Question

winform 遍历窗体中所有用户控件中的textbox 然后赋为空值 急啊！！帮帮忙，，

Answer 1

最好用迭代，form里可能用别的容器控件，如panel，里面的可能也有textbox.

追问

代码？？方便给点吧？谢了。。。

追答

public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void Form1_Load(object sender, EventArgs e)
{
foreach (Control c in this.Controls)
{
CheckTextBox(c);
}
}

private void SetTextBoxValue(TextBox tb,string val)
{
tb.Text = val;
}

private void CheckTextBox(Control con)
{
if (!con.HasChildren)
{
if (con is TextBox)//是不是TextBox
{
SetTextBoxValue((TextBox)con, "Test Success");
return;
}
}
else
{
foreach (Control child in con.Controls)
{
CheckTextBox(child);
}
}
}

}

建议你看懂了自己在写一遍

Answer 2

foreach (Control c in Controls)
{
if (c.HasChildren)
{
foreach (Control cc in c.Controls)
{

if (cc is TextBox)
{
((TextBox)cc).TExt= "";
}
}
}

}
