Hi
Strange requirement. Virus? :D . Something like
class Program
{
private static byte[] exe;
static string GetFileName()
{
return
Path.Combine(AppDomain.CurrentDomain.SetupInformation.ApplicationBase,
"ConsoleApplication5.exe");
}
static void Read(string[] args)
{
using (var fs = new FileStream(GetFileName(),
FileMode.Open, FileAccess.Read))
{
var ms = new MemoryStream();
int bl = 1024;
byte[] buffer = new byte[bl];
int bytesReaded = fs.Read(buffer, 0, bl);
while (bytesReaded>0)
{
ms.Write(buffer, 0, bytesReaded);
bytesReaded = fs.Read(buffer, 0, bl);
}
ms.Position = 0;
exe = ms.ToArray();
ms.Close();
fs.Close();
}
}
static void WriteExe()
{
var fileName = GetFileName();
if (File.Exists(fileName))
return;
using (var fs = new FileStream(fileName, FileMode.Create,
FileAccess.Write))
{
fs.Write(exe, 0, exe.Length);
fs.Close();
}
}
}
