SqlCommand在dbtype int外键上不起作用

using System;
using System.Data.SqlClient;

class Program
{
    static void Main()
    {
        string connectionString = "Data Source=your_server;Initial Catalog=your_database;Integrated Security=True";
        int customerId = 1;

        string sql = "SELECT * FROM Orders WHERE CustomerID = @CustomerID";
        using (SqlConnection connection = new SqlConnection(connectionString))
        {
            SqlCommand command = new SqlCommand(sql, connection);
            command.Parameters.AddWithValue("@CustomerID", customerId);
            connection.Open();
            SqlDataReader reader = command.ExecuteReader();
            while (reader.Read())
            {
                Console.WriteLine($"Order ID: {reader["OrderID"]}, Customer ID: {reader["CustomerID"]}");
            }
            reader.Close();
        }
    }
}
