在ASP.NET里操作Word的第一步就是添加COM引用到你的工程里，通过右键点击“解决方案资源管理器”的“引用”，添加引用。选择COM选项卡，添加Microsoft Word 12.0 Object Library（其中12.0是Word版本号，根据当前电脑上安装的Word版本确定）。 ASP.Net会自动生成Word的COM包装类程序集添加到应用程序目录里。

using Word;

public string creatwordFile()
{
object Missing = Type.Missing;
//取得Word文件路径
string strTemp = "Doc/联盟推广协议.doc";
//新Word文件保存路径
string newFileName = "doc/"+name+".doc";
//创建一个名为WordApp的组件对象

string strBM;
object objBM;
Word.Application WordApp = new Word.ApplicationClass();
//必须设置为不可见
WordApp.Visible = false;
try
{
//创建以strTemp为模板的文档
object oTemplate = Server.MapPath(strTemp);
Word.Document WordDoc = WordApp.Documents.Add(ref oTemplate, ref Missing, ref Missing, ref Missing);
WordDoc.Activate();
