Have a look at <a href="http://msdn.microsoft.com/en-us/library/system.web.httputility.parsequerystring.aspx" rel="noreferrer">HttpUtility.ParseQueryString()</a> It'll give you a <code>NameValueCollection</code> instead of a dictionary, but should still do what you need.

The other option is to use <code>string.Split()</code>.

<pre><code> string url = @"http://example.com/file?a=1&amp;b=2&amp;c=string%20param";
 string[] parts = url.Split(new char[] {'?','&amp;'});
 ///parts[0] now contains http://example.com/file
 ///parts[1] = "a=1"
 ///parts[2] = "b=2"
 ///parts[3] = "c=string%20param"
</code></pre>

Use this:

<pre><code>string uri = ...;
string queryString = new System.Uri(uri).Query;
var queryDictionary = System.Web.HttpUtility.ParseQueryString(queryString);

This code by Tejs isn't the 'proper' way to get the query string from the URI:

<pre><code>string.Join(string.Empty, uri.Split('?').Skip(1));

I have a uri string like: <a href="http://example.com/file?a=1&amp;b=2&amp;c=string%20param" rel="noreferrer">http://example.com/file?a=1&amp;b=2&amp;c=string%20param</a>

Is there an existing function that would convert query parameter string into a dictionary same way as ASP.NET Context.Request does it.

I'm writing a console app and not a web-service so there is no Context.Request to parse the URL for me.

I know that it's pretty easy to crack the query string myself but I'd rather use a FCL function is if exists.

Get individual query parameters from Uri

我有一个uri字符串，比如：是否有一个现有的函数可以将查询参数字符串转换为字典，方法与ASP.NET Context.Request相同。我正在编写一个控制台应用程序，而不是web服务，所以没有Context.Request为我解析网址。我知道我自己很容易破解查询字符串，但我宁愿使用FCL函数。
