求解一道C#程序题？

[k476496890]

已知一个接口Interface1，Interface2，Class1的代码如下
interface Interface1
{
int Add(int a ,int b ); //加法运算
int Mul（int a,int b ; //乘法运算
}
interface Interface2
{
string Name
{ get; set;}
}
class Class1
{
public void Hello(string name)
{ Console.WriteLine("你好:" + name);}
}
题目
（1）请通过一个新的类Class2，实现对上述两个接口和一个类的多重继承。
（2）并在Main方法中完成对Name的调用，对Add和Mul的调用，Hello方法的调用
（3）打印输出加法和乘法运算的值，可以自定义参数值，或键盘输入均可。

那就从两个接口继承，然后分别实现两个接口中的所有方法

    interface Interface1
    {
        int Add(int a, int b); //加法运算
        int Mul(int a, int b); //乘法运算
    }
    interface Interface2
    {
        string Name
        { get; set; }
    }
    class Class1
    {
        public void Hello(string name)
        { Console.WriteLine("你好:" + name); }
    }

    class Class2 : Class1, Interface1, Interface2
    {
        private string _name;
        public Class2(string name)
        {
            this._name = name;
        }

        public int Add(int a, int b)
        {
            return a + b;
        }

        public int Mul(int a, int b)
        {
            return a * b;
        }

        public string Name
        {
            get
            {
                return this._name;
            }
            set
            {
                this._name = value;
            }
        }
    }

    public class Client
    {
        public Client(string name, int a, int b)
        {
            Class2 c = new Class2(name);
            int add = c.Add(a, b);
            int mul = c.Mul(a, b);
            string outputName = c.Name;

            System.Diagnostics.Debug.WriteLine(add);
            System.Diagnostics.Debug.WriteLine(mul);
            System.Diagnostics.Debug.WriteLine(outputName);
        }
    }

应该是一道考试题吧
