SQL query可以在EA中使用，但不能在应用程序接口上使用C#

using System;
using System.Data.SqlClient;

class Program
{
    static void Main()
    {
        string connectionString = "your_connection_string_here";
        string query = "SELECT * FROM YourTable WHERE Id = @Id";

        using (SqlConnection connection = new SqlConnection(connectionString))
        {
            SqlCommand command = new SqlCommand(query, connection);
            command.Parameters.AddWithValue("@Id", 1);

            try
            {
                connection.Open();
                SqlDataReader reader = command.ExecuteReader();
                while (reader.Read())
                {
                    Console.WriteLine(reader["ColumnName"].ToString());
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine("Error: " + ex.Message);
            }
        }
    }
}

using System;
using System.Linq;
using YourDbContextNamespace;

class Program
{
    static void Main()
    {
        using (YourDbContext context = new YourDbContext())
        {
            var result = context.YourTable.Where(x => x.Id == 1).ToList();
            foreach (var item in result)
            {
                Console.WriteLine(item.ColumnName);
            }
        }
    }
}
