调用方式：
FrmUploadFile frmUp = new FrmUploadFile(Openfile.FileName);
show 或者 frmUp.ShowDialog()==OK都可以。为了界面可以展示开，定时2s开始下载或者上传数据。
另外其他的使用方法：
using (WebClient client = new WebClient())
{
string fileName = openFileDialog1.FileName;
Uri url_upload = new Uri("change recive remote url");
NameValueCollection nvc = new NameValueCollection();
// data insert
// nvc.Add("userid", "user01");
// nvc.Add("workid", "work01");
client.QueryString = nvc;
client.UploadFileCompleted += (s, e1) =>
{
string msg;
btn_Selectfile.Enabled = true;
btn_Upload.Enabled = true;
msg = Encoding.UTF8.GetString(e1.Result);
MessageBox.Show(msg);
};
client.UploadProgressChanged += (s, e1) =>
{
double BytesSent = e1.BytesSent;
double TotalBytesToSend = e1.TotalBytesToSend;
int percent = (int)((BytesSent / TotalBytesToSend) * 100.0);
prog_Upload.Value = percent;
lbl_Percent.Text = percent + "%";
};
client.UploadFileAsync(url_upload, fileName);
client.Dispose();
}
FTP上传方法：
using (var request = new WebClient())
{
request.Credentials = DefaultCredentials;
try
{
request.UploadFileAsync(new Uri($"ftp://{ServerAddress}/{outfilepath}"), "STOR", infilepath);
return true;
}
catch (WebException ex)
{
Logger.Write(ex.Message);
return false;
}
}
