Most optimal way to parse querystring within a string in C#
提问by jpkeisala
I have a querystring alike value set in a plain string. I started to split string to get value out but I started to wonder that I can proabably write this in one line instead. Could you please advice if there is more optimal way to do this?
我在普通字符串中设置了一个类似查询字符串的值。我开始拆分字符串以获取值，但我开始怀疑我是否可以将其写在一行中。如果有更好的方法来做到这一点，您能否提出建议？
I am trying to read "123" and "abc" like in Request.QueryString but from normal string.
我试图在 Request.QueryString 中读取“123”和“abc”，但从普通字符串中读取。
protected void Page_Load(object sender, EventArgs e)
{
string qs = "id=123&xx=abc";
string[] urlInfo = qs.Split('&');
string id = urlInfo[urlInfo.Length - 2];
Response.Write(id.ToString());
}

You can do it this way:
你可以这样做：
using System.Collections.Specialized;
NameValueCollection query = HttpUtility.ParseQueryString(queryString);
Response.Write(query["id"]);
Hope it helps.
希望能帮助到你。

Look at HttpUtility.ParseQueryString. Don't reinvent the wheel.
看看HttpUtility.ParseQueryString。不要重新发明轮子。

RichardOD is on it with HttpUtility.ParseQueryStringbut don't forget to look at TryParse.
RichardOD 与HttpUtility.ParseQueryString一起 使用，但不要忘记查看TryParse.
You can TryParse int, DateTimes etc
