Escape Characters
13.11.2007 22:24:48 - Filed under : C# | Asp.net
When you want to put a line return, or a single or double quote into a string. The C# processor throws an error. So you have to use escape characters to let the processor know what you are doing.

Writing double quote :
builder = "<div id=\"dropmsg" + i + "\" class=\"dropcontent\" subject=\"" + var.contentheader + "\">";

View Oracle GUID in .NET
23.08.2006 10:08:14 - Filed under : C# | Oracle
Oracle GUID appearance is different in .NET.  But in action this conversation implemented automatically. If you want to see oracle GUID (as you can see in oracle) regularly you should use a function like this.
public string ByteToRawString (byte [] byteArray)
        {
            string str="" ;
            for (int i = 0; i < byteArray.Length   ; i++)
            {
                str+=String.Format("{0:x2}", byteArray[i]);
            }
            return str.ToUpper();
        }
