如何在C#中自动完成数据库中的同名问题

using System;
using System.Data.SqlClient;

class Program
{
    static void Main()
    {
        string connectionString = "Data Source=YourServer;Initial Catalog=YourDatabase;User ID=YourUsername;Password=YourPassword";
        string query = "SELECT DISTINCT column_name FROM table_name";

        using (SqlConnection connection = new SqlConnection(connectionString))
        {
            connection.Open();

            SqlCommand command = new SqlCommand(query, connection);
            SqlDataReader reader = command.ExecuteReader();

            while (reader.Read())
            {
                string columnName = reader.GetString(0);
                // 处理同名问题的逻辑
                // ...
            }

            reader.Close();
        }
    }
}
