如何將字符串轉換爲字符串包含十六進制字符

我從谷歌代碼說，例如。下面的示例在字符串中包含非ASCII字符。我想要的是寫一個函數，可以將它們全部轉換爲ASCII字符串。如何將字符串轉換爲字符串包含十六進制字符

下面是函數我有，但它並不與上面的字符串摸出：

 public static string DecodeHex(string data) 
    { 
     data = data.Replace("\x22", @""""); 
     data = data.Replace("\x23", "#"); 
     data = data.Replace("\x24", "$"); 
     data = data.Replace("\x25", "%"); 
     data = data.Replace("\x26", "&"); 
     data = data.Replace("\x27", "'"); 
     data = data.Replace("\x28", "("); 
     data = data.Replace("\x29", ")"); 
     data = data.Replace("\x2a", "*"); 
     data = data.Replace("\x2b", "+"); 
     data = data.Replace("\x2c", ","); 
     data = data.Replace("\x2d", "-"); 
     data = data.Replace("\x2e", "."); 
     data = data.Replace("\x2f", "/"); 
     data = data.Replace("\x30", "0"); 
     data = data.Replace("\x31", "1"); 
     data = data.Replace("\x32", "2"); 
     data = data.Replace("\x33", "3"); 
     data = data.Replace("\x34", "4"); 
     data = data.Replace("\x35", "5"); 
     data = data.Replace("\x36", "6"); 
     data = data.Replace("\x37", "7"); 
     data = data.Replace("\x38", "8"); 
     data = data.Replace("\x39", "9"); 
     data = data.Replace("\x3a", ":"); 
     data = data.Replace("\x3b", ";"); 
     data = data.Replace("\x3c", "<"); 
     data = data.Replace("\x3d", "="); 
     data = data.Replace("\x3e", ">"); 
     data = data.Replace("\x3f", "?"); 
     return data; 
    }

感謝答覆。

Uri uri = new Uri(url); 
Console.WriteLine(uri.ToString());

你也可以用下面的方法

HttpUtility.UrlDecode(String) from System.Web

該功能具有更少的開銷比URI（）。對於其他但類似的解碼方案：http://blogs.msdn.com/b/yangxind/archive/2006/11/09/don-t-use-net-system-uri-unescapedatastring-in-url-decoding。 ASPX – K3N

var json1 = DecodeHex(json); 
    var jsonDes = JsonConvert.DeserializeObject<List<Dictionary<string, object>>>(json1); 
    public static string DecodeHex(string data) 
    { 
     data = data.Replace("\\x22", @""""); 
     data = data.Replace("\\x23", "#"); 
    ....... 
    }
