我创建了一个类，但是当我尝试使用
访问它时Dim obj As New FabSalesDB.BusinessLayer.DayEnd
编译器无法在FabSalesDB.BusinessLayer中找到它，但它可以找到其他类。可能是什么原因？
namespace FabSalesDB.BusinessLayer
{
public class DayEnd : BusinessObjectBase
{
public enum DayEndFields
{
date,
CashTaken,
CardsTaken,
CashRegistered,

CardVariance,

R100,
R50,
R20,
R10,
R5,
R2,
R1,
c50,
c20,
c10,
c5,
c1

答案 0 :(得分：0)
如果你想将它与Class Var = new Class（）一起使用，你的类应该有一个构造函数;
构造函数应该是：
public DayEnd ()
{
//
// TODO: Add constructor logic here
//
}
