不行的话试试这个
{
//创建一个word的实例
Word.Application newApp = new Word.Application()
// 指定源文件和目标文件
object Source="c:\\abc\\Source.doc"
object Target="c:\\abc\\Target.rtf"
object Unknown =Type.Missing
// 打开要转换的Word文件
newApp.Documents.Open(ref Source,ref Unknown,
ref Unknown,ref Unknown,ref Unknown,
ref Unknown,ref Unknown,ref Unknown,
ref Unknown,ref Unknown,ref Unknown,
ref Unknown )
// 指定文档的类型
object format = Word.WdSaveFormat.wdFormatRTF
//改变文档类型
newApp.ActiveDocument.SaveAs(ref Target,ref format,
ref Unknown,ref Unknown,ref Unknown,
ref Unknown,ref Unknown,ref Unknown,
ref Unknown,ref Unknown,ref Unknown)
//关闭word实例
newApp.Quit(ref Unknown,ref Unknown,ref Unknown)
}
}
}
或是这种方法
在richtohtml函数中增加下面的代码就行了:
Dim strLastFontsize As Long
If strLastFontsize <>rtbRichTextBox.SelFontSize Then
strLastFontsize = rtbRichTextBox.SelFontSize
strHTML$ = strHTML$ + "<font-size=""" &strLastFontsize &""">"
End If
将RTF格式转换成普通的word格式方法如下：启动word软件，打开rtf格式的文档，按下键盘F12，d出另存为对话框，选择格式.doc或.docx格式，就实现了将rtf格式转换成普通的word格式。
日常生活中，我们总是在Word中进行文字的编辑，它不仅能够保存Text文本，还可以保存文本的格式等等。那么如果我要将一Word文档上的内容展示在网页上，该怎么做呢？这里我提供了一个小工具，你可以将Word转换为Html，需要显示的话，可以直接访问该Html，废话不多说，下面看代码。页面代码：
[html] view plaincopy
<span style="font-size:18px"><div>
<input id="File1" type="file" runat="server"/>
<asp:Button ID="btnConvert" runat="server" Text="转换" OnClick="btnConvert_Click" />
</div></span>
C#代码：
[csharp] view plaincopy
<span style="font-size:18px">using System
