 Format: Classroom, Online, Onsite | Durada: 5 dies

Descripció general

Descripció general

Aquest curs ensenya als desenvolupadors les habilitats de programació que es requereixen perquè creuen aplicacions Windows utilitzant el llenguatge C #. Durant els seus cinc dies a l’aula, els estudiants revisen els conceptes bàsics de l’estructura del programa C #, la sintaxi del llenguatge i els detalls de la implementació, i després consoliden els seus coneixements mentre construeixen una aplicació que incorpora diverses característiques de .NET Framework 4.5.

El curs introdueix moltes de les tècniques i tecnologies emprades per les modernes aplicacions d’escriptori i empresarials, incloent:

  • Creació de nous tipus de dades.
  • Maneig d’esdeveniments.
  • Programació de la interfície d’usuari.
  • Accés a una base de dades.
  • Ús de dades remotes.
  • Realització d’operacions de forma asíncrona.
  • Integració amb codi no administrat.
  • Creació d’atributs personalitzats.
  • Xifrat i desxifrat de dades.

Al final del curs, els estudiants han de deixar la classe amb un sòlid coneixement de C # i com usar-lo per a desenvolupar aplicacions .NET Framework 4.5.

At the end of this course students will be able to:

  • Describe the core syntax and features of C#.
  • Create and call methods, catch and handle exceptions, and describe the monitoring requirements of large-scale applications.
  • Implement the basic structure and essential elements of a typical desktop application.
  • Create classes, define and implement interfaces, and create and use generic collections.
  • Use inheritance to create a class hierarchy, extend a .NET Framework class, and create generic classes and methods.
  • Read and write data by using file input/output and streams, and serialize and deserialize data in different formats.
  • Create and use an entity data model for accessing a database and use LINQ to query and update data.
  • Use the types in the System.Net namespace and WCF Data Services to access and query remote data.
  • Build a graphical user interface by using XAML.
  • Improve the throughput and response time of applications by using tasks and asynchronous operations.
  • Integrate unmanaged libraries and dynamic components into a C# application.
  • Examine the metadata of types by using reflection, create and use custom attributes, generate code at runtime, and manage assembly versions.
  • Encrypt and decrypt data by using symmetric and asymmetric encryption.

This course is intended for experienced developers who already have programming experience in C, C++, JavaScript, Objective-C, Microsoft Visual Basic, or Java and understand the concepts of object-oriented programming.
This course is not designed for students who are new to programming; it is targeted at professional developers with at least one month of experience programming in an object-oriented environment.

Prerequisits

Prerequisits

Developers attending this course should already have gained some limited experience using C# to complete basic programming tasks. More specifically, students should have hands-on experience using C# that demonstrates their understanding of the following:
  • How to name, declare, initialize and assign values to variables within an application.
  • How to use:
    • arithmetic operators to perform arithmetic calculations involving one or more variables;
    • relational operators to test the relationship between two variables or expressions;
    • logical operators to combine expressions that contain relational operators.
  • How to create the code syntax for simple programming statements using C# language keywords and recognize syntax errors using the Visual Studio IDE.
  • How to create a simple branching structure using an IF statement.
  • How to create a simple looping structure using a For statement to iterate through a data array.
  • How to use the Visual Studio IDE to locate simple logic errors.
  • How to create a Function that accepts arguments (parameters and returns a value of a specified type.
  • How to design and build a simple user interface using standard controls from the Visual Studio toolbox.
  • How to connect to a SQL Server database and the basics of how to retrieve and store data.
  • How to sort data in a loop.
  • How to recognize the classes and methods used in a program.
