C# WINFORM 上传图片 并保存在程序的根目录的某个文件夹中，代码如下：

private void btnUpLoad_Click(object sender, EventArgs e)

    {     

 openFileDialog1.Filter = "jpg files (*.jpg)|*.jpg";
            DialogResult dr = openFileDialog1.ShowDialog();
          

            if (dr == DialogResult.OK)
            {
              string  image = openFileDialog1.FileName;
              string  picpath = openFileDialog1.FileName;
              DateTime dt1 = new DateTime(1970, 1, 1);
              TimeSpan ts = DateTime.Now - dt1;
              long timeStamp = (long)ts.TotalMilliseconds;
              //string id = DateTime.Now.Millisecond.ToString();
              picPerson.Image = Image.FromFile(image);

              File.Copy(openFileDialog1.FileName, Application.StartupPath + "http://www.cnblogs.com/maxblog/admin/file://Image//" + timeStamp.ToString() + ".jpg");
            }
