我想从FTP服务器读取图像(TIF图像),然后查看它 我曾经从FTP服务器上读过这段代码:
//CREATE AN FTP REQUEST WITH THE DOMAIN AND CREDENTIALS
System.Net.FtpWebRequest tmpReq = (System.Net.FtpWebRequest)System.Net.FtpWebRequest.Create(filePath);
tmpReq.Credentials = new System.Net.NetworkCredential(userName, password);
//GET THE FTP RESPONSE
using (System.Net.WebResponse tmpRes = tmpReq.GetResponse())
{
//GET THE STREAM TO READ THE RESPONSE FROM
using (System.IO.Stream tmpStream = tmpRes.GetResponseStream())
{
//CREATE A TXT READER (COULD BE BINARY OR ANY OTHER TYPE YOU NEED)
using (System.IO.TextReader tmpReader = new System.IO.StreamReader(tmpStream))
{
//read and view image
}
}
}
}
我需要你的帮助如何将TIF图像转换为Jepg或其他类型,以及如何使用我的代码从FTP读取TIF
感谢

您可以使用Image类来执行转换。还要确保处置一次性资源,例如网络流:
class Program
{
static void Main()
{
var filePath = "ftp://example.com/foo.tif";
var request = WebRequest.Create(filePath);
request.Credentials = new NetworkCredential("user", "pass");
using (var response = request.GetResponse())
using (var stream = response.GetResponseStream())
using (var img = Image.FromStream(stream))
{
img.Save("foo.jpg", ImageFormat.Jpeg);
}
}
}
