Indexers [modified]

Thanks for your input! In conclusion I must just not have been paying attention to the C# books I glossed over... Chris

Indexers are nice and commonly used in the .NET framework. If you think they would make sense in your project and simplify the usage of it, then go for indexers. regards

[c2423]

Yes, they simplify my project (in one place I even save an *entire line* of code :laugh: ) And I know that the framework contains them (for example when reading a SqlDataReader's values) However, my question was more along the lines of "do people generally know of their existance?" Anyway, thanks for your input - its good to know that its not an alien concept for people! Thanks, Chris

I think most people use them intuitively when accessing chars in strings, items in lists, values by key in dictionaries and lots of other stuff. Whenever the user knows that there's more data inside a class they either look for a GetXXX-Method or go for indexers without actually knowing that they just use "indexers". regards

Perhaps I wasn't being clear in my posts:

Which is why I want to use them for my class :) However there is a difference between understanding:

string x = "hello world";
char y = x[0];

And being able to write:

this[int indexno]
{
get { return something; }
}

What I wanted to know was are people familiar with how to add this functionality to a class, rather then can people use a class which already has this functionality.

This totally depends on the experience of the developer :confused: Experienced developers who have been programming with C# for quite a while will definitely know of their existence, while newcomers to C# probably miss them and go the GetXXX-way.

No problem. Man I sure missed an opportunity in replying to your other question!

I don't know, what's your address? I can look it up on Google Street View and tell you! :-D

When I first read "Indexer" I didn't know what you mean, but after seeing the example I realized you were talking about the [] operator. I think that almost every C++ developer might know that, as you can overload a lot of operators in C++ and it's something very useful. BTW, the GetXXX method, is a method that connects to the internet and downloads adult contents from a porn site. :laugh:

Again, not quite what I was looking for, but I think my question has been answered now anyway. Thanks, Chris

[c2423]

Thanks, exactly the answer I was looking for.
