Question

我从未在C＃或视觉工作室编程，我认为开始的唯一方法是潜入并体验伤害和痛苦并解决出现的问题。请原谅我的补救问题和缺乏经验。

我在下面的代码中打开了一个应用程序，如果它尚未打开。还返回进程ID（以防万一我需要它）一旦应用程序打开，代码集2就会将文档打印到默认打印机，该打印机在打开应用程序之前设置。

using System;
using System.Diagnostics;

namespace ImageIT.PreFlight
{
    public class AppCheck
    {
        public int IsAppOpen (string appCheck)
        {
            Console.WriteLine("We are in APPCHECK");
            var appToStart = Process.GetProcessesByName(appCheck);
            Process[] processlist = Process.GetProcesses();
            var appID = 0;

            if (appToStart.Length == 0)
            {
                ProcessStartInfo startInfo = new ProcessStartInfo
                {
                    FileName = appCheck,
                    CreateNoWindow = true,
                    Arguments = "/q /n /x",
                    WindowStyle = ProcessWindowStyle.Hidden,
                };
                Process.Start(startInfo);
                appID = Process.GetProcessesByName(appCheck)[0].Id;
                Console.WriteLine(appCheck + " Has been Starterd - Process ID: " + appID);
                Console.WriteLine("");
            }
            else
            {
                foreach (Process theprocess in processlist)
                    if (theprocess.ProcessName == appCheck)
                    {
                        appID = theprocess.Id;
                        Console.WriteLine(appCheck + " Has been found - Process ID: " + appID);
                        Console.WriteLine("");
                    }
            }
            return appID;
        }
    } 
}

代码集2

using System;
using System.Runtime.InteropServices;
using Word = Microsoft.Office.Interop.Word;


namespace ImageIT.AppPrint
{

    public class PrintToImage
    {

        public void PrintWordDocument(string fileToPrint, int wordID)
        {
            object objMissing = System.Reflection.Missing.Value;

            Console.WriteLine("We are Currently in PrintToImage");
            Console.WriteLine("The current Word INSTANCE ID is: "+ wordID);
            //Word.Application objWord = new Word.Application();


            Word.Application objWord = (Word.Application)Marshal.GetActiveObject("Word.Application") as Word.Application;
            //objWord = System.Runtime.InteropServices.Marshal.GetActiveObject("Word.Application") as Word.Application;


            Word.Document objDoc = new Word.Document();

            //object fileName = fileToPrint;
            //Console.WriteLine("File to Print:" + fileToPrint);

            //objDoc = objWord.Documents.Open(ref fileName,
            //    ref objMissing, ref objMissing, ref objMissing, ref objMissing, ref objMissing,
            //    ref objMissing, ref objMissing, ref objMissing, ref objMissing, ref objMissing,
            //    ref objMissing, ref objMissing, ref objMissing, ref objMissing, ref objMissing);

            //object copies = "1";
            //object pages = "";
            //object range = Microsoft.Office.Interop.Word.WdPrintOutRange.wdPrintAllDocument;
            //object items = Microsoft.Office.Interop.Word.WdPrintOutItem.wdPrintDocumentContent;
            //object pageType = Microsoft.Office.Interop.Word.WdPrintOutPages.wdPrintAllPages;
            //object objTrue = true;
            //object objFalse = false;

            //objDoc.PrintOut(
            //    ref objTrue, ref objFalse, ref range, ref objMissing, ref objMissing, ref objMissing,
            //    ref items, ref copies, ref pages, ref pageType, ref objFalse, ref objTrue,
            //    ref objMissing, ref objFalse, ref objMissing, ref objMissing, ref objMissing, ref objMissing);

            //objDoc.Close(ref objFalse, ref objMissing, ref objMissing);
        }


    }
}

如果我使用

//Word.Application objWord = new Word.Application();

打开一个新的MS-Word实例，文档按预期打印到图像。可能会有数百个文件到图像，所以我试图避免这种情况。

我能找到的关于如何实现这一目标的最佳文章是

https://blogs.msdn.microsoft.com/eric_carter/2009/03/12/attaching-to-an-already-running-office-application-from-your-application-using-getactiveobject-or-bindtomoniker/

然而，当尝试

时

//objWord = System.Runtime.InteropServices.Marshal.GetActiveObject("Word.Application") as Word.Application;

我收到“在当前背景下不存在objWord的名称”

我将其更改为

Word.Application objWord = (Word.Application)Marshal.GetActiveObject("Word.Application") as Word.Application;

应用程序崩溃了。

注意：大部分行已被注释掉以进行测试。

非常感谢任何帮助，谢谢你的进步。

感谢您的帮助 - 我最初的尝试并没有太远，并且有一个视觉工作室错误已经使用最新的15.5.1更新进行了更正---行被修改为 - ＆gt;
Word.Application objWord = System.Runtime.InteropServices.Marshal.GetActiveObject("Word.Application") as Word.Application;

使用已有的Word
