如何在asp.net 4.0，C＃Web应用程序中在线查看MS office文件

目前我正在开发一个用c＃和& amp; asp.net

用户可以存储批量文件。现在我想查看在浏览器中打开的所有可查看格式的文件（即图像，ms office，pdf等）（无需在客户端本地计算机中下载）。我已经完成了一半的工作，即我的应用程序适用于所有图像文件和pdf文件。但我面临ms office文件（即xls，xlsx，doc，docx，ppt等）格式的问题。我尝试了一些代码

Currently I am working on a file management system which developed in c# & asp.net
Where user can store bulk files. Now I want to view all viewable formats of file (i.e. image, ms office, pdf etc) open in browser (without downloading in clients local machine). I already done half of my job i.e. my application working fine for all image files and pdf files. But I facing problem with ms office files (i.e. xls, xlsx, doc, docx, ppt etc) formats. I tried some piece of code

protected void Page_Load(object sender, EventArgs e)
        {
            //Set the appropriate ContentType.
            string FilePath = MapPath("Test/xyz.pdf");
            Response.Buffer = true;
            Response.Clear();
            Response.ClearContent();
            Response.ClearHeaders();
            Response.ContentType = "Application/pdf";
            Response.AddHeader("content-disposition", "inline; filename=\"" + "xyz.pdf" + "\"");
            Response.Write(FilePath);
            Response.End();
        }

此代码仅适用于.pdf文件，但当我更改内容类型为Response.ContentType for word或excel文件Application / msword（对于Microsoft Word文件）Application / x-msexcel（对于Microsoft Excel文件）然后此代码不起作用。请指导我该怎么办。我应该使用任何工具，如谷歌文档查看器或其他东西。如果只有工具，那么请建议我一个很好的工具。



提前谢谢

This code works fine only for .pdf files but when I changed my content type Response.ContentType for word or excel files Application/msword (for Microsoft Word files) Application/x-msexcel (for Microsoft Excel files) then this code not works. Please guide me what can I do. Should I use any tool like google documents viewer or some thing else.If it is possible only with tool then please suggest me a good tool for this.

Thanks in advance
