使用VSTO自动生成word文档

http://www.cnblogs.com/palo/archive/2009/06/02/vsto_vba.html

最近第一次用VSTO（Visual Studio Tools For Office），写了一个自动生成word报告的小程序，感觉VSTO非常难用。主要是对office对象模型不熟悉，不理解很多类、方法、属性的含义，word里面很简单的操作却不知道如何找到相应的类和方法去实现。在VS里面没办法直接看到VSTO的注释，查MSDN又很不方便。后来总算是找到了一个相对快捷的方法，其实VBA和VSTO使用的是一套对象模型，只要把需要实现的操作录制成宏，对照着VBA的代码就很容易写出相应的C#程序了。

下面举几个小例子。

输入标题：在当前光标处插入一段文字并设置成Heading 1样式，居中
在VBA中录制的宏如下：

Selection.TypeText Text:="Test Title"

Selection.Style = ActiveDocument.Styles("Heading 1")

Selection.ParagraphFormat.Alignment = wdAlignParagraphCenter

Selection.TypeParagraph

相应的C#代码：

//因为set_Style()要求传ref object参数，所以不能直接传string

object style_Heading1 = "Heading 1";

WordApp = new ApplicationClass();

WordApp.Selection.TypeText("Test Title");

//设置样式

WordApp.Selection.ParagraphFormat.set_Style(ref style_Heading1);

//居中

WordApp.Selection.ParagraphFormat.Alignment = WdParagraphAlignment.wdAlignParagraphCenter;

//换行

WordApp.Selection.TypeParagraph();

 

插入一个三行两列的表格，在第一行第一列填入今天的日期，设置样式，根据内容自动调整，去掉标题行
VBA：

ActiveDocument.Tables.Add Range:=Selection.Range, NumRows:=3, NumColumns:= _

2, DefaultTableBehavior:=wdWord9TableBehavior, AutoFitBehavior:= _

wdAutoFitFixed

With Selection.Tables(1)

If .Style <> "Table Grid" Then

.Style = "Table Grid"

End If

.ApplyStyleHeadingRows = True

.ApplyStyleLastRow = False

.ApplyStyleFirstColumn = True

.ApplyStyleLastColumn = False

.ApplyStyleRowBands = True

.ApplyStyleColumnBands = False

End With

Selection.Tables(1).Style = "Medium Shading 1 - Accent 5"

Selection.Tables(1).ApplyStyleHeadingRows = Not Selection.Tables(1). _

ApplyStyleHeadingRows

Selection.InsertDateTime DateTimeFormat:="M/d/yyyy", InsertAsField:=False, _

DateLanguage:=wdEnglishUS, CalendarType:=wdCalendarWestern, _

InsertAsFullWidth:=False

Selection.Tables(1).AutoFitBehavior (wdAutoFitContent)

C#：注意最后需要调用WordApp.Selection.EndKey把光标移到表格之后，否则在插入表格后光标还在表格之前

WordDoc = WordApp.Documents.Add(ref nothing, ref nothing, ref nothing, ref nothing);

//表格要使用的样式

object style_Table1 = "Medium Shading 1 - Accent 1";

object wdStory = WdUnits.wdStory;

//添加表格

Table table = WordDoc.Tables.Add(WordApp.Selection.Range, 3, 2, ref nothing, ref nothing);

//设置样式

table.set_Style(ref style_Table1);

//去掉标题行

table.ApplyStyleHeadingRows = false;

//在第一行第一列插入日期

//注意：word中表格的行列起始下标都是1

table.Cell(1, 1).Range.Text = DateTime.Today.ToShortDateString();

//根据内容自动调整

table.AutoFitBehavior(WdAutoFitBehavior.wdAutoFitContent);

//将光标移到表格后

WordApp.Selection.EndKey(ref wdStory, ref nothing);

 

