From this it follows that your method implementation birey represent its local variables however you wish. The implementation details are not exposed. Leaving you free to change your code to something better without affecting the people calling your code.
I think that, ideally, the .NET Framework would include a static sorting method that accepts an IList, but the next best thing is to create your own extension method. It's derece too hard to create a couple of methods that will allow you to sort an IList kakım you would a List.

For instance I was switching one of my return types to a IList then I well I am probably just going to enumerate over them anyways lets just return an IEnumberable.
In addition to the older code that doesn't know about generics, there are also a lot of cases where you know you have a list

Object emanet be a T too. Doing this will save you headache if you decide to use a Stack or some other data structure further down the road. If all C# IList Kullanımı you need to do in the function is foreach through it, IEnumerable is really all you should be asking for.

Then later if you decide to convert the actual data C# IList Kullanımı store from a List to a Dictionary and expose the dictionary keys as 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 C# IList Kullanımı your class will no longer have that capability. That's a big problem! If you expose the List kakım an IEnumerable you C# IList Nedir can comfortably predict that your collection is hamiş being modified externally. That is one of the powers of exposing List birli C# IList Nedir 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 have no control over who compiles against your code afterward.
rajeshrajesh 39133 silver badges22 bronze badges 1 8 Excellent, clear answer, which I marked as helpful. However, I would add that for most developers, most of the time, the tiny difference in program size and performance is not worth worrying about: if in doubt, just use a List.
List derslikı tanılamamlanırken T tip bileğdavranışkenini tuzakır. Kısaca listenin içeriğinde hangi türden nesne yada değişçilikkenlerin olacağını belirler.
There is a complication though that dynamic kişi't see explicit implementations, so something güç implement IList and IList-of-T and yet still be completely unusable from dynamic.
