//求大神指导为什么出不来结果~各位大牛快快显灵~ C#/文档生成 --------------------编程问答-------------------- 帮顶！！！！！另外，

求大神帮忙：http://bbs.csdn.net/topics/390501016 --------------------编程问答-------------------- object oTemplate;
        private void button1_Click(object sender, EventArgs e)
        {
            object oMissing = System.Reflection.Missing.Value;
            oWord = new Word.Application();
            oWord.Visible = false;
            object oTemplate = "D://test_moban2.dot";
不要重复声明，去掉下面那个声明看看oTemplate = "D://test_moban2.dot";

补充：.NET技术 ,  C#
