I need some help with JS code translation to C#. JS Code:
function Decription(string) {
var newString = '',
char, codeStr, firstCharCode, lastCharCode;
var ft = escape(string);
string = decodeURIComponent(ft);
for (var i = 0; i < string.length; i++) {
char = string.charCodeAt(i);
if (char > 132) {
codeStr = char.toString(10);
firstCharCode = parseInt(codeStr.substring(0, codeStr.length - 2), 10);
lastCharCode = parseInt(codeStr.substring(codeStr.length - 2, codeStr.length), 10) + 31;
newString += String.fromCharCode(firstCharCode) + String.fromCharCode(lastCharCode);
} else {
newString += string.charAt(i);
}
}
return newString;
}
And I tied to translate on C#:
private string Decription(string encriptedText)
{
string ft = Regex.Escape(encriptedText);
string text = HttpUtility.UrlDecode(ft);
string newString = "";
for (int i = 0; i < text.Length; i++)
{
var ch = (int)text[i];
if(ch > 132)
{
var codeStr = Convert.ToString(ch, 10);
var firstCharCode = Convert.ToInt32(codeStr.Substring(0, codeStr.Length - 2), 10);
var lastCharCode = Convert.ToInt32(codeStr.Substring(codeStr.Length - 2, codeStr.Length), 10) + 31;
}
}
}
But how I can translate this row:
newString += String.fromCharCode(firstCharCode) + String.fromCharCode(lastCharCode);
Maybe do you know equivalent method to String.fromCharCode() on C# ?
Here you go:
public static void Main()
{
// from 97 to a
int i = 97;
Console.WriteLine(StringFromCharCode(97));
}
public static string StringFromCharCode(int code) => ((char)code).ToString();
Note that you may want to use a StringBuilder instead of concatening string in your case.
Related to Int to Char in C# (Read it. It includes a nice comment about cast vs Convert.ToChar)
You can simply use Convert.ToChar method, Convert.ToChar(97) will return a.
