winform实现动态多选框

1. 创建一个流式布局面板控件

flowchatLayoutPanel

2. 将API传过来的datatable遍历，创建复选框，将datatable中的数据填充复选框

  for (int i = 0; i < dtJson.Rows.Count; i++)
                {
                    CheckBox processCB = new CheckBox();
                    processCB.Text = dtJson.Rows[i]["ITEM_NAME"].ToString();
                    processCB.Tag = dtJson.Rows[i]["ITEM_NO"].ToString();
                    processCB.AutoSize = true;
                    processCB.Font = new Font("微软雅黑", 13F);
                    processCB.Margin = new Padding(20, 2, 0, 0);
                   this.ProcessPanel.Controls.Add(processCB);
                }

3. 遍历复选框，将复选框已选的值存入datatable（也可以使用Dictionary<string, string>存储）中，传入API

			//创建局部变量datatable
			DataTable partsDt = new DataTable();
			//给局部变量添加两列
            DataColumn dc1 = new DataColumn("part_no", Type.GetType("System.String"));
            DataColumn dc2 = new DataColumn("part_name", Type.GetType("System.String"));
            partsDt.Columns.Add(dc1);
            partsDt.Columns.Add(dc2);
			//遍历复选框中的值，将已选的值储存在datatable中
            foreach (Control c in this.ProcessPanel.Controls)
            {
                if (c is CheckBox)
                {
                    CheckBox ck = c as CheckBox;
                    if (ck.Checked)
                    {
                        DataRow dr = partsDt.NewRow();
                        dr["part_no"] = ck.Tag.ToString();
                        dr["part_name"] = ck.Text;
                        partsDt.Rows.Add(dr);
                    }
                }
           }
