C# Winform 对 comboBox1 用 this.comboBox1.SelectedValue.ToString() 取不到正确值

[tiger8000]

C# WinForm 窗体中 对 comboBox1 绑定数据如下：

this.comboBox1.DisplayMember = "DeparName";
this.comboBox1.ValueMember = "DeparCode";
this.comboBox1.DataSource = ds.Tables[0].DefaultView;
this.comboBox1.SelectedIndex = 0;


但是我在取值时：

string getDepart = this.comboBox1.Text; //能取到正确的值

string getDCode = this.comboBox1.SelectedValue.ToString(); //取不到正确值

存储到数据的值为：System.Data.DataRowView

这是怎么回事？晕了，弄了好关天，没找到什么原因

this.comboBox1.SelectedItem.ToString() 最好判断一下值是否为空或者NULL

数据库中数据全部有值，就是说，value 全部有值

知道咋回事了，自己粗心 this.comboBox1.ValueMember = "DeparCode"; 实际 this.comboBox1.ValueMember = "DepartCode"; 少写了一个 t

没有问题啊

private void Form1_Load(object sender, EventArgs e)
        {
            DataTable dt = CreateTPCommtbl();
            this.comboBox1.DisplayMember = "DeparName";
            this.comboBox1.ValueMember = "DeparCode";
            this.comboBox1.DataSource = dt.DefaultView;
            this.comboBox1.SelectedIndex = 0;
 
        }

        public DataTable CreateTPCommtbl()
        {
            DataTable dt = new DataTable();
            dt.TableName = "a";
            dt.Columns.Add("DeparName", typeof(System.String));
            dt.Columns.Add("DeparCode", typeof(System.Int32));
           
            for (Int32 i = 0;i< 5;i++)
            {
                DataRow nr = dt.NewRow();
                nr["DeparName"] = "aaa" + i.ToString ();
                nr["DeparCode"] = i;
                dt.Rows.Add(nr);
            }
            dt.AcceptChanges();
            return dt;
        }

        private void button1_Click(object sender, EventArgs e)
        {
            string getDepart = this.comboBox1.Text;
            string getDCode = this.comboBox1.SelectedValue.ToString();  
        }
