調(diào)用實(shí)例：
下載（不需要帶iis部分的路徑）：
FileUpDownload.FtpServerIP = "192.168.1.1";
FileUpDownload.FtpUserID = "ftpTest001";
FileUpDownload.FtpPassword = "aaaaaa";
FileUpDownload.FtpDownload("Beyond Compare（綠色免安裝）.zip",
Application.StartupPath + "/downloads/crm2.ra6", false);
上傳（不需要帶iis部分的路徑）：
OpenFileDialog op = new OpenFileDialog();
op.InitialDirectory = Application.StartupPath;
op.RestoreDirectory = true;
op.Filter = "壓縮文件(*.zip)|*.zip|壓縮文件(*.rar)|*.rar|所有文件(*.*)|*.*";
if (op.ShowDialog() == DialogResult.OK)
{
string aa = op.FileName;
FileUpDownload.FtpServerIP = "192.168.1.1";
FileUpDownload.FtpUserID = "ftpTest001";
FileUpDownload.FtpPassword = "aaaaaa";
//全路徑
FileUpDownload.FtpUploadFile(aa);
}
