我使用 .NET 框架 4.
I use .NET framework 4.
在我的表单中,我有 41 个文本框.
In my form, I have 41 text boxes.
我已尝试使用此代码:
private void ClearTextBoxes()
{
Action<Control.ControlCollection> func = null;
func = (controls) =>
{
foreach (Control control in controls)
if (control is TextBox)
(control as TextBox).Clear();
else
func(control.Controls);
};
func(Controls);
}
还有这段代码:
private void ClearTextBoxes(Control.ControlCollection cc)
{
foreach (Control ctrl in cc)
{
TextBox tb = ctrl as TextBox;
if (tb != null)
tb.Text = String.Empty;
else
ClearTextBoxes(ctrl.Controls);
}
}
这对我仍然不起作用.
当我尝试使用此代码清除时 TextBoxName.Text = String.Empty;
文本框成功清除但一个文本框,仍然有 40 个文本框.
When I tried to clear with this code TextBoxName.Text = String.Empty;
the textbox success cleared but one textbox, still had 40 textbox again.
我该如何解决这个问题?
How do I solve this?
编辑
我输入了这个:
private void btnClear_Click(object sender, EventArgs e)
{
ClearAllText(this);
}
void ClearAllText(Control con)
{
foreach (Control c in con.Controls)
{
if (c is TextBox)
((TextBox)c).Clear();
else
ClearAllText(c);
}
}
但还是不行.

我使用了面板和拆分器.
I used panels and splitter.
void ClearAllText(Control con)
{
foreach (Control c in con.Controls)
{
if (c is TextBox)
((TextBox)c).Clear();
else
ClearAllText(c);
}
}
要使用上面的代码,只需这样做:
To use the above code, simply do this:
ClearAllText(this);
