访问不同的类成员/属性的最佳方法是什么？

Question

我尝试使用字典，但是我使用了其他类型。

如果使用对象类型，则必须完成转换。

哪种方法是最好的方法？

当前

public class BaseMyClass
{

    public bool A;    
    public string Name;    
    public double Length;    
    public double Angle;    
    public double X1;    
    public double Y1;    
    public double X2;    
    public double Y2;    
    public double SumA;    
    public double SumB;

    public void Method1()    
    {    
        /* do Some */    
    }

    public void Method2()    
    {    
        /* do Some */    
    }

    public void Method3()    
    {    
        /* do Some */    
    }    
}

我想用这种方式。

public class BaseMyClass
{
    public bool A;
    public string Name;

    public void Method1() {
        /* do Some */
    }
    public void Method2() {
        /* do Some */
    }
    public void Method3() {
        /* do Some */
    }
}

public class MyA : BaseMyClass
{
    public double Length;
    public double Angle;

    public MyA()
    {
        Name = "MyA";
    }
}

public class MyB : BaseMyClass
{
    public double X1;
    public double Y1;

    public double X2;
    public double Y2;
    /* more */

    public MyB()
    {
        Name = "MyB";
    }
}

public class MyC : BaseMyClass {
    public double X1;
    public double Y1;

    public double SumA;
    public double SumB;

    public double Length;
    public MyC()
    {
        Name = "MyC";
    }
}
/* There are over 100 inherited classes. */

public class Processing
{
    public Processing()
    {
        List<BaseMyClass> list = new List<BaseMyClass>();
        /* Get file... or Socket ... Datas in List Random */

        // I can see the Name of the class.
        // However, members of the class are unknown.
        // What should I do ?
    }

}
