Compiler Hints
When compiling code, the C compiler must be able to locate information about the components that are being used. It will automatically search the file named mscorlib.dll , which contains the lowest-level .NET entities, such as data types. To use other components, the appropriate .dll for that component must be specified on the command line. For example, to use WinForms, the system.winforms.dll file must be specified as follows csc r system.winforms.dll myfile.cs The usual naming convention is...
Indexing with an Integer Index
A class that contains a database row might implement an indexer to access the columns in the row public DataValue string name, object data row.Add new DataValue Id, 5551212 row.Add new DataValue Name, Fred row.Add new DataValue Salary, 2355.23m DataRow row new DataRow row.Load DataValue val DataValue row 0 Console.WriteLine Column 0 0 , val.Data val.Data 12 set the ID The DataRow class has functions to load in a row of data, functions to save the data, and an indexer function to provide access...
Mark and Compact
The .NET garbage collector uses a Mark and Compact algorithm. When a collection is performed, the garbage collector starts at root objects including globals, statics, locals, and CPU registers , and finds all the objects that are referenced from those root objects. This collection of objects denotes the objects that are in use at the time of the collection, and therefore all other objects in the system are no longer needed. To finish the collection process, all the referenced objects are copied...
