如何在后台运行模拟返回 (ENTER) 命中的程序

我编写了一个 C# 程序，将 1997 - 2003 .DOC Word 文档转换为文本文件。 我正在从命令行运行该程序。 我必须转换超过 300,000 个文档。 每个文档的处理时间从 0.7 秒到 1.5 秒不等。 该程序工作正常。 我正在使用库：

• Microsoft.Office.Interop.Word

这里的问题是很少有Word文档损坏，有些启用了宏，有些被锁定以进行编辑等。 我能够处理大多数错误，除了一个。

我可以在此链接上找到我遇到的类似问题(除了我正在转换为 TXT 的事实(： Microsoft 互操作保存为命令失败

这是我的问题;我每 25 - 35 分钟收到一次错误。 该库中的某些内容会捕获错误并生成一个弹出窗口，说"文件遇到错误。命令失败"，弹出窗口只有一个"确定"按钮。

当弹出警告消息窗口时，程序将暂停，直到有人手动点击"RETURN"，或单击"确定"按钮。

如何编写在后台运行并模拟某人按下 RETURN 按钮的程序？ 这样，在命令行中生成的弹出窗口将消失，我的程序将恢复。
