Question

我有两个表经销商和客户。管理员将添加经销商字段并为客户提供参考编号。客户必须在网站注册时获取该参考编号和类型。在后端，客户编写的参考编号应与他提供的参考编号相匹配。如果它是相同的，那么他可以登录。否则，他将看到错误消息。

在这里，我无法比较参考编号。价值没有过去。

protected void SignInButton_Click(object sender, EventArgs e)
    {
        int customerID;

        Customer customer = new Customer();

        customer.CustomerName = CustomerNameTextBox.Text;
        customer.ShopName = ShopNameTextBox.Text;
        customer.Address = AddressTextBox.Text;
        customer.Mobile1 = Mobile1TextBox.Text;
        customer.Mobile2 = Mobile2TextBox.Text;
        customer.ReferenceNumber = ReferenceNumberTextBox.Text;
        customer.LoginID = Mobile1TextBox.Text;
        customer.Password = RandomNoGenerator.GenerateRandomNo();
        customer.SignUpDate = DateTime.Now;
        customer.Enabled = true;


        try
        {
            Reseller reseller = new Reseller();

            if (customer.ReferenceNumber == reseller.ReferenceNumber)
            {
                //MessageLabel.Text = "Customer successfully added";
                customerID = CustomerBL.AddCustomer(customer);
                MessageLabel.Text = "You've successfully signed up!";
                Response.Redirect("UserSignUpSuccess.aspx?CustomerID=" + customerID);
            }
            else
            {
                MessageLabel.Text = "Please Provide Same Reference Number";
            }
            //customerID = CustomerBL.AddCustomer(customer);
            //MessageLabel.Text = "You've successfully signed up!";
            //Response.Redirect("UserSignUpSuccess.aspx?CustomerID=" + customerID);
        }
        catch (Exception ex)
        {
            MessageLabel.Text = "Some error occured while processing the request. Error Description <br/>" + ex.Message;
        }

业务逻辑层代码

public class CustomerBL
{
    public static int AddCustomer(Customer customer)
    {
        int customerID;
        SqlCommand cmd = new SqlCommand();
        cmd.CommandText = "INSERT INTO [Customers] ([LoginID], [Password], [CustomerName], [ShopName], [Address], [Mobile1], [Mobile2], [ReferenceNumber], [SignUpDate], [Enabled]) " +
        "VALUES (@LoginID, @Password, @CustomerName, @ShopName, @Address, @Mobile1, @Mobile2, @ReferenceNumber, @SignUpDate, @Enabled); SELECT @@IDENTITY";

        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;

        customerID = DbUtility.UpdateDbGetIdentity(cmd);
        return customerID;
    }

您正在创建Reseller个实例，但在使用它之前不进行初始化

Reseller reseller = new Reseller();

            if (customer.ReferenceNumber == reseller.ReferenceNumber)
            {

假设默认构造函数没有为ReferenceNumber实例设置Reseller，您可能希望在使用它之前对其进行初始化。

从两个表中共同引用参考号进行登录时获取错误
