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:
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 DataGridView is a powerful grid control included in the .NET Framework. One function missing, however, is the ability to hide the current selection when the DataGridView control is not focused. What the DataGridView class needs is a HideSelection property, similar to the ListView and TextBox. But the .NET designers have not included this capability in the DataGridView class.
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.
Sadly there is no built-in function in System.IO that will copy a folder and its contents. Following is a simple recursive algorithm that copies a folder, its sub-folders and files, creating the destination folder if needed. For simplicity, there is no error handling; an exception will throw if anything goes wrong, such as null or invalid paths or if the destination files already exist.
