我正在尝试使用C＃.net创建一个word文档，我所做的就是使用这个代码使用Interop.Word：
object oMissing = System.Reflection.Missing.Value;
object oEndOfDoc = "\\endofdoc"; /* \endofdoc is a predefined bookmark */
//Start Word and create a new document.
Word._Application oWord;
Word._Document oDoc;
oWord = new Word.Application();
oWord.Visible = true;
oDoc = oWord.Documents.Add(ref oMissing, ref oMissing,
ref oMissing, ref oMissing);
//Insert a paragraph at the beginning of the document.
Word.Paragraph oPara1;
oPara1 = oDoc.Content.Paragraphs.Add(ref oMissing);
oPara1.Range.Text = "Heading 1";
oPara1.Range.Font.Bold = 1;
oPara1.Format.SpaceAfter = 24; //24 pt spacing after paragraph.
oPara1.Range.InsertParagraphAfter();
//Insert a paragraph at the end of the document.
Word.Paragraph oPara2;
object oRng = oDoc.Bookmarks.get_Item(ref oEndOfDoc).Range;
oPara2 = oDoc.Content.Paragraphs.Add(ref oRng);
oPara2.Range.Text = "Heading 2";
oPara2.Format.SpaceAfter = 6;
oPara2.Range.InsertParagraphAfter();
一切正常，但我的文字是阿拉伯语并设置为oPara1.Range.Font.Bold = 1;不起作用也改变字体名称
你能否弄清楚为什么会遇到这种麻烦？我该如何解决？
