Learning to Program with C#

All HOTT courses are available face-to-face, remote-live, on-demand or on-site at your facility. 

This hands on C# programming course provides an introduction to programming using the C# language. Students are introduced to the application development cycle, structure of programs, and specific language syntax. The course also contains "Thinking Like a Programmer" sections that provide students insight on how to develop common algorithms. 

The course covers console and file I/O, string and character manipulation, managing data using collections and fundamental object-oriented programming concepts. Error handling techniques are also emphasized. The course also introduces how to access databases using ADO.NET and illustrates how to build user interfaces using Windows Forms. Comprehensive hands on exercises are integrated throughout to reinforce learning and develop real competency.

Students Will Learn:

• Using Visual Studio to create C# applications 
• Working with the .NET data types 
• Creating variables with the proper scope and using operators to build complex expressions 
• Using control structures such as if, while and for 
• Using procedures to build complex applications 
• Designing and using classes 
• Using arrays and .NET collections 
• Throwing and trapping exceptions using the C# try and catch statements 
• Using ADO.NET to access databases 
• Working with files and directories 
• Building simple Windows Forms applications 
• Building and using derived classes 
• Defining and implementing interfaces 
• Performing advanced string manipulation

This class is intended for non-programmers. Students who already understand fundamental structured programming and object-oriented techniques should attend either Windows Forms 4.5 Programming Using C#, ASP.NET 4.5 Programming Using C# or Windows Presentation Foundation Programming Using C# instead of this more introductory course.

Course materials include student guide, hands-on lab manual and UBS flash drive containing examples and lab files. Students receive a certificate of completion at the end of class. 

Course Prerequisites: Familiarity with computers.

Prior to each class they examine the geographical location of the enrolled students and then select a venue that will provide most convenient overall access for the students. Classes are held in hotel conference rooms and exact location is determined 2 weeks prior to the course date.
