A PHP compatible MD5 function in c#
By Justin Silverton
The following is a function written in c# that will return a PHP compatible MD5 hash of a file, given the name. The equivalent function in PHP is md5_file().
public string MD5Hash( string sFilePath )
{
try
{
MD5CryptoServiceProvider md5Provider
= new MD5CryptoServiceProvider();
FileStream fs
= new FileStream(sFilePath, FileMode.Open, FileAccess.Read);
Byte[] hashCode
= md5Provider.ComputeHash(fs);
string ret = "";
foreach (byte a in hashCode)
{
if (a<16)
ret += "0" + a.ToString ("x");
else
ret += a.ToString ("x");
}
fs.Close();
return ret;
}
catch( Exception ex )
{
throw ex;
}
}

The capability hasn’t completed yet, because the original function has an optional raw_output boolean parameter. Any way it’s good example of usage md5 api in c#. I’m interesting why you hasn’t wrote anything about c# before and write now?
Thanks for the comment/suggestion.
I have been using c# on a couple of personal projects in the past year and I recently had to create a windows application that communicated with a php web service (which also needed the md5_file() functions to match on both sides).
I hope to see other news about c# here, at least one reader is guaranteed for it
