Initializing IEnumerable<string> In C#

Ok, adding to the answers stated you might be also looking for

IEnumerable<string> m_oEnum = Enumerable.Empty<string>();

IEnumerable<string> m_oEnum = new string[]{};

IEnumerable<T> is an interface. You need to initiate with a concrete type (that implements IEnumerable<T>). Example:

IEnumerable<string> m_oEnum = new List<string>() { "1", "2", "3"};

As string[] implements IEnumerable

IEnumerable<string> m_oEnum = new string[] {"1","2","3"}

IEnumerable is just an interface and so can't be instantiated directly.

You need to create a concrete class (like a List)

IEnumerable<string> m_oEnum = new List<string>() { "1", "2", "3" };

you can then pass this to anything expecting an IEnumerable.
