[C#] Adding "partial" classes to the solution at runtime

2 Jun 2012 by Sergey Alexandrovich Kryukov

The concept of partial class has nothing to do with run time. The question makes no sense.To understand what partial declaration does, read carefully: http://msdn.microsoft.com/en-us/library/wa80x488.aspx[^].It looks like you do not really understand what a project build does, how the...

Using a Partial Class In C# to combine two fields into one Field. [Solved]

3 Jan 2013 by Sergey Alexandrovich Kryukov

First thing to understand: the "partial" feature of the classes has nothing to do with any functionality, whatsoever. This is nothing more than a way to write a class in two or more disjointed fragments of code, notably in different files. It has nothing to do with semantics, does not change the...

27 Jul 2011 by dasblinkenlight

No, it is not because the class is partial: the only thing the "partial" keyword does is letting you split a class (an interface, a struct) among two or more compilation units[^]. This is especially useful when parts of your class are generated by a tool.In other words, keyword "partial" is...
