自己写的操作记录的类，就是记录各种操作[原创]

网站的根目录下面创建一个文件夹 CaoZuoJiLu ，然后调用的时候 CaoZuo.JiLu("想记录的东西");
读取记录的时候：CaoZuo.ReadText(filepath);
如下：
if (!IsPostBack)
{
DropDownList1.Items.Insert(0, new ListItem("请选择要查看的记录", " "));
string path = Server.MapPath("~/CaoZuoJiLu");
DirectoryInfo di = new DirectoryInfo(path);
foreach (FileInfo fi in di.GetFiles())
{
ListItem li = new ListItem();
li.Value = fi.FullName;
li.Text = fi.Name;
DropDownList1.Items.Add(li);
}
}
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
//lbJilu.Text = File.ReadAllText(DropDownList1.SelectedValue,System.Text.Encoding.Default);
lbJilu.Text = CaoZuo.ReadText(DropDownList1.SelectedValue.ToString());
}
