The name IEnumerator does not exist in current context
Solution 1
IEnumerator
is in System.Collections
and IEnumerator<T>
is in System.Collections.Generic
. So make sure you have the correct matching pair.
Solution 2
The name 'Enumerable' does not exist because It requires Linq which is available at Framework 4.0
And don't forget to use the libraries:
using System.Collections;
using System.Linq;
Solution 3
You have to put
using System.Collections;
at the top of your file.
Solution 4
I added using System.Collections and I was still getting error "The name 'Enumerable' does not exist in the current context". I added using System.Linq and the error disappeared.

This is the most annoying error I've had in a while. I want to make a simple loop to move my camera to another point in Unity, using C#.
I'm "using System.Collections.Generic", and IEnumerator even shows up in the suggestions when I start typing it, but as soon as I'm done, it goes red and has an error that reads "Assets/Scripts/NerworkManager.cs(190,9): error CS0246: The type or namespace name `IEnumerator' could not be found. Are you missing a using directive or an assembly reference?" in the console, and "error CS0103: The name IEnumerator does not exist in the current context" in the editor.
Here's my code:
IEnumerator LerpCam(Camera c, Vector3 target, float length){ float startTime = Time.time; while (Time.time < startTime + length) { c.transform.position = Vector3.Lerp (c.transform.position, target, Time.deltaTime); } yield return null; }
I have no idea what the problem is, and am able to use other things from the Generic collection without problems. Any help would be greatly appreciated.

IEnumerator
is the non-generic interface and resides inSystem.Collections
.

Var14ble almost 9 yearsThanks for that, can't believe I messed up something so simple, every other place was telling me I needed System.Collections.Generic... go figure.

GGG over 7 yearsNote that Enumerator =
System.Linq.Enumerator
and IEnumerator =System.Collections.IEnumerator
/IEnumerator<T> =System.Collections.Generic.IEnumerator<T>
.Enumerator
andIEnumerator
are not the same thing. One is the interface and the other is the implementation. -
hookenz almost 4 yearsThe using System.Linq worked for me, but the accepted answer didn't for some reason.