在纵向页面中插入一个横向的页面
VBA：

Selection.InsertBreak Type:=wdSectionBreakNextPage

WordBasic.TogglePortrait Tab:=3, PaperSize:=0, TopMargin:="1.25", _

BottomMargin:="1.25", LeftMargin:="1", RightMargin:="1", Gutter:="0", _

PageWidth:="11", PageHeight:="8.5", Orientation:=1, FirstPage:=0, _

OtherPages:=0, VertAlign:=0, ApplyPropsTo:=0, FacingPages:=0, _

HeaderDistance:="0.5", FooterDistance:="0.5", SectionStart:=2, _

OddAndEvenPages:=0, DifferentFirstPage:=0, Endnotes:=0, LineNum:=0, _

StartingNum:=1, FromText:=wdAutoPosition, CountBy:=0, NumMode:=0, _

TwoOnOne:=0, GutterPosition:=0, LayoutMode:=0, CharsLine:=39, LinesPage:= _

36, CharPitch:=220, LinePitch:=360, DocFontName:="+Body Asian", _

DocFontSize:=11, PageColumns:=1, TextFlow:=0, FirstPageOnLeft:=0, _

SectionType:=1, FolioPrint:=0, ReverseFolio:=0, FolioPages:=1

Selection.InsertBreak Type:=wdSectionBreakNextPage

WordBasic.TogglePortrait Tab:=3, PaperSize:=0, TopMargin:="1", _

BottomMargin:="1", LeftMargin:="1.25", RightMargin:="1.25", Gutter:="0", _

PageWidth:="8.5", PageHeight:="11", Orientation:=0, FirstPage:=0, _

OtherPages:=0, VertAlign:=0, ApplyPropsTo:=0, FacingPages:=0, _

HeaderDistance:="0.5", FooterDistance:="0.5", SectionStart:=2, _

OddAndEvenPages:=0, DifferentFirstPage:=0, Endnotes:=0, LineNum:=0, _

StartingNum:=1, FromText:=wdAutoPosition, CountBy:=0, NumMode:=0, _

TwoOnOne:=0, GutterPosition:=0, LayoutMode:=0, CharsLine:=58, LinesPage:= _

24, CharPitch:=220, LinePitch:=360, DocFontName:="+Body Asian", _

DocFontSize:=11, PageColumns:=1, TextFlow:=0, FirstPageOnLeft:=0, _

SectionType:=1, FolioPrint:=0, ReverseFolio:=0, FolioPages:=1

 

去掉冗余代码，C#很简单：

object sectionBreak = WdBreakType.wdSectionBreakNextPage;

//插入分节符

WordApp.Selection.InsertBreak(ref sectionBreak);

//将当前页面调整为横向

WordApp.Selection.PageSetup.Orientation = WdOrientation.wdOrientLandscape;

//再插入分节符

WordApp.Selection.InsertBreak(ref sectionBreak);

//将当前页面调整为纵向

WordApp.Selection.PageSetup.Orientation = WdOrientation.wdOrientPortrait;

设置项目符号（默认）及自定义的编号（Hello 1， Hello 2，……）

VBA看着很复杂，实际上很多代码都浪费在只需使用默认值的参数上。C#就很简单：

//应用默认项目符号

WordApp.Selection.Range.ListFormat.ApplyBulletDefault(ref nothing);

WordApp.Selection.TypeText("A1");

WordApp.Selection.TypeParagraph();

WordApp.Selection.TypeText("A2");

WordApp.Selection.TypeParagraph();

WordApp.Selection.TypeText("A3");

WordApp.Selection.TypeParagraph();

//使用完记得取消掉

WordApp.Selection.Range.ListFormat.ApplyBulletDefault(ref nothing);

//应用编号

WordApp.Selection.Range.ListFormat.ApplyNumberDefault(ref nothing);

//自定义格式

WordApp.Selection.Range.ListFormat.ListTemplate.ListLevels[1].NumberFormat = "Hello %1:";

WordApp.Selection.TypeText("B1");

WordApp.Selection.TypeParagraph();

WordApp.Selection.TypeText("B2");

WordApp.Selection.TypeParagraph();

WordApp.Selection.TypeText("B3");

WordApp.Selection.TypeParagraph();

//取消编号

WordApp.Selection.Range.ListFormat.ApplyNumberDefault(ref nothing);
