Introduction:

Lecture 9 covers a variety of topics related to C# programming. The lecture starts with a discussion on how to bind a list to a ListBox object by using the ItemsSource property and refreshing ListBox after modifying the bound list. This is followed by a discussion on how to use WebClient to download web pages quickly.

The lecture then moves on to discuss how to open a file as FileStream to write a bytes array to that file. It also covers when to use FileStream instead of StreamWriter or File.Write, File.*, etc. Additionally, the lecture talks about how and why we should use dispose of method if our object has that method.

The lecture then discusses how to use the Using statement and why to use the Using statement. It also covers how to use and utilize WPF tabs and how to add buttons to the tab menu to navigate between tabs. Furthermore, it discusses how to make a button an image button and how to add images as resources to the project and copy them to the output/debug folder.

Binding a List to a ListBox Object:

In C#, it is possible to bind a list to a ListBox object by using the ItemsSource property. This is a powerful feature that can save a lot of time and effort when working with large sets of data. Once the list is bound to the ListBox object, any changes made to the list will automatically be reflected in the ListBox object. However, it is important to refresh the ListBox after modifying the bound list to ensure that the changes are displayed correctly.

Using WebClient to Download Web Pages Quickly:

In C#, it is possible to use WebClient to download web pages quickly. WebClient is a powerful class that allows you to download data from the internet without having to write a lot of code. You can use WebClient to download HTML pages, images, and other types of data.

Opening a File as FileStream:

In C#, it is possible to open a file as FileStream to write a bytes array to that file. FileStream is a powerful class that allows you to write binary data to a file. FileStream is especially useful when you need to write large amounts of data to a file.

When to Use FileStream Instead of StreamWriter or File.Write:

In C#, it is important to know when to use FileStream instead of StreamWriter or File.Write. FileStream is useful when you need to write binary data to a file. StreamWriter is useful when you need to write text to a file. File.Write is useful when you need to write a byte array to a file.

Using Dispose Method:

In C#, it is important to use the dispose method if our object has that method. The dispose method is used to release resources used by an object. Failure to dispose of objects properly can result in memory leaks and other problems.

Using Using Statement:

In C#, it is important to use the Using statement. The Using statement is used to ensure that an object is disposed of properly.
