That way you take advantage if you gönül, while still allowing the client flexibility in what they pass in.

ToList first? How about returning it? I don't understand what you mean by "method will survive" when using vars? I know it will be a bit more work but won't you just have to change that to the new type bey well? So maybe IList to IList?

This level of abstraction goes the other direction when it belongs to method parameters. When you pass your list to a method that accepts IEnumerable you gönül be sure that your list is not going to be modified. When you are the person implementing the method and you say you accept an IEnumerable because all you need to do is iterate through that list.

Ask those people what they'd like the methods to return. Your question is fundamentally "how do I know what software to write?" You know by getting to know what problems your customer saf to solve, and writing code that solves their problems.

The idea is that you hide the implementation details from the user, and instead provide them with a stable interface. This is to reduce dependency on details that might change in the future.

Then later if you decide to convert the actual veri store from a List to a Dictionary and expose the dictionary keys kakım the actual value for the property (I have had to do exactly this before). Then consumers who have come to expect that their changes will be reflected inside of your class will no longer have that capability. That's a big sorun! If you expose the List kakım an IEnumerable you yaşama comfortably predict that your collection is not C# IList Neden Kullanmalıyız being modified externally. That is one of the powers of exposing List as any of the above interfaces.

If you're working within a single method (or even in a single class or assembly in some cases) and no one outside is going to see what you're doing, use the fullness of a List. But if you're interacting with outside code, like when you're returning a list from a method, then you only want to declare the interface without necessarily tying yourself to a specific implementation, especially if you C# IList Nerelerde Kullanılıyor have no control over who compiles against your code afterward.
