C# Webclient Stream download file from FTP to local storage

Question

I\'ve been downloading files from an FTP server via the WebClient object that the .NET namespace provides and then write the bytes to a actual file

Answer 1

Have you tried the following usage of WebClient class?

using (WebClient webClient = new WebClient())
{
    webClient.DownloadFile("url", "filePath");
}

Update

using (var client = new WebClient())
using (var stream = client.OpenRead("..."))
using (var file = File.Create("..."))
{
    stream.CopyTo(file);
}

If you want to download file explicitly using customized buffer size:

public static void DownloadFile(Uri address, string filePath)
{
    using (var client = new WebClient())
    using (var stream = client.OpenRead(address))
    using (var file = File.Create(filePath))
    {
        var buffer = new byte[4096];
        int bytesReceived;
        while ((bytesReceived = stream.Read(buffer, 0, buffer.Length)) != 0)
        {
            file.Write(buffer, 0, bytesReceived);
        }
    }
}
