1.与office无关使用 Aspose.Cells.dll，Aspose.Words.dll

2.使用Microsoft.Office.Interop.Excel Microsoft.Office.Interop.Word

3.打开文件

WORD：

object oMissing = Missing.Value;

_Application app = new Application();

_Document currentDoc = null;

app.Visible = false;

currentDoc = app.Documents.Open(filePath, ref oMissing, ref oMissing, ref oMissing);

//currentDoc = app.Documents.Add(templatesDirectory,ref oMissing, ref oMissing, ref oMissing); //打开模版

EXCEL：

var app = new Application();

 app.Visible = false;

var workbooks = app.Workbooks;

var workbook = workbooks.Open(filePath);

//var workbook = workbooks.Add(templatePath); //打开模版

var sheets = workbook.Sheets;

var sheet = (_Worksheet)sheets.get_Item(1);

4.保存或另存文件

Excel：

app.DisplayAlerts = false;

            app.ActiveWorkbook.SaveAs(filePath,

                        XlFileFormat.xlWorkbookNormal,

                        Missing.Value, Missing.Value, Missing.Value, Missing.Value,

                        XlSaveAsAccessMode.xlExclusive,

                        Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value);

WORD：

            object oMissing = Missing.Value;

            object oFileName = fileName;

            object oFormat = WdSaveFormat.wdFormatDocument;

            object oAddToRecentFiles = false;

            currentDoc.SaveAs(

                    ref oFileName, ref oFormat, ref oMissing, ref oMissing, ref oAddToRecentFiles,

                    ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing,

                    ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing);

5.退出文件：

WORD：

                object oSave = false;

                currentDoc.Close(ref oSave, ref oMissing, ref oMissing);

                Object nothing = Missing.Value;

                app.Quit(ref nothing, ref nothing, ref nothing); 

Excel：

        [DllImport("User32.dll", CharSet = CharSet.Auto)]

        public static extern int GetWindowThreadProcessId(IntPtr hwnd, out int ID);

 

            IntPtr t = new IntPtr(app.Hwnd);

            int k = 0;

            GetWindowThreadProcessId(t, out k);

            Process p = Process.GetProcessById(k);

            p.Kill();

 6.word 复制表格，插入分页符并黏贴

currentDoc.Tables[1].Select();

                app.Selection.Copy();

object mymissing = Missing.Value;                    

object myunit = WdUnits.wdStory;                    

app.Selection.EndKey(ref myunit, ref mymissing);                    

object pBreak = (int)WdBreakType.wdPageBreak;                    

app.Selection.InsertBreak(ref pBreak);

 

                    app.Selection.Paste();
