Question

I’m using an API that has an object that returns IEnumerable<T>, so something like Object.GetEnum<T>.

I have a method that within it will call GetEnum but I want to add to the method’s parameters the ability to pass the parameter type. So for example I want to do:

private void myMethod(apiClass???  apiclass)   { IEnumerable< itemType > enumX = ObjectGetEnum< itemType > } private void Main() {     myMethod(apiClass1);     myMethod(apiClass2); } 

So as above I don’t know what the parameter type should be in myMethod or how to write the code that gets the enumerator. I tried passing “apiClass”, the class which apiClass1 and apiClass2 inherit from. But then got stuck there on what to do…and I don’t think that really work anyways.

So I’m not sure if I just don’t know how in C# to do this, or if it is even possible, …. or perhaps I’m missing something in the API (or the API is missing something to facilitate this).

Thanks FKC

Okay, I’m going to take a stab at this, although I’d like the question to be clarified. I suspect you just need to make the method generic:

private void MyMethod<TItem>() where TItem : ApiClass {     IEnumerable<TItem> enumX = ObjectGetEnum<TItem>(); }  private static void Main() {     MyMethod<ApiClass1>();     MyMethod<ApiClass2>(); }
