有谁可以帮我解释一下这几行代码的作用和意思
请问在代码中char[] resultArr = new string('0', 0x10).ToCharArray(); 这句是什么意思?
请问在代码中OffByStart方法是什么意思,为什么要这样返回?
以下是代码:
public static string MachineToRegister(string machineCode)
{
if (machineCode.Length < 0x10)
{
return string.Empty;
}
string SoftName = AssemblyProduct;
int SnStrLen = SoftName.Length;
int McStrLen = machineCode.Length;
char[] resultArr = new string('0', 0x10).ToCharArray();
for (int i = 0; i < 0x10; i++)
{
char ch1 = machineCode[OffByStart(McStrLen, 9, i)];
char b = machineCode[OffByStart(McStrLen, 5, i)];
char c = machineCode[OffByStart(McStrLen, 2, i)];
char x1 = SoftName[OffByStart(SnStrLen, 8, i)];
char x2 = SoftName[OffByStart(SnStrLen, 1, i)];
long y = (long) ((((x1 * b) + x2) + c) % ((ulong) 10L));
resultArr[i] = GetLastHexOfInt(y);
}
string result = string.Empty;
foreach (char chr in resultArr)
{
result = result + chr.ToString();
}
return result;
}
public static int OffByStart(int strLen, int start, int offset)
{
int result = (start + offset) % strLen;
if (result == 0)
{
result = strLen - 1;
}
return result;
}
