C# WINWORD.exe 不会退出 - 目录文件升序排序

Question

我不是 C# 专家，但我尽力了，这是一个小型控制台应用程序，应该获得 2 个 arg2（通过将 args 传递给 exe 或通过控制台输入）我有 2 个问题，我找不到任何其他解决方案

合并文件的顺序不正确，如果文件名有包括字母。前任。 (1.docx , 2.docx , 3.docx ) 有效 => result.docx(1,2,3) (1test.docx , 2rice.docx , 3john.docx ) => result.docx(3,1,2)
在其应用程序完成后无法让 WINWORD.exe 关闭完成

PS: This exe is being called by PHP line CMD.EXE

我尝试了所有可能的命令来释放 com 对象然后关闭应用程序，我的错误是什么？如何正确优化代码？

您不需要进行任何这些 COM 调用或显式 GC 调用，也不需要将内容显式设置为 null。您只需致电 Application.Quit.
