Defining partial classes

Introduction

The definition of a type can be split over two or more source files. Each source file contains a class definition section, and all the different parts are combined once the application has been compiled.

Defining a partial class

To split the definition of a class, struct or interface, select the element in the explorer, and then associate the {CsPartial} tagged value (without parameters) to it in the auxiliary window (as shown below).

The {CsPartial} tagged value in the auxiliary window

Steps:

1. To associate the {CsPartial} tagged value to the element selected in the explorer, click on the "Associate a tagged value" icon in the auxiliary window and select it in the dropdown list.

2. The {CsPartial} tagged value then appears in the auxiliary window.

During code generation, Objecteering C# Developer will then position the new "partial" modifier just before the class, struct or interface keywords.

Note: Several rules concerning the definition of partial classes exist, and it is up to you to be sure that they are followed. Objecteering C# Developer carries out NO checks on this.
