我有以下HTML源代码
<form name="Register1" action="Register.aspx" id="registerform" method="post"
runat="server" style="margin-top: 15px;">
<input type="radio" name="Gender" value="male" />male
<input type="radio" name="Gender" value="female" />female
</form>
我的问题是如何在c#页面中将所选值变为变量？
我试过这个:
Gender = Request.Form["Gender"].ToString();
但它不起作用......
我有以下C#代码:
ArticleContent = ds1.Tables[0].Rows[i]["ArticleContent"].ToString();
if (ArticleContent.Length > 260)
{
ArticleContent = ArticleContent.Remove(ArticleContent.IndexOf('.', 250)) + "...";
}
这里的问题是我收到此错误消息:
StartIndex不能小于零.
为什么以及如何解决它？

哪个应该检查会话是否存在,如果不存在,用户重定向,问题是这个条件总是如此,即使会话确实存在,我的问题是如何解决它？
我有以下PHP代码:

www.google.com;www.yahoo.com;www.gmail.com
我的问题是我如何分离这些链接,以便我可以添加标签的所有链接<a>以及链接末尾的标记</a>？
我应该得到这个:
<a>www.google.com</a>;<a>www.yahoo.com</a>;<a>www.gmail.com</a>
如果解决方案尽可能简单并使用该IndexOf方法,我将感激不尽.
我知道这可能是一个非常简单的问题,我试图在网上找到解决方案,但我无法理解......我有以下C#/ ASPX代码:
SelectArea += "<select name=\"Area\" id=\"area\">" + "<option value=\"Default\" style=\"display:none;\">SELECT AREA</option>";
for (i = 0; i < ds.Tables[0].Rows.Count; i++)
{
AreaName = ds.Tables[0].Rows[i]["AreaName"].ToString();
SelectArea += string.Format("<option value=\"{0}\"/>{0}</option>", AreaName);
}
SelectArea += "</select>";
这个javascript函数在提交后发生
function validateProfile() {
var el = document.getElementById("area").value;
alert(el);
}
我想要一些如何获取列表中所选值的编号.我试过上面的代码,但它不起作用.
希望得到帮助,谢谢!
