namespace WindowsFormsApplication21
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void timer1_Tick(object sender, EventArgs e)
{
textBox1.Text = DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss");
try
{
FileInfo fi01 = new FileInfo("" + textBox2.Text);
fi01.CopyTo("" + textBox3.Text);
}
catch {
}
}
}
}
这里需要设置timer控件的值
效果
