Object must implement IConvertible error when I have array of string in class

[pankajv82]

I am getting below error when my class has array of strings as a property.
"One or more errors occurred. (Object must implement IConvertible.)"

I also tried below but all lead to same error.
public IEnumerable Industry { get; set; }
public List Industry { get; set; }

class Company
{
public string[] Industry { get; set; }
}
