C#

class Program
{
    static void Main(string[] args)
    {

        string str = "Hello";


        for (int i = 0; i < str.Length; i++)
        {
            Console.WriteLine(str[i]);

        }
    }
}

In the above program, I have used Length property, I dont want to use string Length property, i want to create a similar property like Length. What is the logic and how can i achieve it?

That doesn't make sense. It's a property because it's, well, a property of a string instance, how long the string is.

Property of Length? Of what? and why would you want to do this?

Thanks. Can i see in .net how this 'Length' property is coded?

can i make the same program without using Length property?

You can but it's not what a normal piece of Property code would look like and really isn't going to do you any good at all.

Reference Source[^]

Learn what Properties are and how they are used before you go spelunking through the .NET Reference Source.

You can read about properties anywhere. What's the problem? What do you want to achieve?
What have you tried so far?

You can download the source code and see it, but you don't need to bother so much.
Better read about properties in a regular text book.
Your request about "make the same without...", it simply makes no sense. Read the book first.

You should read a book on C# before writing your first program.

Don't re-invent the wheel.

Properties are very basic stuff and you'll be able to read up on that in any C#-tutorial on the web or in any introductory book on C#. Here's a (legal) free PDF book on C#: Introduction to Programming with C#[^]

However, I'll add that it'll depend on whether you want to add a property to a class that you wrote yourself or to a class from the .Net Framework. The latter case is not possible because there are no true extension properties in C# yet. Only workarounds that achieve somewhat the same goal but don't work the same way. You'll find them by googling for "C# extension properties".
