To not show your passwords in plain text on a propertygrid, just use the PasswordPropertyText attribute:

[DisplayName("Password"), Category("Authentication"), PasswordPropertyText(true)] 
public string Password 
{ 
   … 
}

    private byte[] ImageToByteArray(Image img) 
    { 
        // stream to save the image to byte array 
        Stream ms = new MemoryStream(); 
        img.Save(ms, img.RawFormat); 

        // read to end 
        byte[] imgBytes = new byte[ms.Length-1]; 
        ms.Position = 0; 
        ms.Read(imgBytes, 0, imgBytes.Length); 
        ms.Close(); 

        return imgBytes; 
    }

Если в сборку включена отладочная информация, то:

string currentFile = new System.Diagnostics.StackTrace(true).GetFrame(0).GetFileName(); 
int currentLine = new System.Diagnostics.StackTrace(true).GetFrame(0).GetFileLineNumber();
