Static Method

Hi I have the following code

private string GetUser()
{
Decryption decrypt = new Decryption();
return (string) decrypt.DecodeText("agyL70eOPb=", key);
}

which calls this static method

public class Decryption
{
public static string DecodeText(string encrypted, string source)
{
string decrypted;
TripleDESCryptoServiceProvider des;
MD5CryptoServiceProvider hashmd5;
byte[] pwdhash, buff;
hashmd5 = new MD5CryptoServiceProvider();
pwdhash = hashmd5.ComputeHash(ASCIIEncoding.ASCII.GetBytes(source));
hashmd5 = null;
des = new TripleDESCryptoServiceProvider();
des.Key = pwdhash;
des.Mode = CipherMode.ECB;
buff = Convert.FromBase64String(encrypted);
decrypted = ASCIIEncoding.ASCII.GetString(des.CreateDecryptor
().TransformFinalBlock(buff, 0, buff.Length));
des = null;
return decrypted;
}
}


Is there a way to get rid of the 'new' line from the calling code

ie

private string GetUser()
{
return (string) DecodeText("agyL70eOPb=", key);
}

does not seem to work.
 
how about:

return (string) Decryption.DecodeText("agyL70eOPb=", key);

This will work ONLY if DecodeText is declared static (which it is in
your example).

Click to expand...

....and of course the cast to string is unneeded :) - sorry, forgot that.
 
used

return Library.Decryption.DecodeText("agyL70eOPb=", key);

but I get the compile error

An object reference is required for the nonstatic field, method, or property
'Library.Decryption.DecodeText(string, string)'

can't see why as the DecodeText is static?
 
This code will not compile in C# as it is illegal to call a static method through an object reference. You absolutely don't need the "new" line but you have to call through the type name, i.e.

private string GetUser()
{
return Decryption.DecodeText("agyL70eOPb=", key);
}
