C#生成CHM文件 实现在线网页自动保存

  三、CHM文件转换为Word

  接下来,我们来延伸下,利用反编译的文件,将CHM转换成Word文件。思路是这样的:利用反编译,得到hhc文件(hhc文件中包含htm或html文件的文件名)和一大堆web页面(如果一开始编译进去的是一大堆的话,呵呵),创建一个word文件,将html文件插入到word中,下面以实例的方式来实现。

  为了方便代码管理,我创建了一个类库项目,命名为CHM2Word,里面主要实现将CHM文件反编译并将反编译的文件整合为Word。在CreateCHM项目中调用代码即可,另需要你的机器安装Office2003(对应,添加引用 ->COM->Microsoft Word 11.0 Object Library)或2007(对应,添加引用->COM->Microsoft Word 12.0 Object Library)。

/// <summary>
        
/// 添加到word中
        
/// </summary>
        
/// <param name="pathFileHHC"></param>
        
/// <param name="saveAs"></param>
        
public void AddToWord(string pathFileHHC, string saveAs)
        {
            
if (File.Exists(saveAs))
            {
                throw
new Exception("word文件已经存在!");
            }
            
Object Nothing = System.Reflection.Missing.Value;
            Microsoft.Office.Interop.Word.Application wApp
= (Microsoft.Office.Interop.Word.Application)this.Word();
            Document wDoc
= wApp.Documents.Add(ref  Nothing, ref  Nothing, ref  Nothing, ref  Nothing);

            
if (wApp == null)
            {
                throw
new Exception("转换失败");
            }

            try
            {
                
string dirfile = "";//目录位置
                dirfile
= Path.GetDirectoryName(pathFileHHC);//目录的绝对路径
                
string[] lines = File.ReadAllLines(pathFileHHC);//读取hhc所有的行,这是为了找出里面的htm或html文件

                
string quote = "" + (char)34;
                
long filenumber = 0;

                
//遍历每一行
                foreach (
string TextLine in lines)
                {
                    
string htmFile = null;

                    
if (TextLine.IndexOf(".html", 0) > 0 || TextLine.IndexOf(".htm", 0) > 0)//如果这一行里面有.htm或者html.的字符串
                    {

                        
#region 以下代码是获取htm或者html文件名

                        
int endQuote = 0;
                        
if (TextLine.IndexOf(".html", 0) > 0)
                        {
                            endQuote
= TextLine.IndexOf(quote, TextLine.IndexOf(".html", 0));
                        }
                        
else
                        {
                            endQuote
= TextLine.IndexOf(quote, TextLine.IndexOf(".htm", 0));
                        }
                        
int quoteLoop = 0;
                        quoteLoop
= endQuote - 1;
                        
while (TextLine.Substring(quoteLoop, 1) != quote)
                        {
                            quoteLoop
= quoteLoop - 1;
                        }
                        htmFile
= TextLine.Substring(quoteLoop + 1, endQuote - quoteLoop - 1);//获取html文件的名字

                        #endregion
                        
                        
                        htmFile
= dirfile + "\\" + htmFile;

                        bool b
= false;//是否存在html文件
                        try
                        {
                            b
= File.Exists(htmFile);
                        }
                        catch (Exception ex)
                        {
                        }
                        
if ((!b))
                        {
                            continue;
                        }
                        
//将文件插入到word中
                        wApp.Selection.InsertParagraphAfter();
                        filenumber
+= 1;
                        
if (ProcessFile != null)
                        {
                            ProcessFile(this,
new ProcessFileEventArgs(htmFile, filenumber));
                        }
                        
//InsertFile参数说明
                        
//文件名: 必选的 String. 要被插入的文件名和路径。如果没有指定路径,Word默认为当前文件夹
                        
//Range: 可选的 Object. 如果指定的文件时word, 参数为bookmark(书签). 如果文件为其他类型(如Excel工作表), 参数为指定的一个单元或区域,如 R1C1:R3C4
                        
//确定是否转换 可选 Object.如果值为 True,则 word 应用程序将在插入非“ Word 文档”格式的文档时提示对转换进行确认。.
                        
//链接:  可选 Object. 如果值为 True,则可用 INCLUDETEXT 域插入该文档。
                        
//附件: 可选 Object. 为 True 时将该文件作为附件插入电子邮件消息中。
                        wApp.Selection.InsertFile(htmFile, ref
Nothing, ref Nothing, ref Nothing, ref Nothing);
                        
if ((filenumber % 10 == 0))
                            wDoc.Save();
                    }
                }
                wDoc.Save();
//保存word
                wDoc.Close(ref
Nothing, ref Nothing, ref Nothing);//关闭
                wApp.Quit(ref
Nothing, ref Nothing, ref Nothing);//释放

            }
            catch (Exception ex)
            {
            }
            finally
//释放对象
            {
                
if ((wDoc != null))
                {
                    Marshal.ReleaseComObject(wDoc);
                    wDoc
= null;
                }

                Marshal.ReleaseComObject(wApp);
                wApp
= null;
            }
        }

                WordApp

            }
