Hi .... everyone !
I have Java -> C# Programming Problem , plz help !
it's delay 1 week to solve it , plz help ......
[code cpp]
using System;
using System.Collections.Generic;
using System.Globalization;
using System.IO;
using System.Linq;
using System.Text;


public class MyGen
{
private const string LL = "keygen";
public virtual string getSerial(string userId, string licenseNum)
{
DateTime cal = new DateTime();
cal.Add(1, 3); // This is Java Code
cal.Add(6, -1); // This is Java Code
NumberFormat nf = new java.text.DecimalFormat("000"); // This is Java Code
licenseNum = nf.format(Convert.ToInt32(licenseNum)); // This is Java Code
string verTime = new StringBuilder("-").Append(new java.text.SimpleDateFormat("yyMMdd").format(cal.getTime())).Append("0").ToString(); // This is Java Code
string type = "YE3MP-";
string need = new StringBuilder(userId.Substring(0, 1)).Append(type).Append("300").Append(licenseNum).Append(verTime).ToString();
string dx = new StringBuilder(need).Append(LL).Append(userId).ToString();
int suf = this.decode(dx);
string code = new StringBuilder(need).Append(Convert.ToString(suf)).ToString();
return this.change(code);
}
private int decode(string s)
{
int i;
char[] ac;
int j;
int k;

while (j < k)
{

j ;
}
