我需要一些JS代码翻译到C#的帮助。JS代码:
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;
}我在C#上绑定了翻译:
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;
}
}
}但我如何翻译这行:
newString += String.fromCharCode(firstCharCode) + String.fromCharCode(lastCharCode);也许你知道C#上String.fromCharCode()的等价方法?

这就是了:
public static void Main()
{
// from 97 to a
int i = 97;
Console.WriteLine(StringFromCharCode(97));
}
public static string StringFromCharCode(int code) => ((char)code).ToString();请注意,在本例中,您可能希望使用StringBuilder而不是连接string。
与Int to Char in C#相关(请阅读。它包含了一个关于cast和Convert.ToChar的很好的评论)

您可以简单地使用Convert.ToChar方法,Convert.ToChar(97)将返回a。
