Answer 1

IList tList =null;                tList = new List<ComboxItem> {
                new ComboxItem{ Name= "0", value = "--请选择--" },
                new ComboxItem{ Name= "1", value = "方案1" },
                new ComboxItem{ Name= "2", value = "方案2" }
            };
                        comboBox1.DataSource = tList;
                        comboBox1.DisplayMember = "value";
                        comboBox1.ValueMember = "Name";

Answer 2

我将代码更改为下面的就可以正确运行了，请看红色部分为更改的部分，也就是每次添加前都要new 一次discountclass,请高手解释为什么会这样呢？private void Form1_Load(object sender, EventArgs e)
        {
            comboBox1.DisplayMember = "Name";
            comboBox1.ValueMember = "Value";
            discountclass dc;            dc = new discountclass();
            dc.discounttype = "折扣A";
            dc.discount = 0;            comboBox1.Items.Add(new ComboxItem("方案1", dc));            dc = new discountclass();
            dc.discounttype = "折扣B";
            dc.discount = 1;            comboBox1.Items.Add(new ComboxItem("方案2", dc));
                    }
