C# / .NET skills assessment, tests and coding exercises
The test focuses on C# and .NET Framework and is available in English and French. Questions are presented as coding exercises:
the candidate needs to write some code that achieves some objectives presented in the question.
The code is then executed and the result is analysed.
Individual questions or the overall test can have a time limit. When an overall time limit is set, the candidate can navigate between the various exercises.
Tests are built by selecting questions from a database of approximatively 60 questions dealing with the following subjects.
C# core language and functions
This category covers features at the core C# including data types, conditionnal operators, loop, mono multi-dimensionnal arrays, exceptions, collections, value and reference types. Knowledge of the C# syntax is also covered by this category.
Applied C# (files, databases...)
Cook book items and usual "real-life" problems : file management (read, copy, list directories), XML file handling, using a database (read and write from/to a DB), using regular expressions.
C# objects and design
Advanced objects and Object oriented concepts such as class desing (constructors, attributes, methods and properties, visibility) , inheritance (late binding, overriding, interfaces) and usual patterns (singleton, factory, ...).
Each test ends with an algorithmic question whose difficulty is in line with the rest of the test. In this question, the skill tested is not the knowledge of the language but rather the candidate's capacity to sole a mathematical problem using the language.
