Do you mean create an index?

If so, you have you can use a Stored Procedure (or SQL statement) that creates an index on the table/columns you want. This reference[^] will give you a whole slew of options because you will need to customize the index to suit your needs.

But the question I have to ask is why do you need to do this? Indexes are not something that you should toy with "on the fly". They grow, massively in some cases, for a reason and that's to cut down on seek times afterwards.

This is what you are looking for then reference. But beware, this will be discontinued in the next edition of SQL server.

If this answers your question, don't forget to mark the question as answered. But I'm still pretty certain you should not be doing something like this at runtime.

sorry friend your answer is correct but please send me a c# code reference

That is C#. SQL-DMO (Database Management Object) are a high level .NET library to access high level functions. I'm almost 100% sure that there is no way to alter indexes from C# without doing it this way. This might help you (CP Article).
