How does it matter ? He's creating a list. I HATE when people tag ASP.NET, but their question is generic C#.

You're right, of course. I did not pay attention, thought it was about UI control... removed.

'Generic' means using generics, as in List<int>. With a generic List, Insert takes the index where you insert, just as you said. So, what is the issue ? If you were using ArrayList, the old non generic class, the same method exists. So, either there is no issue, or you need to explain better.

Sorry generic means it should be general way of inserting not using .Net framework list1.Insert().Because the range of data will go long like example 123,456,678,901,abc,def,ghi,jkl,................means it should be sorted to 123,abc,456,def,678,ghi,............

Sorry, sounds like a gibberish to me. Are you using List<> or not? If you're using List<>, it has well-defined set of operations, that's it. I don't understand how can it ever be a problem.

If you're not using the .NET framework, you're not using C#. Perhaps you need to edit your post to explain it better. Do you mean you want to write your own list class ? What class exactly are you using, and what is your issue ? do you mean you want your data to automatically sort according to some arbitrary rule that you will define ? you can define a sort method for that.

Sorry again .iam saying if i use list1.insert i should specify index that specific should not be used .index should not be specified iam having list<string> of 123, 456,789,..... iam adding string such as abc,def,ghi.... now the list is such that 123,456,789,abc,def,ghi...now i need to get 123,abc,456,def,789,ghi is there a possibility to insert in these way without using list.insert at specific index.i guess this comment is more readable
