【问题描述】：
在我用 C# 自动生成 word 文档后，我试图将现有的 docx 文件保存在桌面上。我正在使用窗口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，当我再次尝试保存相同的文件名时，它会给我这个错误消息：
当文件正被另一个进程使用时，您无法保存。尝试 用新名称保存文件。 (C:...\Desktop\TempWord.docx)
我在Microsoft website 中读到它，如果存在现有文件名，我可以使用 SaveAs，它会自动覆盖它。
我不太清楚为什么会出现这种消息，因为在运行该程序时我根本没有打开任何其他 Word 文档。
我不太确定如何解决这个问题。也许我做了一些我没有看到的非常愚蠢的事情:(
这是我的代码：

//ADDING A NEW DOCUMENT FROM A TEMPLATE
oWordDoc = oWord.Documents.Add(ref oTemplatePath, ref oMissing, ref oMissing, ref oMissing);
int iTotalFields = 0;
foreach (Word.Field myMergeField in oWordDoc.Fields)
{
iTotalFields++;
Word.Range rngFieldCode = myMergeField.Code;
String fieldText = rngFieldCode.Text;
// ONLY GETTING THE MAILMERGE FIELDS
if (fieldText.StartsWith(" MERGEFIELD"))
{
// THE TEXT COMES IN THE FORMAT OF
// MERGEFIELD MyFieldName \\* MERGEFORMAT
// THIS HAS TO BE EDITED TO GET ONLY THE FIELDNAME "MyFieldName"
Int32 endMerge = fieldText.IndexOf("\\");
Int32 fieldNameLength = fieldText.Length - endMerge;
String fieldName = fieldText.Substring(11, endMerge - 11);
// GIVES THE FIELDNAMES AS THE USER HAD ENTERED IN .dot FILE
fieldName = fieldName.Trim();
// **** FIELD REPLACEMENT IMPLEMENTATION GOES HERE ****//
// THE PROGRAMMER CAN HAVE HIS OWN IMPLEMENTATIONS HERE
if (fieldName == "Name")
{
myMergeField.Select();
//Check whether the control text is empty
if (txtName.Text == "")
{
oWord.Selection.TypeText(" ");
}
else
{
oWord.Selection.TypeText(txtName.Text);
}
}
if (fieldName == "Address")
{
myMergeField.Select();
//Check whether the control text is empty
if (txtAddress.Text == "")
{
oWord.Selection.TypeText(" ");
}
else
{
oWord.Selection.TypeText(txtAddress.Text);
}
}
if (fieldName == "Age")
{
myMergeField.Select();
// check whether the control text is empty
if (txtAge.Text == "")
{
oWord.Selection.TypeText(" ");
}
else
{
oWord.Selection.TypeText(txtAge.Text);
}
}
if (fieldName == "EAddress")
{
myMergeField.Select();
// check whether the control text is empty
if (txtEmail.Text == "")
{
oWord.Selection.TypeText(" ");
}
else
{
oWord.Selection.TypeText(txtEmail.Text);
}
}
if (fieldName == "Company")
{
myMergeField.Select();
// Check whether the control text is empty
if (txtCompany.Text == "")
{
oWord.Selection.TypeText(" ");
}
else
{
oWord.Selection.TypeText(txtCompany.Text);
}
}
if (fieldName == "TelNo")
{
myMergeField.Select();
// Check whether the control text is empty
if (txtTelephone.Text == "")

oWord.Selection.TypeText(" ");
}

oWord.Selection.TypeText(txtCompany.Text);
}
}
if (fieldName == "ODetails")
{
myMergeField.Select();
// Check whether the control text is empty
if (txtOther.Text == "")
{
oWord.Selection.TypeText(" ");
}
else
{
oWord.Selection.TypeText(txtOther.Text);
}
}
}
}
oWord.Visible = false;
//Marshal.ReleaseComObject(oWordDoc.Fields);
//Marshal.ReleaseComObject(oWordDoc);
//Marshal.;
// If you want your document to be saved as docx
Object savePath = @"C:\Documents and Settings\YYC\Desktop\TempWord.doc";
//oWordDoc.Save();
oWordDoc.SaveAs(ref savePath
//,
//ref oMissing,
//ref oMissing,
//ref oMissing,
//ref oMissing,
//ref oMissing,
//ref oMissing,
//ref oMissing,
//ref oMissing,
//ref oMissing,
//ref oMissing,
//ref oMissing,
//ref oMissing,
//ref oMissing,
//ref oMissing,
//ref oMissing
);
// Close the Word document, but leave the Word application open.
// doc has to be cast to type _Document so that it will find the
// correct Close method.
object doNotSaveChanges = Word.WdSaveOptions.wdDoNotSaveChanges;
((Word._Document)oWordDoc).Close(ref doNotSaveChanges, ref oMissing, ref oMissing);
oWordDoc = null;
// word has to be case to type _Application so that it will find
// the correct Quit method.
((Word._Application)oWord).Quit(ref doNotSaveChanges, ref oMissing, ref oMissing);
oWord = null;
GC.Collect();
}
}
}
我不太确定我在哪里做错了。
编辑：我把原始代码放进去。
【问题讨论】：
-
你试过只保存吗？
-
@500-InternalServerError 是的，但我需要将其保存为文件名。
-
错误消息是什么意思.. 同样，当您通过 Microsoft.Office.Interop 处理 ComObjects 时，您需要使用 Marshal.ReleaseComObject(oWord) 处理它们，例如
-
@DJKRAZE 这是错误消息：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:\...\Desktop\TempWord.docx)
-
这不是特定于 word 的，而且每次您在磁盘上写入任何文件时都非常普遍：“当文件正在被另一个进程使用时，您无法保存”。这仅仅意味着在必须将其“保存为”（即）复制它之前，以某种方式创建了一个处理程序来“处理”现有文件。这可能是因为您的“另存为”进程正在尝试以写入模式访问文件，即使它只是为了复制它。我想您需要确保您的文件在尝试将其“另存为”之前已从任何资源中释放出来。
