Question

我从谷歌那里得到一个代码来说。下面的示例包含字符串中的非ascii字符。我想要的是编写一个可以将它们全部转换为ASCII字符串的函数。

这是我的功能，但它不能解决上面的字符串：

        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;
    }

感谢您的回复。

string url = "https://www.google.com/complete/search?client\x3dserp\x26hl\x3den\x26sugexp\x3dles%3B\x26gs_nf\x3d3\x26pq\x3dC%23%20decode%20hex%20string%20to%20string\x26cp\x3d11\x26gs_id\x3d3w8\x26xhr\x3dt\x26q\x3dhow%20to%20conv\x26tch\x3d1\x26ech\x3d78\x26psi\x3dDrqDUKC_I86fiAfLrYCgCw.1350810126009.3";
Uri uri = new Uri(url);
Console.WriteLine(uri.ToString());

Answer 2

您也可以使用以下方法

HttpUtility.UrlDecode(String) from System.Web

Answer 3

    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", "#");
    .......
    }
