Multi Line Strings
Use the '@' character before the string to create a verbatim string literal:
String sTemp = @"This string is on multiple lines";
You can have the string be on multiple lines
You don't need to escape characters other than " (which you do by using "" 2 x double quotes), so no need for " C:\\some_directory"
You can't have comments within it
Convert Value To String
int Value; Value = 100; mytextbox.text = Value.ToString();
