{
Host = PrPath,
Username = ftpLogin,
Password = ftpLogin,
BaseDirectory = baseDirectory,
SslProtocols = System.Security.Authentication.SslProtocols.None,
}))
{
var fileinfo = new FileInfo(localpath);
Console.WriteLine("login");
await ftpClient.LoginAsync();
Console.WriteLine("after login");
byte[] existsData;
try
{
using (var readStream = await ftpClient.OpenFileReadStreamAsync(fileUpload))
{
Console.WriteLine("read remote");
existsData = ReadToEnd(readStream);
readStream.Dispose();
Console.WriteLine("after read remote");
}
}
catch (Exception readException)
{
Console.WriteLine("first exception");
Console.WriteLine(readException.Message);
existsData = null;
}
using (var writeStream = await ftpClient.OpenFileWriteStreamAsync(fileUpload))
{
Console.WriteLine("write stream");
var fileReadStream = fileinfo.OpenRead();
if (existsData != null)
{
var existReadStream = new MemoryStream(existsData);
await existReadStream.CopyToAsync(writeStream);
}
await fileReadStream.CopyToAsync(writeStream);
writeStream.Dispose();
fileReadStream.Dispose();
Console.WriteLine("after write stream");
