CheckedComboBoxEdit 多选时，值与值之间会多出一个空格

测试代码：

 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("小红");
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：

 

对checkedComboBoxEdit的多值进行SQL查询时，查询中使用IN语句，IN里面第一个条件后面的所有条件的前面都会多出一个空格，导致查询不正确

需将空格去掉再传入SQL查询：

Replace(",","\',\'") 改为  Replace(", ","\',\'")
