如何传递一个包含&的字符串在它内部作为wp8中的参数 [英] How Do I Pass A String That Has & Inside It as a parameter in wp8

问题描述

//这是我传递的字符串

  string  myItem =   Love& Drugs; 

 NavigationServices.Navigate（ new  Uri（ string  .Format（< span class =code-string>  / Views / Page.xaml？item = {0}，myItem）））; 

//这是我在OnNavigatedTo方法中检索它的方式

 MyTextBox.Text = NavigationContext.QueryString [  item]; 

//输出是

爱

我的问题是为什么不是从& Drugs开始或检索的字符串的其余部分，或者我做错了什么？

解决方案

D.国内危险化学品。请问HttpUtility.UrlEncode有帮助吗？

你需要对URL进行编码。 [ ^ $



使用System.Net添加; 位于代码文件的顶部。

使用 WebUtility.UrlEncode方法 [ ^ ]编码URL：

  string  encodedItem = WebUtility.UrlEncode（myItem）; 
 NavigationServices.Navigate（ new  Uri（ string  .Format（  / Views / Page.xaml？item = {0}，encodedItem）））; 

//Here is the string i am passing

string myItem = "Love & Drugs";

NavigationServices.Navigate(new Uri(string.Format("/Views/Page.xaml?item={0}",myItem)));

//this is how i retrieve it in OnNavigatedTo method

MyTextBox.Text = NavigationContext.QueryString["item"];

//output is

Love

My question is why isn't the rest of the string starting from "& Drugs" being passed or retrieved or i'm i doing something wrong??

解决方案

Dunno. Will HttpUtility.UrlEncode help?

You need to encode the URL.[^]

Add using System.Net; at the top of your code file.
Use the the WebUtility.UrlEncode method[^] to encode the URL:

string encodedItem = WebUtility.UrlEncode(myItem);
NavigationServices.Navigate(new Uri(string.Format("/Views/Page.xaml?item={0}",encodedItem)));
