方法，C#中的继承类和字符串 [英] Methods , Inheritance Class in C# and strings

问题描述

 

我是初学者程序员喜欢基本学习C# ，请协助我，此程序有什么问题在C#中.

在这里我创建了一个简单的程序链类或继承:我犯了什么错误?

介绍一下字符串用户值；

书

{

void Main( 字符串 [] args)

{

作者 = ;

标题 = ;

价格 = 50;

页面 = 350;

股票 = 13;

void show()

{

.WriteLine( " " );

.WriteLine( "书籍 信息" );

.WriteLine( " 图书作者:" +作者)；

.WriteLine( "书 标题" :+标题)；

.WriteLine( " 图书价格:" +价格)；

.WriteLine( " 页数:" +页);

.WriteLine( " 图书库存:" 股票)；

.ReadLine();

.Read();

}

HardwareBook :

{

硬件标题 = ;

出版商 = ;

void showdata()

{

系统. .WriteLine( );

系统. .WriteLine( );

系统. .WriteLine( + hardwareTitle);

系统. .WriteLine( +发布者)；

系统. .WriteLine( );

.ReadLine();

.Read();

}

}

SoftwareBook :

{

SoftwareName = ;

softwareVersion = ;

void showdetails()

{

show();

.WriteLine( "软件 图书信息" );

.WriteLine( "软件 名称:" + SoftwareName)；

.WriteLine( "软件 版本:" + softwareVersion);

.WriteLine( " " );

}

静态

{

h =

span style ="font-size:small"> s =

s.showdetails();

h.showdata();

}

}

}

}

}

解决方案

我已经更正了您的代码，使其可以正常工作，您可以将自己的代码与我的代码进行比较，以查看自己的工作错误的.我不确定您到底想做什么(我想是继承)，所以如果您有任何疑问，请告诉我.

使用系统；

命名空间BooksTreasure

字符串作者="steve"；
字符串标题=手册"；
整型价格= 50;
int页数= 350；
内部库存= 13;

公共无效的show()

Console.WriteLine("Books Information")；
Console.WriteLine(书作者:" +作者)；

Console.WriteLine(书库:" +书库)；
}
}

公共无效的showdata()
{

}

类SoftwareBook:硬件手册

字符串软件版本＝玛丽·彼得森"；

公共无效的showdetails()
{

Console.WriteLine(");

}
}

类DisplayData
{
公共静态void Main(String [] args)
{
SoftwareBook s =新的SoftwareBook();
s.showdetails();
s.showdata();

Console.ReadLine();
}
}
} 

 Hi,

I beginner to  programmer like  Basic Learn the C#  , Please kindly assist to me ,  what is issue on this program  in C#.

Here it is  I created the Program a simple  Chain Class or Inheritance : And What were the mistake I did?

Tell about  the strings user value;

解决方案

I have corrected your code so that it is working, you can compare your code to mine to see what you did wrong. I am not sure what exactly you are trying to do (I suppose inheritance) so if you have any questions let me know.

using System;

namespace BooksTreasure
{
	class Book
	{
		String author = "steve";
		String title = "Handbook";
		int price = 50;
		int pages = 350;
		int stock = 13;

		public void show()
		{
			Console.WriteLine(" ");
			Console.WriteLine("Books Information");
			Console.WriteLine("Book Author: " + author);
			Console.WriteLine("Book Title: " + title);
			Console.WriteLine("Book Price:" + price);
			Console.WriteLine("Number of Pages: " + pages);
			Console.WriteLine("Book Stock:" + stock);
		}
	}

	class HardwareBook : Book
	{
		String hardwareTitle = "Printers";
		String publisher = "Tom Wilkins";

		public void showdata()
		{
			Console.WriteLine(" ");
			Console.WriteLine("Hardware Books Informations");
			Console.WriteLine("Hardware Title:" + hardwareTitle);
			Console.WriteLine("Publisher Name" + publisher);
			Console.WriteLine(" ");
		}

	}

	class SoftwareBook : HardwareBook
	{
		String softwareName = "Windows";
		String softwareVersion = "Mary Peterson";

		public void showdetails()
		{
			show();
			Console.WriteLine(" ");
			Console.WriteLine("Software Books Information");
			Console.WriteLine("Software Name: " + softwareName);
			Console.WriteLine("Software Version: " + softwareVersion);
			Console.WriteLine(" ");
		}
	}

	class DisplayData
	{
		public static void Main(String[] args)
		{
			SoftwareBook s = new SoftwareBook();
			s.showdetails();
			s.showdata();

			Console.ReadLine();
		}
	}
}
