我已将代码简化为此
@H_301_2@internal class Program
{
private static void Main(string[] args)
{
Child d = new Child();
int i = 100;
d.AddToTotal(i);
Console.ReadKey();
}
private class Parent
{
public virtual void AddToTotal(int x)
{
Console.WriteLine("Parent.AddToTotal(int)");
}
}
private class Child : Parent
{
public override void AddToTotal(int number)
{
Console.WriteLine("Child.AddToTotal(int)");
}
public void AddToTotal(double currency)
{
Console.WriteLine("Child.AddToTotal(double)");
}
}
}
问题是这个电话
@H_301_2@public void AddToTotal(double currency)虽然我用int调用它,它应该使用
@H_301_2@public override void AddToTotal(int number)使用父级返回预期结果.
@H_301_2@Parent d = new Child(); int i = 100; d.AddToTotal(i);更新：
感谢@Jan和@azyberezovsky将我指向specification.我已经向基类添加了一个虚拟空方法,以便现在解决这个问题.
