下面的代码在我后面的代码中用于上传 .pdf 文件，然后将其转换为 .swf(flash)。该 WriteToFile方法将pdf保存到服务器目录并在该Button1_Click方法中调用。在该Button1_Clicked方法中，我创建了一个进程来执行随 swftools 套件安装的 pdf2swf.exe，该套件将 pdf 转换为 flash 可读形式。
但是，下载的 pdf 没有转换为 swf，我想用它以不可下载的形式向我的网站用户显示。我已经知道如何显示 Flash 文件 (.swf)，但需要转换方面的帮助。
private void WriteToFile(string fileName)
{
// Create a file
string path = Server.MapPath("~/");
// string filename = FileUpload1.PostedFile.FileName;
int fileLength = FileUpload1.PostedFile.ContentLength;
byte[] imageBytes = new byte[fileLength];
FileUpload1.SaveAs(path + fileName);
}
protected void Button1_Click(object sender, EventArgs e)
{
int pageNumber = 1;
string inputfile = FileUpload1.FileName;
string filename = @"Sports_Events.pdf";
WriteToFile(FileUpload1.FileName);
string outputfile = @"pdfdoc.swf";
System.Diagnostics.Process pdf2swfprocess = new System.Diagnostics.Process();
// Process pdf2swfprocess = new Process();
pdf2swfprocess.StartInfo.UseShellExecute = false;
pdf2swfprocess.StartInfo.RedirectStandardOutput = true;
pdf2swfprocess.StartInfo.CreateNoWindow = true;
pdf2swfprocess.EnableRaisingEvents = false;
pdf2swfprocess.StartInfo.WorkingDirectory = HttpContext.Current.Server.MapPath("~");
pdf2swfprocess.StartInfo.RedirectStandardError = true;
pdf2swfprocess.StartInfo.FileName = HttpContext.Current.Server.MapPath("~/PDF2SWF/pdf2swf.exe");
//pdf2swfprocess.StartInfo.Arguments = inputfile + "-o" + outputfile;
pdf2swfprocess.StartInfo.Arguments = "\"" + HttpContext.Current.Server.MapPath("~/PDF2SWF/FONTS") + "\"" + " -p " + pageNumber + " " + filename + " -o " + filename + pageNumber + ".swf";
if (FileUpload1.HasFile)
{
try
{
pdf2swfprocess.Start();
pdf2swfprocess.WaitForExit();
pdf2swfprocess.Close();
}
catch (System.Exception)
{
Error1.Text = "Error converting file";
}
}
else
{
Error1.Text = "The selected file does not exist";
}
}
