在winform项目中如何实现类似将“中国”变为“%D6%D0”的转换

Question

URLEncode()是在web项目中将汉字进行转码的，但是在winform项目中如何实现类似将“中国”变为“%D6%D0”的转换

Answer 1

string s = "中国";
byte[] data = Encoding.GetEncoding(936).GetBytes(s);
//非Linq写法
StringBuilder builder = new StringBuilder();
foreach (byte b in data)
{
    builder.Append("%" + b.ToString("X2"));
}
string result = builder.ToString();
//linq的写法
result = string.Join("%", data.Select(b => b.ToString("X2")).ToArray());

Answer 2

        public static string UrlEncode(string originalString)
        {
            byte[] bytes = Encoding.Default.GetBytes(originalString);
            System.IO.StringWriter stringWriter = new System.IO.StringWriter();
            for (int i = 0; i < bytes.Length; i++)
            {
                byte b = bytes[i];
                if (((b >= 48) && (b <= 57)) 
                || ((b >= 65) && (b <= 90)) 
                || ((b >= 97) && (b <= 122))) 
                {
                    stringWriter.Write((char)b);
                }
                else if (b == 32)
                {
                    stringWriter.Write("+");
                }
                else
                {
                    stringWriter.Write("%{0:x2}", b);
                }            }
            return stringWriter.ToString();
        }
