在NameValueCollection中編碼值C＃.net

Question

我有一個名稱值集合，它傳遞給一個方法，通過Web客戶端發送到另一個系統。

public string DoExtendedTransferAsString(string operation, NameValueCollection query, FormatCollection formats) 
{ 
    System.Net.WebClient client = new System.Net.WebClient(); 
    client.QueryString = query; 
    client.QueryString["op"] = operation; 
    client.QueryString["session"] = SessionId; 
    using (Stream stream = client.OpenRead(url)) 
    { 
     FormatCollection formats = new FormatCollection(stream); 
    } 
    return formats; 
} 

我需要在裏面的NameValueCollection所有值運行HttpUtility.HtmlEncode但我不確定如何。 NB我不能改變調用代碼，所以它必須是一個NameValueCollection。

感謝

Answer 1

試試這個

myCollection.AllKeys 
    .ToList() 
    .ForEach(k => myCollection[k] = 
      HttpUtility.HtmlEncode(myCollection[k]));

從MSDN：

class MyNewClass 
    { 
     public static void Main() 
     { 
     String myString; 
     Console.WriteLine("Enter a string having '&' or '\"' in it: "); 
     myString=Console.ReadLine(); 
     String myEncodedString; 
     // Encode the string. 
     myEncodedString = HttpUtility.HtmlEncode(myString); 
     Console.WriteLine("HTML Encoded string is "+myEncodedString); 
     StringWriter myWriter = new StringWriter(); 
     // Decode the encoded string. 
     HttpUtility.HtmlDecode(myEncodedString, myWriter); 
     Console.Write("Decoded string of the above encoded string is "+ 
         myWriter.ToString()); 
     } 
    } 

您一個用於/ foreach循環集合中的每個值做編碼部分。

如果這不是你正在尋找的請在問題中更明確。

我認爲這將完成你想要的......

public string DoExtendedTransferAsString(string operation, NameValueCollection query, FormatCollection formats) 
    { 
     foreach (string key in query.Keys) 
     { 
      query[key] = HttpUtility.HtmlEncode(query[key]); 
     } 

     System.Net.WebClient client = new System.Net.WebClient(); 
     client.QueryString = query; 
     client.QueryString["op"] = operation; 
     client.QueryString["session"] = SessionId; 
     using (Stream stream = client.OpenRead(url)) 
     { 
      FormatCollection formats = new FormatCollection(stream); 
     } 
     return formats; 
    } 

注意我在裏面添加的foreach，你只是通過所有的按鍵迭代，使用鍵抓住每一個項目和呼籲的HTMLEncode它把它馬上回來。
