有没有一种简单的方法来在Windows Phone的从URI获取查询字符串参数？ [英] Is there a simple way to get query string parameters from a URI in Windows Phone?

问题描述

我目前使用自定义的URI方案共同验证使用OAuth用户。为了做到这一点，我需要从查询字符串获取某些参数的值。

I'm currently working with a Custom URI Scheme to validate users using OAuth. In order to do this, I need to get the values of certain parameters from the query string.

有一个简单的方法来获得这些信息？或者是我唯一的选择使用正则表达式或其他字符串操作？

Is there a simple way to get this information? Or is my only option to using REGEX or other string manipulation?

我以前发现的东西像ParseQueryString引用，但这些都包含在Windows Phone上没有可用的库。

I have previously found references to things like ParseQueryString, but these are contained in libraries not available on Windows Phone.

推荐答案

很多搜索我的后降落在一个简单的方法。所以只要查询字符串保持相当简单（因为它们是在OAuth的）这种方法应该工作

After a lot of searching I landed on a simple approach. So long as query strings are kept fairly simple (as they are in OAuth) this method should work.

public static Dictionary<string, string> ParseQueryString( string uri ) {

    string substring = uri.Substring( ( ( uri.LastIndexOf('?') == -1 ) ? 0 : uri.LastIndexOf('?') + 1 ) );

    string[] pairs = substring.Split( '&' );

    Dictionary<string,string> output = new Dictionary<string,string>();

    foreach( string piece in pairs ){
        string[] pair = piece.Split( '=' );
        output.Add( pair[0], pair[1] );
    }

    return output;

}
