c# - 将文件从字符串或流上传到FTP服务器

我正在尝试在FTP服务器上创建文件，但我所拥有的只是字符串或数据流以及应使用其创建的文件名。是否可以通过流或字符串在服务器上创建文件(我没有创建本地文件的权限)？

string location = "ftp://xxx.xxx.xxx.xxx:21/TestLocation/Test.csv";

WebRequest ftpRequest = WebRequest.Create(location);
ftpRequest.Method = WebRequestMethods.Ftp.UploadFile;
ftpRequest.Credentials = new NetworkCredential(userName, password);

string data = csv.getData();
MemoryStream stream = csv.getStream();

//Magic

using (var response = (FtpWebResponse)ftpRequest.GetResponse()) { }

最佳答案

只需将您的流复制到FTP请求流:

Stream requestStream = ftpRequest.GetRequestStream();
stream.CopyTo(requestStream);
requestStream.Close();

对于字符串(假设内容是文本):

byte[] bytes = Encoding.UTF8.GetBytes(data);

using (Stream requestStream = request.GetRequestStream())
{
    requestStream.Write(bytes, 0, bytes.Length);
}

甚至更好地使用 StreamWriter :

using (Stream requestStream = request.GetRequestStream())
using (StreamWriter writer = new StreamWriter(requestStream, Encoding.UTF8))
{
    writer.Write(data);
}

如果内容是文本，则应使用文本模式:

request.UseBinary = false;
