我有一个简单的页面如下： Default.aspx的 %@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %htmlbodyform method="POST" action="Default.aspx"Enter Number: input type="text" name="cNum" va
Default.aspx的
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> <html> <body> <form method="POST" action="Default.aspx"> Enter Number: <input type="text" name="cNum" value="7707744436276244" /><br /> <input type="submit" value="Submit" /> </form> </body> </html>
和Default.aspx.cs背后的代码
using System;
using System.Collections.Generic;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class _Default : System.Web.UI.Page
{
public string ServerSideVariable;
protected void Page_Load(object sender, EventArgs e)
{
string n = String.Format("{0}", Request.Form['cNum']); ERROR Here<--- too many character in character literall....
string pval = "Passed value";
ServerSideVariable = pval;
}
}
为什么会发生错误？
另外我打算在代码后面实现与DB建立连接并将响应返回给ASP.net,任何人都知道这是怎么做到的？
在C#中,’是为字符文字保留的.“是为字符串文字保留的.
char char1 = 'Z'; // Character literal string string1 = "ZZZ"; // String literal
C#参考文献：
> Character literals
> String literals
> [] Operator
请尝试以下方法：
using System;
using System.Collections.Generic;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class _Default : System.Web.UI.Page
{
public string ServerSideVariable;
protected void Page_Load(object sender, EventArgs e)
{
string n = String.Format("{0}", Request.Form["cNum"]); //ERROR Here<--- too many character in character literall....
string pval = "Passed value";
ServerSideVariable = pval;
}
}
