捕获数据从网址

我想保存我的网页地址的变量，但我不断收到的捕获数据从网址

Cannot implicitly convert type 'System.Collections.Specialized.NameValueCollection' to 'string'

一个错误，这是我的语法

protected void Page_Load(object sender, EventArgs e) 
{ 
    GetKeyInfo(); 
} 

protected void GetKeyInfo() 
{ 
    //The below line is the problem line 
    string fulladdress = HttpContext.Current.Request.Url.Query; 
    Response.Write(fulladdress); 
    string parsed = System.Web.HttpUtility.ParseQueryString(fulladdress); 
}

这是我在试图运行这个地址时显示的地址 http://www.internaltesting.com/PassingDataTest/default.aspx?Information=https://XXX.XXX.X.XXX/all?token=1&cid=1832&employeeid=16432

这是给

错误是告诉你问题是什么..你试图将一个列表分配给一个字符串如果你将字符串改为'var parsed'，它会将你的代码编译或更改为'NameValueCollection parsed = System.Web.Http Utility.ParseQueryString（“myAddress”）;'并添加到类的顶部使用以下'使用System.Collections.Specialized;'谷歌工作在你的脖子上..？看看msdn文档-https：//msdn.microsoft.com/en-us/library/ms150046（v = vs.110）.aspx – MethodMan

@MethodMan - var也会抛出一个错误 –

不，它不会。我测试过它和它编译..请粘贴一个示例是什么fulladdress是当你调试代码.. – MethodMan

System.Web.HttpUtility.ParseQueryString回报NameValueCollection含所有查询字符串参数，它不是一个单一的字符串。

var parsed = System.Web.HttpUtility.ParseQueryString(fulladdress); 
string singleParam = parsed.Get("OneParam");

或古.NET/C＃版本不支持var：

System.Collections.Specialized.NameValueCollection parsed = System.Web.HttpUtility.ParseQueryString(fulladdress); 
string singleParam = parsed.Get("OneParam");

参见： https://msdn.microsoft.com/en-us/library/ms150046.aspx（HttpUtility.ParseQueryString法）和How to read the query string params of a ASP.NET raw URL?
