request取值时"未将对象引用设置到对象的实例"是什么错误啊?
<body>
<form id= "form1 " runat= "server " action= "get.aspx ">
<div>
<asp:TextBox ID= "iname " runat= "server "> </asp:TextBox> <br />
<asp:TextBox ID= "password " runat= "server "> we </asp:TextBox> <br />
<asp:Button ID= "Button1 " runat= "server " Text= "Button " OnClick= "Button1_Click " /> </div>
</form>
</body>
</html>
c#文件为
Response.Redirect( "get.aspx ");
get.aspx为
public partial class get : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
//string thename = Request.QueryString[ "iname "].ToString();
//string thepasswore = Request.QueryString[ "password "].ToString();
string thename, thepassword;
thename = Request.Form[ "iname "].tostring();
thepassword = Request.Form[ "password "].tostring();
Response.Write(thename+ " <br> ");
Response.Write(thepassword);
}
}
用的 vs2005的。 编译结果 "未将对象引用设置到对象的实例 "是什么错误啊?
[解决办法]
thename = Request.Form[ "iname "].tostring();
你的 "iname " 在哪传的?
[解决办法]
thename = Request.Form[ "iname "].tostring();
thepassword = Request.Form[ "password "].tostring()
这两个其中有错误~如果你iname或者怕ssword的值为null~用tostring就会提示这样的错误
[解决办法]
加上判断就不错了
if (Request.Form[ "iname "] != null)
{
thename = Request.Form[ "iname "].ToString();
}
else
{
thename = "hello ";
}
if (Request.Form[ "password "] != null)
{
thepassword = Request.Form[ "password "].ToString();
}
else
{
thepassword = "world ";
}
页面第一次加载输出为：
hello
world
点击按钮之后：就是在文本框中输入的值
[解决办法]
等等，貌似看错了你的问题，你的意思是 <asp:TextBox ID= "iname " runat= "server "> </asp:TextBox> 在一个页面，然后将这些值传到get.aspx页面？
如果这样的话，Response.Redirect( "get.aspx ");又没有传值过去，到底是什么意思？
