对NameValueCollection C#.net中的值进行编码

c# .net

对NameValueCollection C#.net中的值进行编码,c#,.net,namevaluecollection,C#,.net,Namevaluecollection,我有一个名值集合，它被传递到一个方法中，通过web客户端发送到另一个系统 public string DoExtendedTransferAsString(string operation, NameValueCollection query, FormatCollection formats) { System.Net.WebClient client = new System.Net.WebClient(); client.QueryString = query; c

我有一个名值集合，它被传递到一个方法中，通过web客户端发送到另一个系统

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NameValueCollection中的所有值上运行HttpUtility.HtmlEncode，但我不确定如何运行。注意：我无法更改调用代码，因此它必须是NameValueCollection

感谢来自MSDN的

：

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());
      }
   }

在for/foreach循环中为集合中的每个值执行编码部分

如果这不是您想要的，请在问题中更加明确。

我认为这将实现您想要的

    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;
    }

请注意我在这里添加的foreach，您只需迭代所有键，使用键抓取每个项，并在其上调用HtmlEncode并将其放回原位。

试试这个

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

试试这个

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

@Liviu我很抱歉，我认为我是具体的，我想对NameValueCollection中的值执行此操作。我尝试了（int I=0；I
