C#試卷答案（B卷）

一、．

1．inta=int.Parse(Console.ReadLine());2．foreach(intiinArray)

{

Console.WriteLine(i);

}

3．

4．doubleb=Myclass.fphi;

Console.WriteLine(b);Myclassm=newMyclass();

Console.WriteLine(m.nIndex);

5．a(chǎn)=8,b=68a=68,b=8

二．

1.usingSystem;classTest

{staticvoidMain()

{ Console.Write(“請(qǐng)輸入x的值:")；

doublex=double.Parse(Console.ReadLine());int y;

if(x>0)

y=5；elseif(x==0)

y=4；

else

y=3;

Console.WrteLine(“Y={0}“,y)；

}

}

2、classRectangle

{

publicdoublewidth=3;publicdoubleheight=5;publicdoubles=0;

publicRectangle() //構(gòu)造函數(shù)

{

s=width*height;

}

~Rectangle() //析構(gòu)函數(shù)

{

Console.WriteLine("析構(gòu)函數(shù)被自動(dòng)調(diào)用");

}

staticvoidMain(string[]args)

{

Rectangler1=newRectangle(); //創(chuàng)建對(duì)象時(shí)調(diào)用構(gòu)造函數(shù)Console.WriteLine(r1.s);

//自動(dòng)調(diào)用析構(gòu)函數(shù)

}

}

3．usingSystem;

usingSystem.Collections.Generic;usingSystem.Text;

namespaceConsoleApplication2

{

classProgram

{

staticvoidMain(string[]args)

{

workerw=newworker(10000,25,3000,200,150,100,80);w.getpay();

w.print();

}

}

classworker

{

publicintnum;publicintage;publicintpay;publicintwage;publicintsubsidy;publicintrent;publicintwaterfee;publicintelecfee;

publicworker(intnum,intage,intwage,intsubsidy,intrent,intwaterfee,intelecfee)

{

this.num=num;this.age=age;this.wage=wage;this.subsidy=subsidy;this.rent=rent;

this.waterfee=waterfee;this.elecfee=elecfee;

}

publicvoidgetpay()

{

pay=wage+subsidy-rent-waterfee-elecfee;

}

publicvoidprint()

{

Console.WriteLine("no:"+num+" age:"+age+"pay:"+pay);

}

}

}
