使用Acrobat插件打印多个PDF (axAcroPDF1)

Question

我有一个windows应用程序，我想要在列表框中向打印机发送PDF的列表。浏览下面的代码，我可以看到*axAcroPDF1.LoadFile(s)正在加载我的应用程序中的每个文件，但Acrobat似乎只将lbPDFList列表框中的最后一项打印到打印机(例如：如果有4个PDF要打印，它总是只打印最后一个PDF)？

 int iListCounter = lbPDFList.Items.Count;
                for (int i=0; i < iListCounter; i++)
                {
                    String s = null;
                    lbPDFList.SetSelected(i,true);
                    s = lbPDFList.SelectedItem.ToString();
                    axAcroPDF1.LoadFile(s);
                    axAcroPDF1.Show();
                    axAcroPDF1.printAllFit(true);
                }

这是线程问题吗？

答案很简单！忽略axAcroPDF对象，只使用windows打印函数打印(使用循环中的以下代码打印每个PDF)：

 // start a new cmd process
        Process objP = new Process();
        objP.StartInfo.FileName = strFilePath;
        objP.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;         //Hide the window. 
    //!! Since the file name involves a nonexecutable file(.pdf file), including a verb to specify what action to take on the file. 
    //The action in our case is to "Print" a file in a selected printer.
    //!! Print the document in the printer selected in the PrintDialog !!//
    objP.StartInfo.Verb = "printto";
    objP.StartInfo.Arguments = "/p /h \"" + strFilePath + "\" \"" + pd.PrinterSettings.PrinterName + " \"";//pd.PrinterSettings.PrinterName;
    objP.StartInfo.CreateNoWindow = true;   //!! Don't create a Window. 
    objP.Start();                           //!! Start the process !!// 
    objP.CloseMainWindow();
