  • Translating C# 3.0 query syntax for Linq-to-Objects, Part 2: SelectMany

    This is the second entry in a series demonstrating how C# 3.0 query syntax is translated into the underlying method calls for Linq-to-Objects, and that you can write your own versions of the Linq extension methods. In the first entry I outlined the types and collections I'd be using for this series, and looked at the translation of a simple Linq query with a single from clause to the Select extension...

This seems to have sparked quite a lot of debate about where the use of var is appropriate. The C# Reference documentation page (linked previously) suggests that: Overuse of var can make source code less readable for others. It is recommended to use...

  • Generating COM Interop types from IDL

    Recently I wrote a managed wrapper for BITS to use in blinkBox 's download manager application, which necessitates COM interop. This was made a little tricky due to the fact that BITS doesn't ship with primary interop assemblies or a type library; simply with an IDL interface definition file. However, using some command line tools it's quick to translate the IDL file into C# interop types...
