Microsoft.Office.Interop.Word.Application处置 [英] Disposing of Microsoft.Office.Interop.Word.Application

问题描述

（有点从职位的遵循（这仍然没有答案）：如何关闭/在Micorsoft.Office.Interop处理应用.Word在asp.net ）

(Somewhat of a follow on from the post (which remains unanswered): How to Close/ dispose Application in Micorsoft.Office.Interop.Word in asp.net)

使用以下code

Application app = new Application();
_Document doc = app.Documents.Open("myDocPath.docx", false, false, false);
doc.PrintOut(false);
doc.Close();

我试图以编程方式打开和打印文件。

I am attempting to open and print a file programmatically.

问题是每次我运行上面的code一个新的Winword.exe进程时启动，显然这很快吞噬了所有的记忆。

The problem is each time I run the above code a new WINWORD.exe process is started and obviously this quickly eats up all the memory.

应用程序类似乎并没有包含物/关闭或类似的方法。

The application class doesn't seem to contain a dispose/close or similar method.

在一些研究I（实现），并改变了code以下内容。

After a bit of research I (realized) and changed the code to the following.

 Application app = new Application();
 _Document doc = app.Documents.Open(fullFilePath + ".doc", false, false, false);
 doc.PrintOut(false);
 doc.Close();
 int res = System.Runtime.InteropServices.Marshal.ReleaseComObject(doc);
 int res1 = System.Runtime.InteropServices.Marshal.ReleaseComObject(app);

和我可以看到剩余的引用计数为零，但仍然过程？

And I can see the remaining reference count is zero but the processes remain?

PS：我使用的Microsoft.Office.Interop库的版本14

PS: I'm using Version 14 of the Microsoft.Office.Interop library.

推荐答案

也许尝试设置 DOC = NULL 并调用 GC.Collect的（）

编辑，不是我自己的code我忘了，我懂了，但是这是我用处置Excel和它的工作也许你可以收集来自这样的：

Edit, not really my own code I forget where I got it but this is what I use to dispose of Excel, and it does the job maybe you can glean something from this:

public void DisposeExcelInstance()
{
    app.DisplayAlerts = false;
    workBook.Close(null, null, null);
    app.Workbooks.Close();
    app.Quit();
    if (workSheet != null)
        System.Runtime.InteropServices.Marshal.ReleaseComObject(workSheet);
    if (workBook != null)
        System.Runtime.InteropServices.Marshal.ReleaseComObject(workBook);
    if (app != null)
        System.Runtime.InteropServices.Marshal.ReleaseComObject(app);
    workSheet = null;
    workBook = null;
    app = null;
    GC.Collect(); // force final cleanup!
}
