IEnumerable lt T gt  is an interface  You need to initiate with a concrete type  that implements IEnumerable lt T gt    Example   IEnumerable lt string gt  m oEnum   new List lt string gt       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 lt string gt  m oEnum   new List lt string gt       1    2    3       you can then pass this to anything expecting an IEnumerable

You can create a static method that will return desired IEnumerable like this    public static IEnumerable lt T gt  CreateEnumerable lt T gt  params T   values    gt      values    And then use it IEnumerable lt string gt  myStrings   CreateEnumerable  first item    second item     etc     Alternatively just do    IEnumerable lt string gt  myStrings   new      first item    second item

You cannot instantiate an interface - you must provide a concrete implementation of IEnumerable

As string   implements IEnumerable  IEnumerable lt string gt  m oEnum   new string     1   2   3

Ok  adding to the answers stated you might be also looking for  IEnumerable lt string gt  m oEnum   Enumerable Empty lt string gt       or  IEnumerable lt string gt  m oEnum   new string

IEnumerable is an interface  instead of looking for how to create an interface instance  create an implementation that matches the interface  create a list or an array  IEnumerable lt string gt  myStrings   new       quot first item quot    quot second item quot     IEnumerable lt string gt  myStrings   new List lt string gt     quot first item quot    quot second item quot
