如何在网页中预览Word文件 [英] How Do I Preview Word File In A Webpage

问题描述

我正在使用VS13和sql server.i想要预览word文件，当它在数据库中上传并从detabase.i下载时已经使用了一些代码但是有一些错误。

下面给出的代码和错误---我使用的技术参考来自 http://www.aspsnippets.com/Articles/Display-Word-document-on-web-page-in-ASP.Net.aspx [ ^ ]



SETP 1：添加了对Microsoft Word 11.0对象库的引用

第2步：

 使用 Microsoft.Office; 
 使用 Microsoft.Office.Interop.Word; 
 使用 System.IO; 

第3步：

< pre lang =cs> protected void 上传（ object sender，EventArgs e）
{
object missingType = Type.Missing;
object readOnly = true ;
object isVisible = false ;
object documentFormat = 8 ;
string randomName = DateTime.Now.Ticks.ToString（）;
object htmlFilePath = Server.MapPath（ 〜/ Temp /）+ randomName + 。htm;
string directoryPath = Server.MapPath（ 〜/ Temp /）+ randomName + _ files;

// 上传word文档并保存到Temp文件夹
FileUpload1.SaveAs（Server.MapPath（ 〜/ Temp /）+ Path.GetFileName（FileUpload1 .PostedFile.FileName））;
object fileName = FileUpload1.PostedFile.FileName;

// 在后台打开word文档
ApplicationClass applicationclass = new ApplicationClass（）;
applicationclass.Documents.Open（ ref fileName，
ref readOnly，
ref missingType， ref missingType， ref missingType，
ref missingType， ref missingType， ref missingType，
ref missingType， ref missingType， ref isVisible，
ref missingType， ref missingType ， ref missingType，
ref missingType， ref missingType）;
applicationclass.Visible = false ;
Document document = applicationclass.ActiveDocument;

// 将word文档另存为HTML文件
document .SaveAs（ ref htmlFilePath， ref documentFormat， ref missingType，
ref missingType， ref missingType， ref missingType，
ref missingType， ref missingType， ref missingType，
ref missingType， ref missingType， ref missingType，
ref missingType， ref missingType， ref missingType，
ref missingType）;

// 关闭word文档
document.Close（ ref missingType， ref missingType， ref missingType ）;

// 删除上传的Word文件
File.Delete （Server.MapPath（ 〜/ Temp /）+ Path.GetFileName（FileUpload1.PostedFile.FileName ））;

// 将Html文件读取为字节数组并在浏览器中显示
byte [] bytes;
使用（FileStream fs = new FileStream（htmlFilePath.ToString（），FileMode.Open， FileAccess.Read））
{
BinaryReader reader = new BinaryReader（fs）;
bytes = reader.ReadBytes（（ int ）fs.Length）;
fs.Close（）;
}
Response.BinaryWrite（bytes）;
Response.Flush（）;

// 删除Html文件
File.Delete（ htmlFilePath.ToString（））;
foreach （字符串文件 in Directory.GetFiles（directoryPath））
{
File.Delete（file）;
}
Directory.Delete（directoryPath）;
Response.End（）;
}

ERROR SHOWING ::

1.类型'Microsoft.Office.Interop.Word.ApplicationClass'没有定义构造函数

2.'Microsoft.Office.Interop。 Word.ApplicationClass'不包含'Documents'的定义，也没有扩展方法'Documents'接受类型为'Microsoft.Office.Interop.Word.ApplicationClass'的第一个参数（你是否缺少using指令或程序集）引用？）

3.'Microsoft.Office.Interop.Word.ApplicationClass'不包含'Documents'的定义，也没有扩展方法'Documents'接受类型'Microsoft.Office的第一个参数可以找到.Interop.Word.ApplicationClass'（您是否缺少using指令或程序集引用？）

5.Interop类型'Microsoft.Office.Interop.Word.ApplicationClass'无法嵌入。请改用适用的界面。

6.Interop类型'Microsoft.Office.Interop.Word.ApplicationClass'无法嵌入。请改用适用的界面。



请告诉我哪里错了????

解决方案

请阅读Microsoft解释为什么不建议在服务器端设置中使用Office互操作：

http://support.microsoft.com/default.aspx?scid=kb;EN-US;q257757#kb2 [ ^ ]，

http://support.microsoft.com/kb/257757/en-us [ ^ ]。



相反，你可以使用Microsoft Open XML SDK。请参阅本文中引用的过去的答案：如何从MS Visual中的添加参考添加microsoft excel 15.0对象库Studio 2010 [ ^ ] 。

ERROR SHOWING::
1.The type 'Microsoft.Office.Interop.Word.ApplicationClass' has no constructors defined
2.'Microsoft.Office.Interop.Word.ApplicationClass' does not contain a definition for 'Documents' and no extension method 'Documents' accepting a first argument of type 'Microsoft.Office.Interop.Word.ApplicationClass' could be found (are you missing a using directive or an assembly reference?)
3.'Microsoft.Office.Interop.Word.ApplicationClass' does not contain a definition for 'Documents' and no extension method 'Documents' accepting a first argument of type 'Microsoft.Office.Interop.Word.ApplicationClass' could be found (are you missing a using directive or an assembly reference?)
5.Interop type 'Microsoft.Office.Interop.Word.ApplicationClass' cannot be embedded. Use the applicable interface instead.
6.Interop type 'Microsoft.Office.Interop.Word.ApplicationClass' cannot be embedded. Use the applicable interface instead.

Please tell me whats wrong????

解决方案

Please read the Microsoft explanation why Office interop is not recommended in server-side settings:
http://support.microsoft.com/default.aspx?scid=kb;EN-US;q257757#kb2[^],
http://support.microsoft.com/kb/257757/en-us[^].

Instead, you can use Microsoft Open XML SDK. Please see my past answered referenced in this one: How to add microsoft excel 15.0 object library from Add Reference in MS Visual Studio 2010[^].
