C#把Doc文檔轉換成HTML等其它格式

利用microsoft Word 9.0 Object Library可以在頁面中對Doc文檔進行格式轉換。有關Word對象的一些方法可以參考Open和Save。下面是進行轉換的代碼[C#]：

/// <summary>
/// WordToHtml 的摘要說明。
/// 首先要添加引用：Microsoft Word 9.0 Object Library
/// </summary>

word.applicationclass word = new Word.ApplicationClass();
Type wordType = word.GetType();
Word.Documents docs = word.Documents;

// 打開文件
Type docsType = docs.GetType();
object fileName = "d://tmp//aaa.doc";
Word.Document doc = (Word.Document)docsType.InvokeMember("Open",
System.Reflection.BindingFlags.InvokeMethod, null, docs, new Object[] {fileName, true, true});

// 轉換格式，另存為
Type docType = doc.GetType();
object saveFileName = "d://tmp//aaa.html";
//下面是Microsoft Word 9 Object Library的寫法，如果是10，可能寫成：
//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, Word.WdSaveFormat.wdFormatHTML});

// 退出 Word
wordType.InvokeMember("Quit", System.Reflection.BindingFlags.InvokeMethod, null, word, null);
