手机，重定向将参数％20添加到参数

Question

我有一个移动应用程序，有几个文件夹。这些文件夹作为变量，我将增加参数：从URL

 //Get the URL 
     string url = HttpContext.Current.Request.Url.AbsolutePath; 

     //Location 
     string location = ""; 

     //Check if string contains/
     if (url.Contains('/')) 
     { 
      //Get location 
      string[] words = url.Split('/'); 

      //Set location 
      location = words[1]; 

      //Now check if string contains ? 
      if (location.Contains('?')) 
      { 
       //Remove ? 
       string[] removeQ = location.Split('?'); 

       //Reset location 
       location = removeQ[0]; 
      } 

     } 

我以后的道路我根据手机类型重定向：

 if (Request.UserAgent.ToUpper().Contains("BLACKBERRY")) 
     { 
      //Now we check the version 
      if (double.Parse(Request.Browser.Version) <= 5) 
      { 
       Response.Redirect("http://myWebsite.com/Default.aspx?location= " + location); 
      } 
      else if (double.Parse(Request.Browser.Version) >= 6) 
      { 
       Response.Redirect("http://myWebsite.com/Default.aspx?location= " + location); 
      } 
      else 
      { 
       Response.Redirect("http://myWebsite.com/Default.aspx?location= " + location); 
      } 

     } 
     else if (Request.UserAgent.ToUpper().Contains("HTC")) //HTC phones cannot handle JQuery mobile 
     { 
      Response.Redirect("http://myWebsite.com/Default.aspx?location= " + location); 
     } 
     else if (Request.UserAgent.ToUpper().Contains("ANDROID")) //Certain androids are out of date 
     { 
      if (double.Parse(Request.Browser.Version) > 2) 
      { 
       Response.Redirect("http://myWebsite.com/Default.aspx?location= " + location); 
      } 
      else 
      { 
       Response.Redirect("http://myWebsite.com/Default.aspx?location= " + location); 
      } 

     } 
     else 
     { 
      Response.Redirect("http://myWebsite.com/Default.aspx?location= " + location); 
     } 
    } 

的问题是，它location将在前面添加“％20”。这不会发生，如果我在台式机上测试它，只能在手机上测试。

这是怎么发生的？我怎样才能防止这一点？

Answer 1

删除字符串文字末尾的所有空格，例如改变：

"http://myWebsite.com/Default.aspx?location= " + location 

到

"http://myWebsite.com/Default.aspx?location=" + location 

Answer 2

在URL，空格被编码以％20。您只需删除字符串中的任何尾随或前导空格即可修改该字符串。
