6 C# Features You Probably Didn’t Know Exist

Who would’ve thought these work.

1. Tweaking File Paths

Okay, so the first thing I found out is about file paths in C#.

You can actually use the division symbol to work with them. I tried this out, and it was surprising to see how you can kind of ‘split’ the path in your code using this symbol. It’s a bit out of the ordinary, but it’s neat to see it work.

public class FilePath
{
    private string path;

    public FilePath(string initialPath)
    {
        path = initialPath;
    }

    public static FilePath operator /(FilePath filePath, string addition)
    {
        return new FilePath(filePath.path + "/" + addition);
    }

    public override string ToString()
    {
        return path;
    }
}

// Usage
var basePath = new FilePath("C:/Users/YourUser");
var fullPath = basePath / "Documents" / "test.txt";
Console.WriteLine(fullPath);

2. The ‘Await Anything’ Trick

Next, there’s this thing where you can make C# wait for just about anything. It sounds a bit weird, right? But it’s true.

By adding something called a GetAwaiter method, you can make the code pause for anything – even a number! I gave this a go, and it was pretty wild to see the code pause just…
