二、C# 将Word文档转换为HTML

日常生活中,我们总是在Word中进行文字的编辑,它不仅能够保存Text文本,还可以保存文本的格式等等。那么如果我要将一Word文档上的内容展示在网页上,该怎么做呢?这里我提供了一个小工具,你可以将Word转换为Html,需要显示的话,可以直接访问该Html,废话不多说,下面看代码。

页面代码:


<span style="font-size:18px;"><div> 
<input id="File1" type="file" runat="server"/> 
<asp:Button ID="btnConvert" runat="server" Text="转换" OnClick="btnConvert_Click" /> 
</div></span> 

C#代码:


<span style="font-size:18px;" deep="5">using System; 
using System.Data; 
using System.Configuration; 
using System.Collections; 
using System.Collections.Generic; 
using System.Linq; 
using System.Web; 
using System.Web.Security; 
using System.Web.UI; 
using System.Web.UI.WebControls; 
using System.Web.UI.WebControls.WebParts; 
using System.Web.UI.HtmlControls; 
using System.IO; 

protected void Page_Load(object sender, EventArgs e) 
{ 

} 

/// <summary> 
/// 将word转换为Html 
/// </summary> 
/// <param name="sender"></param> 
/// <param name="e"></param> 
protected void btnConvert_Click(object sender, EventArgs e) 
{ 
try 
{ 

//上传 
//uploadWord(File1); 
//转换 
wordToHtml(File1); 
} 
catch (Exception ex) 
{ 
throw ex; 
} 
finally 
{ 
Response.Write("恭喜,转换成功!"); 
} 

} 

//上传文件并转换为html wordToHtml(wordFilePath) 
///<summary> 
///上传文件并转存为html 
///</summary> 
///<param name="wordFilePath">word文档在客户机的位置</param> 
///<returns>上传的html文件的地址</returns> 
public string wordToHtml(System.Web.UI.HtmlControls.HtmlInputFile wordFilePath) 
{ 
Microsoft.Office.Interop.Word.ApplicationClass word = new Microsoft.Office.Interop.Word.ApplicationClass(); 
Type wordType = word.GetType(); 
Microsoft.Office.Interop.Word.Documents docs = word.Documents; 

// 打开文件 
Type docsType = docs.GetType(); 

//应当先把文件上传至服务器然后再解析文件为html 
string filePath = uploadWord(wordFilePath); 

//判断是否上传文件成功 
if (filePath == "0") 
return "0"; 
//判断是否为word文件 
if (filePath == "1") 
return "1"; 

object fileName = filePath; 

Microsoft.Office.Interop.Word.Document doc = (Microsoft.Office.Interop.Word.Document)docsType.InvokeMember("Open", 
System.Reflection.BindingFlags.InvokeMethod, null, docs, new Object[] { fileName, true, true }); 

// 转换格式,另存为html 
Type docType = doc.GetType(); 

string filename = System.DateTime.Now.Year.ToString() + System.DateTime.Now.Month.ToString() + System.DateTime.Now.Day.ToString() + 
System.DateTime.Now.Hour.ToString() + System.DateTime.Now.Minute.ToString() + System.DateTime.Now.Second.ToString(); 

// 判断指定目录下是否存在文件夹,如果不存在,则创建 
if (!Directory.Exists(Server.MapPath("~html"))) 
{ 
// 创建up文件夹 
Directory.CreateDirectory(Server.MapPath("~html")); 
} 

//被转换的html文档保存的位置 
string ConfigPath = HttpContext.Current.Server.MapPath("html/" + filename + ".html"); 
object saveFileName = ConfigPath; 

/*下面是Microsoft Word 9 Object Library的写法,如果是10,可能写成: 
* docType.InvokeMember("SaveAs", System.Reflection.BindingFlags.InvokeMethod, 
* null, doc, new object[]{saveFileName, Word.WdSaveFormat.wdFormatFilteredHTML}); 
* 其它格式: 
* wdFormatHTML 
* wdFormatDocument 
* wdFormatDOSText 
* wdFormatDOSTextLineBreaks 
* wdFormatEncodedText 
* wdFormatRTF 
* wdFormatTemplate 
* wdFormatText 
* wdFormatTextLineBreaks 
* wdFormatUnicodeText 
*/ 
docType.InvokeMember("SaveAs", System.Reflection.BindingFlags.InvokeMethod, 
null, doc, new object[] { saveFileName, Microsoft.Office.Interop.Word.WdSaveFormat.wdFormatFilteredHTML }); 

//关闭文档 
docType.InvokeMember("Close", System.Reflection.BindingFlags.InvokeMethod, 
null, doc, new object[] { null, null, null }); 

// 退出 Word 
wordType.InvokeMember("Quit", System.Reflection.BindingFlags.InvokeMethod, null, word, null); 
//转到新生成的页面 
return ("/" + filename + ".html"); 

} 


public string uploadWord(System.Web.UI.HtmlControls.HtmlInputFile uploadFiles) 
{ 
if (uploadFiles.PostedFile != null) 
{ 
string fileName = uploadFiles.PostedFile.FileName; 

int extendNameIndex = fileName.LastIndexOf("."); 
string extendName = fileName.Substring(extendNameIndex); 
string newName = ""; 
try 
{ 
//验证是否为word格式 
if (extendName == ".doc" || extendName == ".docx") 
{ 

DateTime now = DateTime.Now; 
newName = now.DayOfYear.ToString() + uploadFiles.PostedFile.ContentLength.ToString(); 

// 判断指定目录下是否存在文件夹,如果不存在,则创建 
if (!Directory.Exists(Server.MapPath("~wordTmp"))) 
{ 
// 创建up文件夹 
Directory.CreateDirectory(Server.MapPath("~wordTmp")); 
} 

//上传路径 指当前上传页面的同一级的目录下面的wordTmp路径 
uploadFiles.PostedFile.SaveAs(System.Web.HttpContext.Current.Server.MapPath("wordTmp/" + newName + extendName)); 
} 
else 
{ 
return "1"; 
} 
} 
catch 
{ 
return "0"; 
} 
//return "http://www.easck.com/wordTmp/" + newName + extendName; 
return System.Web.HttpContext.Current.Server.MapPath("wordTmp/" + newName + extendName); 
} 
else 
{ 
return "0"; 
} 
}</span>
