Question

interface ISample
{
    int fncAdd();
}

class ibaseclass
{
    public int intF = 0, intS = 0;
    int Add()
    {
        return intF + intS;
    }
}
class iChild : ibaseclass, ISample
{
    int fncAdd()
    {
        int intTot = 0;
        ibaseclass obj = new ibaseclass();
        intTot = obj.intF;
        return intTot;
    }
}

I want to call ISample in static void Main(string[] args) but I dont know how to do that. Could you please tell me how?

Answer 1

An interface cannot be instantiated by itself. You can t just call an interface. You need to instantiate a class that actually implements the interface.

Interfaces don t and can t do anything by themselves.

例如:

ISample instance = new iChild(); // iChild implements ISample
instance.fncAdd();

以下问题对此提供了更详细的答案:

Answer 2

你们可以打上“召唤”的接口,或创建接口。

页: 1 页: 1 接口然后使用<代码>fncAdd。

Answer 3

你指的是:

static void Main(string[] args)
{
    ISample child = new iChild();
    child.fncAdd();
}

虽然正如其他人所言,法典似乎像它正确使用继承财产一样。
