Process Checksum

[JohnnyBlazer]

Hello guys,

Does someone know how I can get a checksum (in C#) of a running process and probably locked, like svchost or a program in use, like FireFox? I get access denied when trying to open it using this method:

protected string GetMD5HashFromFile(string fileName)
{
FileStream file = new FileStream(fileName, FileMode.Open);
MD5 md5 = new MD5CryptoServiceProvider();
byte[] retVal = md5.ComputeHash(file);
file.Close();

ASCIIEncoding enc = new ASCIIEncoding();
return enc.GetString(retVal);
}

Source: http://sharpertutorials.com/calculate-md5-checksum-file/

AntiVirus programs compare file hashes to check the files legitimacy, so it must be possible.

Thanks in advance.

Regards,
John

Try this... It works for me. Though the encoding was all messed up for me on the hash, but you're not trying to read these checksums i assume right?


FileStream file = new FileInfo(fileName).OpenRead();
