C#操縱Word

首先添加引用，方案總管－》引用－》添加－》Com－》瀏覽－》C:\Program Files\Microsoft Office\OFFICE11\MSWORD.OLB    我使用的是office 2003其他版本我不太清楚，.net會自動把OLB控制項轉換成DLL檔案使用方法:  object oMissing = System.Reflection.Missing.Value;   Word.Application oWord =new Word.Application();  oWord.Visible = false;//設定Word應用程式為不可見//建立一個Word文檔
   Word.Document oDoc=oWord.Documents.Add(ref oMissing,ref oMissing ,ref oMissing,ref oMissing);    //文檔內容的複製與粘貼    oDoc.Content.Copy();
    oDoc.Content.Paste()//文檔的另存新檔oDoc.SaveAs(ref fileName,ref saveFormat,ref oMissing,ref oMissing,ref oMissing,ref oMissing,ref oMissing,ref oMissing,ref oMissing,ref oMissing,ref oMissing,ref oMissing,ref oMissing,ref oMissing,ref oMissing,ref oMissing);//其他設定   oDoc.PageSetup.PaperSize=Word.WdPaperSize.wdPaperA3;//版面設定
   oDoc.PageSetup.Orientation=Word.WdOrientation.wdOrientLandscape;//橫板還是豎板
   oDoc.PageSetup.TextColumns.SetCount(2);//分欄//關閉Word   oWord.Application.Quit(ref b,ref oMissing,ref oMissing);
   System.Runtime.InteropServices.Marshal.ReleaseComObject(oWord);通過oDoc對象對Word文檔進行操作（word能做的它都能做）進行操作裡面有很多函數,有興趣的自己研究  另一方法：1：
對項目添加引用，Microsoft Word 11.0 Object Library
2：
在程式中添加 using Word = Microsoft.Office.Interop.Word;
3：
程式中添加
Word.Application app = new Microsoft.Office.Interop.Word.Application(); //可以開啟word程式
Word.Document doc = null;  //一會要記錄word開啟的文檔
word文檔和word程式可不是一回事奧！
4：
一般來說，對於抽取word內容，用的方法很少
public override void openFile(object fileName){} //開啟文檔
public override object readPar(int i){} //讀取word文檔的第i段
public override int getParCount(){} //返回word文檔一共幾段
public override void closeFile(){}  //關閉文檔
public override void quit(){}  //關閉word程式//從網頁上拷貝的目錄有時候會出現手動分行符號^l,，先將其換成斷行符號段落標記，才能正確讀取
public void replaceChar(){}5：代碼  public override void openFile(object fileName)

剛才是用讀取一段做的例子，如果要讀取一句或一篇只需要把doc.Paragraphs[i]（readPar中）改成doc.Sentences[i]或doc.content即可，因為都是微軟的東東，所以用起來沒有一點的障礙，再加上現在的vs2005做的很智能，所以先從java轉到了c#上7：
實際上，c#中讀取word是不用那麼麻煩的，但是如果考慮到可能還要抽取txt,ppt等多種格式，所以就寫了一個抽象類別，調用起來也方便，這就是為什麼我的程式方法開頭會有override的原因，總要考慮到通用，所以多了一些代碼。
