基础测试题解答记录。
1、编写程序计算1+2+3+....+100的和。
int m=0;
for (int i= 0; i<= 100; i++)
{
m += i;
}
MessageBox.Show(m.ToString ());
2、已知一个int数组, 编程从数组中获取最大数。
int[] str={3,7,9,2,6,8,5,29};
int s = str[0];
for (int i = 0; i < str.Length; i++)
{
if (str[i] > s)
{
s = str[i];
}
}
MessageBox.Show(s.ToString ());
3、用户输入一个“2008-01-02”格式的日期，分析用户输入的日期然后按照“2008年1月2日”的格式重新输出。
方法一：
string s = "2008-01-02";
string[] str = s.Split('-');
string newtimes = string.Format("{0}年{1}月{2}日", str[0], str[1].ToString()[1], str[2].ToString()[1]);
MessageBox.Show(newtimes);
方法二：
string s = "2008-01-02";
DateTime dt = Convert.ToDateTime(s);
MessageBox.Show(dt.ToLongDateString());
4、编写一个类Person，为Person类定义年龄、姓名两个属性，并且定义一个SayHello方法，方法执行时输出“我是***我的年龄是***”；定义一个Chinese类从Person类继承。
public class Person
{
public int old{ set; get;}
public string Uname{ set;get;}
public void SayHello()
{
Console.WriteLine("我是{0}，我的年龄是{1}", Uname, old);
}
}
public class Chinese : Person
{
public string company { get; set; }
public void cia()
{
Console.WriteLine("我的名字叫{0},我{1}岁了,我来自{2}。", Uname, old, company);
}
}
class Program
{
static void Main(string[] args)
{
Chinese chzn=new Chinese ();
Console.WriteLine("名称:");
chzn.Uname = Console.ReadLine();
Console.WriteLine("年龄:");
chzn.old = Convert .ToInt32(Console.ReadLine());
Console.WriteLine("国籍:");
chzn.company = Console.ReadLine();
chzn.cia();
Console.ReadLine();
}
}
5、不借助于Dreamweaver、VisualStudio等开发工具，使用记事本等文本编辑器编写下面的HTML页面：
<html>
<head>
<title>test</title>
<style type="text/css">
table
{
background: #F7F7F7;
border: 1px #C7D1DD solid;
border-collapse: collapse;
font-size: 12px;
width: 500px;
}
table th
{
background: #C5E3FD;
text-align: left;
}
table tr
{
height: 31px;
}
table tr td
{
border: 1px #CECECE solid;
}
.tright
{
text-align: right;
width: 152px;
}
.tcenter
{
text-align: center;
}
.w89
{
width: 89px;
}
.tfloat
{
float: left;
display: block;
margin: 0;
padding: 0;
}
input[type="text"], input[type="password"]
{
height: 22px;
margin: 2px;
}
.lineheight26
{
line-height: 26px;
}
</style>
</head>
<body>
<form id="myform">
<table>
<tr>
<th colspan="2">
必填信息
</th>
</tr>
<tr>
<td class="tright">
登陆名
</td>
<td>
<input type="text" id="uname" class="tfloat" /><p id="altuname" class="tfloat lineheight26">
(只能用英文，数字和下划线)</p>
</td>
</tr>
<tr>
<td class="tright">
密码
</td>
<td>
<input id="Password1" type="password" class="tfloat"/><p id="altpass" class="tfloat lineheight26">
(密码必须大于6位，区分大小写)</p>
</td>
</tr>
<tr>
<td class="tright">
确认密码
</td>
<td>
<input id="Password2" type="password" class="tfloat"/><p id="altpass2" class="tfloat lineheight26">
</p>
</td>
</tr>
<tr>
<td class="tright">
邮件地址
</td>
<td>
<input type="text" id="mail1" class="tfloat"/><p id="altmail" class="tfloat lineheight26">
</p>
</td>
</tr>
<tr>
<td class="tright">
确认邮件地址
</td>
<td>
<input type="text" id="mail2" class="tfloat" /><p id="altmail2" class="tfloat lineheight26">
</p>
</td>
</tr>
<tr>
<td colspan="2" class="tcenter">
<input id="Submits" type="button" value="提交" class="w89" />
<input id="Resets" type="reset" value="重填" class="w89" />
</td>
</tr>
</table>
</form>
</body>
</html>
6、使用JavaScript验证第5题的HTML表单。要求如下：“登录名”必须是字母数字或下划线, 不能以数字开头；密码为6-16位字母、数字或者下划线.；密码和确认密码一致；邮件地址是正确的邮件地址格式；邮件地址和确认邮件地址一致。
