在保存现有的word文档时遇到困难

Question

我想在C＃中自动化word文档后，在桌面上保存现有的docx文件。我正在使用窗体来执行我的应用程序。当桌面上没有相同的文件名时，我可以保存文档。但是，当我尝试再次保存相同的文件名时，它会给我这个错误信息：

当文件被另一个进程使用时，您无法保存。尝试使用新名称保存文件 。 （C：\桌面\ TempWord.docx）

我在Microsoft website我能使用另存为，如果有一个现有的文件名读它，它会自动覆盖它。

我不太确定为什么会出现这样的信息，因为当这个程序运行时我没有打开任何其他的word文档。

我不太清楚如何解决这个问题。也许我做了一件很愚蠢的，我没有看到:(

我也不太清楚，我没有错

编辑：我把原来的代码。

我做了一个这样的方法，所以把这行代码摆脱它在按钮生成和复制下面的新方法，所以你的新代码应该看起来像这样

private void butGenerate_Click(object sender, EventArgs e) 
{ 
    SaveWordTemp2WordDoc();  
}

    //OBJECT OF MISSING "NULL VALUE" 
    object oMissing = System.Reflection.Missing.Value; 
    //OBJECTS OF FALSE AND TRUE 
    Object oTrue = true; 
    Object oFalse = false; 

    //CREATING OBJECTS OF WORD AND DOCUMENT 
    Word.Application oWord = new Word.Application(); 
    Word.Document oWordDoc = new Word.Document(); 

    //SETTING THE VISIBILITY TO TRUE
