Making an anonymous function or method

Now, if you want, you can also do stuff that does not involve names. For example, you can enter the following next:

vals.ForEach(delegate (double x)

Next, we'll define the body, or the logic, between a set of curly braces. This is a nameless or anonymous one. For example, you can enter the following below this line (notice that you close with a parenthesis and semicolon after the closed curly brace):

{
    sampLabel.Text += "<br>" + Math.Pow(x, 3);
});

This one does something similar to the previous line. The only difference is that we are not calling anything named; we are just defining an anonymous function, a nameless function using a delegate keyword. This does accept one value, of course, the x value. Then you cube the x value; Math.Pow(x, 3) means, cube it and then display it on the label using += to append and <br> to push down a line, as usual.

Now, in the next stage, you can also do stuff such as the following, which is quite interesting:

Thread td = new Thread(delegate ())

Now, when you make an object of this type, you can also create a delegate. So, when you make this Thread object, you're also making an anonymous function. In other words, you're sending a piece of processing so that it runs on its own thread, and then you can stick in stuff such as the following:

{
List<double> arrs = new List<double>(new double[] { 1, 4, 5, 3, 53, 52 });arrs.Sort();arrs.ForEach(x => sampLabel.Text += $"<br>{x}");
}); 

Note again that here you close with a parenthesis and semicolon after the closing curly brace.
