类的参数使用 [英] Class use of the parameter

问题描述

你好，我想现在学习这一点，当普通代码直接采用连接到sql类端的参数值时，但是我不知道该怎么办.为了提供下面提到的代码的这一部分的示例，您需要使用类来处理这些参数.我如何披露自己的示例，对此感到非常满意.在此先感谢您，祝您度过愉快的一天.

Hello, I want to learn this now, when the normal code directly taking on the value of parameters mentioned connecting to sql class side, but I do not know how you can do. To give an example of this part of the code mentioned below, there are the parameters you need to do with class How do I disclose my examples were very pleased with the stay. Thanks in advance have a nice day.

SqlConnection cnn = new SqlConnection("ConnectionString");

            cnn.Open();
            SqlCommand cmd = new SqlCommand("Insert into Products(UrunID,CategoryID) values(@id,@katid)",cnn);

            cmd.Parameters.AddWithValue("@id", value.Text);
            cmd.Parameters.AddWithValue("@katid",value.Text);

            cmd.ExecuteNonQuery();

            cnn.Close();

推荐答案

我不确定这是否是您想要的

Im not sure if this is what you want

#region

using System;
using System.Collections.Generic;
using System.Data.SqlClient;
using System.Text;

#endregion

namespace ConsoleApplication1
{
    internal class Program
    {
        private static void Main(string[] args)
        {
            loadinfo(args[0], args[1]);
        }

        private static void loadinfo(string x, string y)
        {
            var cnn = new SqlConnection("ConnectionString");

            cnn.Open();
            var cmd = new SqlCommand("Insert into Products(UrunID,CategoryID) values(@id,@katid)", cnn);

            cmd.Parameters.AddWithValue("@id", x);
            cmd.Parameters.AddWithValue("@katid", y);

            cmd.ExecuteNonQuery();

            cnn.Close();
        }
    }
}

您要问的只是 ^ ]，您可以在创建类的实例时传递它..

请参阅相同的文章:

您还应该了解 C#4.0命名用于提高代码质量的参数 [

The thing which you are asking is nothing but Constructor With Parameters[^], which you can pass while creating the instance of the class..

Refer the articles for the same:

Constructor parameter validation in C# - Best practices[^]

You should also know about C# 4.0 Named Parameters for better code quality[^]
