@Address", SqlDbType.Text).Value = customer.Address;
        cmd.Parameters.AddWithValue("@Mobile1", SqlDbType.Text).Value = customer.Mobile1;
        cmd.Parameters.AddWithValue("@Mobile2", SqlDbType.Text).Value = customer.Mobile2;
        cmd.Parameters.AddWithValue("@ReferenceNumber", SqlDbType.Text).Value = customer.ReferenceNumber;
        cmd.Parameters.AddWithValue("@SignUpDate", SqlDbType.DateTime2).Value = customer.SignUpDate;
        cmd.Parameters.AddWithValue("@Enabled", SqlDbType.Bit).Value = customer.Enabled;
        cmd.Parameters.AddWithValue("@CustomerID", SqlDbType.Text).Value = customer.CustomerID;

        DbUtility.UpdateDb(cmd);
    }

请帮助我。提前致谢。

Answer 1

您的SignUpDate未填充，因此正在使用DateTime.MinValue，这对SqlDbType.DateTime无效但是..对我来说有点令人困惑的部分是你在添加参数时指定SqlDbType.DateTime2 我怀疑你创建表时，实际上是使用SqlDbType.DateTime

无论如何，您需要填写日期，例如

    Customer customer = new Customer();
    customer.SignUpDate = DateTime.Now; //notice this line
    customer.CustomerID = customerId;
    customer.CustomerName = name.Text;
    //etc...

附加信息：SqlDateTime溢出。必须在1/1/1753 12:00:00 AM和12/31/9999 11:59:59 PM之间
