查找界面上所有的TextBox控件，并给他赋初始值为 "aaa"
public void SetText(Control cc)
{
foreach (System.Windows.Forms.Control control in cc.Controls)
{
if (control is System.Windows.Forms.TextBox)
{
System.Windows.Forms.TextBox tb = (System.Windows.Forms.TextBox)control;
tb.Text = "aaa";
}
if (control.Controls.Count >0)
{
SetText(control);
}
}
}
调用方法:
private void Form2_Load(object sender, EventArgs e)
{
SetText(this);
}
效果图:
