Connect to network drive with user name and password

I really don't know the hidden process, but I use a webrequest, this way I'm able to pass the credentials, and it worked perfectly for me.

var ftpDownloadFile = WebRequest.Create("filePath");
ftpDownloadFile.Method = WebRequestMethods.Ftp.DownloadFile;
ftpDownloadFile.Credentials = new NetworkCredential("user", "pass");
using (var reader = (FtpWebResponse)ftpDownloadFile.GetResponse())
using (var responseStream = reader.GetResponseStream())
{
    var writeStream = new FileStream(Path.Combine(LocalStorage), FileMode.Create);
    const int length = 2048;
    var buffer = new Byte[length];
    if (responseStream != null)
    {
        var bytesRead = responseStream.Read(buffer, 0, length);
        while (bytesRead > 0)
        {
            writeStream.Write(buffer, 0, bytesRead);
            bytesRead = responseStream.Read(buffer, 0, length);
        }
    }
    reader.Close();
    writeStream.Close();
}

Use this code for Impersonation its tested in MVC.NET maybe for dot net core it required some change, If you want to dot net core let me know I will share.
