ASP.NET替换WORD文档，字体发生了变化

[rocket204]

我是仿照这个例子做的
http://www.alixixi.com/weBuild/subject4/20051213147543.html

try
{
string str = doc.Content.Text;
doc.Content.Text = str.Replace("%DATE", DateTime.Now.ToString("yyyy年MM月dd日"));
foreach (Word.Comment bm in doc.Comments)　　
{
ClientScript.RegisterStartupScript(this.GetType(), "", "<script>alert('" + bm.Range.Text + "');</script>");
}
object fn = (object)Server.MapPath("test/temp.doc");
doc.SaveAs(ref fn, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing);
Response.Redirect("test/temp.doc");　//直接打开用ie打开另存的文件，然后可直接调用ie里的打印功能
}

但是替换后，字体发生了变化，我摸版中是楷体的，变成了宋体，请问怎么才能使字体不发生变化

没人知道答案吗？
