如何遍历WinForm中自定义控件内的组件

Answer 1

一个递归方法取得页面上所有类型为textbox的控件，并对其清空，相信你看了后有所感悟。
private void Button1_Click(object sender, System.EventArgs e)
{
foreach (Control ctl in this.Controls)
{
this.txtClear(ctl);
}
}
private void txtClear(Control ctls)
{
if(ctls.HasControls())
{
foreach (Control ctl in ctls.Controls)
{
txtClear(ctl);
}
}
else
{
if (ctls.GetType().Name == "TextBox")
{
TextBox tb = new TextBox();
tb = (TextBox)this.FindControl(ctls.ID);
tb.Text = "";
}
}
}
