基于C#的Escape和Unescape实现 //在C#后台实现JavaScript的函数escape()的字符串转换//些方法支持汉字private string escape(string s){StringBuilder sb = new StringBuilder();byte[] byteArr = System.Text.Encoding.Unicode.GetBytes(s); for (int i = 0; i < byteArr.Length; i += 2){ sb.Append("%u");sb.Append(byteArr[i + 1].ToString("X2"));//把字节转换为十六进制的字符串表现形式 sb.Append(byteArr[i].ToString("X2"));}return sb.ToString(); }//把JavaScript的escape()转换过去的字符串解释回来//些方法支持汉字private string unescape(string s){ string str = s.Remove(0, 2);//删除最前面两个＂%u＂string[] strArr = str.Split(new string[]{"%u"}, StringSplitOptions.None);//以子字符串＂%u＂分隔byte[] byteArr = new byte[strArr.Length * 2];for (int i = 0,j=0; i < strArr.Length;i++,j+=2){byteArr[j + 1] = Convert.ToByte(strArr[i].Substring(0,2), 16); //把十六进制形式的字串符串转换为二进制字节byteArr[j ] = Convert.ToByte(strArr[i].Substring(2, 2), 16);}str = System.Text.Encoding.Unicode.GetString(byteArr); //把字节转为unicode编码return str; } 下面的为不支持汉字的转换： public static string Escape(string str){if (str == null)returnString.Empty; StringBuilder sb = newStringBuilder();int len = str.Length; for […]
