From where you get that 300 value..?

Vulpes · Answer

What I don't understand is why the array needs to have a size of 62000 if you're only storing 300 values. Do you mean that you want to deliberately duplicate values? For example, all values between array[1] and array[7] inclusive will be "aaa"?

Hi Vulpes, Thank you for your reply, here my question is i declaring array with size 62000 but actually 300 values store in that array so i consumed more memory so instead of this suggest me some other way.

Vulpes · Answer

You typically use key/value pairs when you want to retrieve a value from a collection by it's key. The Hashtable and Dictionary classes do this automatically. If you only want to retrieve a value by its index, then an array or, if you're not sure how many values will be needed initially, an ArrayList or List should be used instead. It sounds like a Dictionary is what you need (for example a key of "ddd" would correspond to the integer 61000) but, TBH, I don't really understand what you're trying to do.
