測試代碼：

 1 public partial class Form1 : Form
 2     {
 3         public Form1()
 4         {
 5             InitializeComponent();
 6         }
 7 
 8         private void Form1_Load(object sender, EventArgs e)
 9         {
10             List<string> list = new List<string>();
11             list.Add("
 
小明");
12             list.Add("小紅");
13             list.Add("小李");
14             this.checkedComboBoxEdit1.Properties.DataSource = list;
15         }
16 
17         private void checkedComboBoxEdit1_EditValueChanged(object sender, EventArgs e)
18         {
19             if (this.checkedComboBoxEdit1.Text != ""
 
)
20             {
21                 this.textEdit1.Text = this.checkedComboBoxEdit1.Text;
22                 this.textEdit2.Text = string.Format("select * from tableA where name in (‘{0}‘)", this.checkedComboBoxEdit1.Text).Replace(",","‘,‘");
23             }
24         }
25     }

效果：

對checkedComboBoxEdit的多值進行SQL查詢時，查詢中使用IN

需將空格去掉再傳入SQL查詢：

Replace(",","‘,‘") 改為  Replace(", ","‘,‘")

CheckedComboBoxEdit 多選時，值與值之間會多出一個空格
