代碼如下，記錄供以後備用

private void button1_Click(object sender, EventArgs e)
        {
            string str2 = Environment.CurrentDirectory;
            System.Diagnostics.ProcessStartInfo Info = new System.Diagnostics.ProcessStartInfo(str2+"\\template.xls");
            System.Diagnostics.Process Pro = System.Diagnostics.Process.Start(Info);
        }
