What is the difference between IEnumerator and IEnumerable?

An IEnumerator is a thing that can enumerate: it has the Current property and the MoveNext and Reset methods (which in . NET code you probably won’t call explicitly, though you could). An IEnumerable is a thing that can be enumerated…which simply means that it has a GetEnumerator method that returns an IEnumerator .

What is IEnumerator?

IEnumerator is an interface, which when implemented allows you to iterate through the list of controls. To implement it requires that you provide two methods – Reset to go back to the beginning of the list, and MoveNext to move forward, and Current to get the current item.

What is the difference between IEnumerable and IQueryable?

The principle difference is that IEnumerable will enumerate all of its elements all the time, while IQueryable will enumerate elements, or even do other things, based on a query. The query is an Expression (a data representation of .

What is IEnumerator interface in C#?

IEnumerable is an interface defining a single method GetEnumerator() that returns an IEnumerator interface. It is the base interface for all non-generic collections that can be enumerated. This works for read-only access to a collection that implements that IEnumerable can be used with a foreach statement.

What is difference between IQueryable and List in C#?

List is just an output format, and while it implements IEnumerable , is not directly related to querying. In other words, when you’re using IQueryable , you’re defining an expression that gets translated into something else.

What is an IEnumerator unity?

Conclusion: IEnumerator is a . NET type that is used to fragment large collection or files, or simply to pause an iteration. Coroutine is a Unity type that is used to create parallel actions returning a IEnumerator to do so.

Is IEnumerator an interface?

IEnumerator is the base interface for all non-generic enumerators. Its generic equivalent is the System.

Which is better LINQ or stored procedure?

Stored procedures are faster as compared to LINQ query since they have a predictable execution plan and can take the full advantage of SQL features. Hence, when a stored procedure is being executed next time, the database used the cached execution plan to execute that stored procedure.

Is IQueryable faster than list?

Here is a test that i have setup this evening. It was made to prove something different, but the outcome was not quite as i expected. I’m running a test with 10000 random queries on an IQueryable and while testing i found out that if i do the same on a List, my test is 20 times faster.

Can a coroutine have parameters?

The downside is that the string version has a higher runtime overhead to start the coroutine and you can pass only one parameter.
