如何把变量当方法来使用?????????
Button 是根据数据库中信息动态生成,在为其绑定事件时遇到如题困难,
请帮忙解决.
数据库信息如下:
代码:
private void createBtn()事件绑定 C#
{
List<BtnFun> lBtn;
using (PTE p = new PTE())
{
lBtn = (from btn in p.BtnFun select btn).ToList<BtnFun>();
}
TableRow tr = new TableRow();
foreach (BtnFun b in lBtn)
{
Button btn = new Button();
btn.ID = b.BtnID;
btn.Text = b.BtnText;
btn.Visible = (bool)b.BtnVisible;
// 这里如何把变量当方法绑定到Click事件中
//btn.Click += new EventHandler(b.btndelegate);
TableCell tc = new TableCell();
tc.Controls.Add(btn);
tr.Cells.Add(tc);
}
tbtn.Rows.Add(tr);
}
{
...
btn.Click += GetHandler(b.btndelegate);
}
private EventHandler GetHandler(string cmd)
{
switch(cmd.ToLower())
{
case "add": return this.add;
case "alter": return this.alter;
case "check": return this.check;
case "del": return this.del;
}
return null;
}
btn.Click += (EventHandler)Delegate.CreateDelegate(typeof(EventHandler), this, this.GetType().GetMethod(b.btndelegate, BindingFlags.Instance
[解决办法]
BindingFlags.Public
[解决办法]
BindingFlags.NonPublic));
