31. 当文件在不同目录下,需要获取数据库连接字符串(如果连接字符串放在Web.config,然后在Global.asax中初始化)
在Application_Start中添加以下代码:
字符型转换 转为字符串
截取字串的一部分,参数1为左起始位数,参数2为截取几位。 如:string s1 = str.Substring(0,2);
34.在自己的网站上登陆其他网站:(如果你的页面是通过嵌套方式的话,因为一个页面只能有一个FORM,这时可以导向另外一个页面再提交登陆信息)
下面是获取用户输入的登陆信息的代码:
在Application_Start中添加以下代码:
Application[
"
ConnStr
"
]
=
this
.Context.Request.PhysicalApplicationPath
+
ConfigurationSettings.
AppSettings[ " ConnStr " ].ToString();
32.变量.ToString()
AppSettings[ " ConnStr " ].ToString();
字符型转换 转为字符串
12345
.ToString(
"
n
"
);
//
生成12,345.00
12345 .ToString( " C " ); // 生成¥12,345.00
12345 .ToString( " e " ); // 生成1.234500e+004
12345 .ToString( " f4 " ); // 生成12345.0000
12345 .ToString( " x " ); // 生成3039(16进制)
12345 .ToString( " p " ); // 生成1,234,500.00%
33.变量.Substring(参数1,参数2);
12345 .ToString( " C " ); // 生成¥12,345.00
12345 .ToString( " e " ); // 生成1.234500e+004
12345 .ToString( " f4 " ); // 生成12345.0000
12345 .ToString( " x " ); // 生成3039(16进制)
12345 .ToString( " p " ); // 生成1,234,500.00%
截取字串的一部分,参数1为左起始位数,参数2为截取几位。 如:string s1 = str.Substring(0,2);
34.在自己的网站上登陆其他网站:(如果你的页面是通过嵌套方式的话,因为一个页面只能有一个FORM,这时可以导向另外一个页面再提交登陆信息)
<SCRIPTlanguage="javascript">

文本框的名称必须是你要登陆的网页上的名称,如果源码不行可以用vsniffer 看看。

下面是获取用户输入的登陆信息的代码:

try

inta=name.IndexOf("@",0,name.Length);
f_user.Value=name.Substring(0,a);
f_domain.Value=name.Substring(a+1,name.Length-(a+1));
f_pass.Value=Request.QueryString["Psw"];
}
catch
{
Script.Alert("错误的邮箱!");
Server.Transfer("index.aspx");
}
35.警告窗口
