Moq, SetupGet, Mocking a property

Question

Answer 1

ColumnNames is a property of type List so when you are setting up you need to pass a List in the Returns call as an argument (or a func which return a List)

But with this line you are trying to return just a string

input.SetupGet(x => x.ColumnNames).Returns(temp[0]);

which is causing the exception.

Change it to return whole list:

input.SetupGet(x => x.ColumnNames).Returns(temp);
