CheckBoxList取值与初始化

CheckBoxList取值与初始化 很经典的代码

public static string SetChecked(CheckBoxList checkList,string selval,string separator)
         {
             selval = separator + selval + separator;        //例如："0,1,1,2,1"->",0,1,1,2,1,"
             for(int i=0; i<checkList.Items.Count; i++)
             {
                 checkList.Items[i].Selected = false;
                 string val = separator + checkList.Items[i].Value + separator;
                 if(selval.IndexOf(val)!=-1)
                 {
                     checkList.Items[i].Selected = true;
                     selval = selval.Replace(val,separator);        //然后从原来的值串中删除已经选中了的
                    if(selval == separator)        //selval的最后一项也被选中的话，此时经过Replace后，只会剩下一个分隔符
                    {        
                         selval += separator;        //添加一个分隔符
                    }
                 }
             }
             selval = selval.Substring(1,selval.Length-2);        //除去前后加的分割符号
            return selval;
         }

        /// <summary>
         /// 得到CheckBoxList中选中了的值
        /// </summary>
         /// <param name="checkList">CheckBoxList</param>
         /// <param name="separator">分割符号</param>
         /// <returns></returns>
         public static string GetChecked(CheckBoxList checkList, string separator)
         {
             string selval = "";
             for(int i=0;i<checkList.Items.Count;i++)
             {
                 if(checkList.Items[i].Selected)
                 {
                     selval += checkList.Items[i].Value + separator;
                 }
             }
             return selval;
         }
         protected void Button1_Click(object sender, EventArgs e)
         {
             string str;
             str = GetChecked(this.CheckBoxList1, ",");
             this.TextBox1.Text = str;
             SetChecked(this.CheckBoxList2, str, ",");
         }
