This article discusses one of those programming topics that may be confusing at first but seems obvious once you know it.
As you know, C# enables you to overload the same method in a class with different arguments. But it’s also possible to overload a method with arguments that inherit from one another.
Many objects in .NET are stored in a hierarchy. For example: controls, files and folders, and anything you would normally display in a tree view. There are many different algorithms for finding the root of a hierarchy. Here is one of them:
Computerworld has published an in-depth interview with Microsoft’s leader of C# development, Anders Hejlsberg. A prominent Danish software engineer, Hejlsberg also wrote Turbo Pascal and was lead architect of the team that developed Delphi. Hejlsberg shared with Computerworld his thoughts on the development of C#, future programming trends, and his experiences putting out fires. Here is a brief excerpt:
It’s easy to determine if your C# application is 64-bit. Just check the Size property of IntPtr. If it’s 8, then your application is 64-bit. If it’s 4, then your application is 32-bit.
Here is a simple C# console program to demonstrate this:
The order of C# switch case statements in your code has no effect on performance.
How do you sort a C# array in descending or reverse order? A simple way is to sort the array in ascending order, then reverse it:
It’s not a trivial exercise to validate a file path on a Windows PC. There are a few special cases depending on the file system and operating subsystem (source):
It’s easy to display an RTF file — that was embedded as a resource in a C# program — in a Windows Form RichTextControl.
Sometimes it can be challenging to read the Details view in a ListView, especially if the rows are long. This article shows how to add shading to every second row to make a ListView easier to read.
It’s easy to extract an application’s own icon in C#:
form.Icon = Icon.ExtractAssociatedIcon( Application.ExecutablePath );
The ExtractAssociatedIcon static method on the Icon class (in System.Drawing) extracts the associated icon from any file. By supplying the Application.ExecutablePath (in System.Windows.Forms), you extract the application’s own icon.
