• Access Modifiers (C# Programming Guide)
  • public, protected, internal, private
  • By default, classes and structs are "internal"
• C#'s const vs. readonly
  • const can't be static and is evaluated entirely at compile time
  • readonly can be static and is evaluated at runtime in declaration or ctor
• Application Class (System.Windows.Forms)
  • The application class provides the wrapper around the windows message loop

  • Methods are non-virtual by default but can be marked as such
  • C# does not have or allow a "throws" clause like Java

  • Class members that have no visibility specified have "private" visiblity

  • predefined aliases for "primitive" C# types. In the first link it says char is size 1, but I think it is really size 2.
• Method Parameters
  • "The params keyword lets you specify a method parameter that takes an argument where the number of arguments is variable."
  • This is the same as ... from Java 1.5
• Strings in C# - Properties of strings in C#
  • operators + and += are allowed
  • strings are immutable
  • operators == and != compare VALUES and not references
  • array notation to access single characters
  • @ quoting stops processing of escape characters
• Finding instance type of objects in C#
  • Use "is" operator: "if ( obj is double )"
• Generic Collections in C#
• Differences between events and delegates:
  • (From MSDN blogs) What's the difference between an event and a delegate?
    • "Put simply, an event gives more limited access than a delegate. If an event is made public, code in other classes can only add or remove handlers for that event; they can't necessarily fire it, find out all the handlers for it, or remove handlers they don't know about..."

• Using Calculated DataColumns in ADO.NET -- columns calculated from others and aggregate columns with ADO.NET and DataSets
• DataGridView.SelectionChanged Event (MSDN) -- has an example very much like my project
• How to: Use the DataGrid on the Pocket PC (MSDN) -- DataGrid is much less flexible in the compact framework.
