Question

C#如何利用while循环输出对象数组的全部信息？具体信息如下。

XueSheng[] a = new XueSheng[5];
a[0] = new XueSheng(5, "张三", 15, "沈阳", "1米8", 100);
Console.WriteLine(a[0].xianshi());

a[1] = new XueSheng();
a[1].Id = 5;
a[1].Name = "张三";
a[1].Nl = 15;
a[1].Dz = "沈阳";
a[1].Sg = "1米8";
a[1].Cj = 100;
Console.WriteLine(a[1].xianshi());

a[2] = new XueSheng(1, "孙强", 16, "大连", "1米7", 99);
Console.WriteLine(a[2].xianshi());
a[3] = new XueSheng(2, "小红", 18, "深圳", "1米8", 96);
Console.WriteLine(a[3].xianshi());

Answer 1

int count =0;
while(count<XueSheng.Length)
{
    if(a[count]!=null)
    {
        Console.Write(a[count].Id.ToString());
        Console.Write(a[count].Name);
        Console.Write(a[count].Nl);
        Console.Write(a[count].Dz);
        Console.Write(a[count].Sg.ToString());
        Console.Write(a[count].Cj);
        Console.WriteLine();
    }
    count++;
}

Answer 2

foreach(XueSheng x in a) Console.WriteLine(x.xianshi());

Answer 3

int i=0;
while(i<a.length){
var cur=a[i];
//输出cur信息.
i++;
}
