C# Programming videos | C# Part 11 - Foreach Loops

Posted by Andrew Gould on 21 November 2014


You can use a Foreach loop in C# to process a collection of objects, which is a tremendously useful thing to be able to do in an object-oriented language! This video explains how the foreach statement works and covers examples such as looping over the collection of controls in a form, looping over the open forms in your application and looping over the items in a list. You'll also see a comparison of the foreach loop and for loop, including a couple of limitations of the foreach statement. The video also covers how to write nested foreach loops.

Making a  video bigger

You can increase the size of your video to make it fill the screen like this:

Play your video (the icons shown won't appear until you do), then click on the full screen icon which appears as shown at its bottom right-hand corner.

 

When you've finished viewing a video in full screen mode, just press the Esc key to return to normal view.

Improving the quality of a video

To improve the quality of a video, first click on the Settings icon:

Make sure you're playing your video so that the icons shown appear, then click on this gear icon at the bottom right-hand corner.

 

Choose to change the video quality:

Video quality

Click on Quality as shown to bring up the submenu.

 

The higher the number you choose, the better will be your video quality (but the slower the connection speed):

Connection speed

Don't choose the HD option unless you have a fast enough connection speed to support it!

 

Is your Wise Owl speaking too slowly (or too quickly)?  You can also use the Settings menu above to change your playback speed.
