how to get number of columns in an entity, like datatable?

I am new to entity framework.

I want to get the number of columns of an entity object just like the old Datatable technique. İs it possible ?

For example ,开发者_JS百科 in standart Nortwind Database , For the Customers table how can I get number of columns from Customers class derived from EntityObject;

Thanks in advance.

I think you can do this using reflection

PropertyInfo[] propertyInfos;
propertyInfos = typeof(MyClass).GetProperties();
var numberCol = propertyInfos.Length;

instead MyClass you should use your entity class
