如何在c#中删除带有不同表单查询的列表项？

using System;
using System.Data.SqlClient;

public class Program
{
    public static void Main()
    {
        // 建立与数据库的连接
        string connectionString = "Data Source=(local);Initial Catalog=YourDatabase;Integrated Security=True";
        using (SqlConnection connection = new SqlConnection(connectionString))
        {
            connection.Open();

            // 构建SQL语句
            string sql = "DELETE FROM YourTable WHERE Column1 = @Value1 AND Column2 = @Value2";

            // 创建SqlCommand对象
            using (SqlCommand command = new SqlCommand(sql, connection))
            {
                // 设置参数值
                command.Parameters.AddWithValue("@Value1", "QueryValue1");
                command.Parameters.AddWithValue("@Value2", "QueryValue2");

                // 执行SQL语句
                int rowsAffected = command.ExecuteNonQuery();

                // 输出受影响的行数
                Console.WriteLine("已删除 {0} 行", rowsAffected);
            }
        }
    }
}
