我正在尝试制作一个小型个人屏幕捕获应用程序,我可以在其中按下快捷键并上传屏幕的完整屏幕截图。
我已设法将文件上传到我的网站,但我遇到的问题是,当您转到 URL 时,它显示为损坏的图像。
这是我的代码:
private void CaptureFullScreen()
{
string file = DateTime.Now.ToString("ddmmyyyyhhmmss") + ".jpg";
string file_store = screenshotDir + "\\" + file;
Rectangle bounds = Screen.GetBounds(Point.Empty);
using(Bitmap bitmap = new Bitmap(bounds.Width, bounds.Height))
{
using(Graphics g = Graphics.FromImage(bitmap))
{
g.CopyFromScreen(Point.Empty, Point.Empty, bounds.Size);
}
bitmap.Save(file_store, ImageFormat.Jpeg);
}
//System.Diagnostics.Process.Start(file);
ShowBalloonTip("Uploading...", "Screen Capture is being uploaded", ToolTipIcon.Info, 1000);
FtpFileUpload(file_store, file);
}
private void FtpFileUpload(string file_store, string file_name)
{
try
{
FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://passion4web.co.uk/www/apps/imgcap/" + file_name);
request.Method = WebRequestMethods.Ftp.UploadFile;
request.Credentials = new NetworkCredential("username", "password");
StreamReader strRead = new StreamReader(file_store);
byte[] fileContents = Encoding.UTF8.GetBytes(strRead.ReadToEnd());
strRead.Close();
request.ContentLength = fileContents.Length;
Stream reqStream = request.GetRequestStream();
reqStream.Write(fileContents, 0, fileContents.Length);
reqStream.Close();
FtpWebResponse response = (FtpWebResponse)request.GetResponse();
string url = "http://passion4web.co.uk/apps/imgcap/" + file_name;
string resp = response.StatusDescription;
ShowBalloonTip("Screenshot uploaded", "Click this balloon to open", ToolTipIcon.Info, 5000, url);
response.Close();
}
catch (Exception ex)
{
//Ignore this - used for debugging
MessageBox.Show(ex.ToString(),"Upload error");
MessageBox.Show(file_name + Environment.NewLine + file_store, "Filename, Filestore");
}
}
这是一个示例: 屏幕截图
有任何想法吗?
