要使用C#操作word，首先要添加引用：
1、添加引用->COM->Microsoft Word 11.0 Object Library
2、在.cs文件中添加
using Word;
下面的例子中包括C#对Word文档的创建、插入表格、设置样式等操作：
（例子中代码有些涉及数据信息部分被省略，重要是介绍一些C#操作word文档的方法）
public string CreateWordFile(string CheckedInfo)
…{
string message = “”;
try
…{
Object Nothing = System.Reflection.Missing.Value;
Directory.CreateDirectory(“C:/CNSI”); //创建文件所在目录
string name = “CNSI_” + DateTime.Now.ToShortString()+”.doc”;
object filename = “C://CNSI//” + name; //文件保存路径
//创建Word文档
Word.Application WordApp = new Word.ApplicationClass();
Word.Document WordDoc = WordApp.Documents.Add(ref Nothing, ref Nothing, ref Nothing, ref Nothing);
//添加页眉
WordApp.ActiveWindow.View.Type = WdViewType.wdOutlineView;
WordApp.ActiveWindow.View.SeekView = WdSeekView.wdSeekPrimaryHeader;
WordApp.ActiveWindow.ActivePane.Selection.InsertAfter(“[页眉内容]”);
WordApp.Selection.ParagraphFormat.Alignment = Word.WdParagraphAlignment.wdAlignParagraphRight;//设置右对齐
WordApp.ActiveWindow.View.SeekView = WdSeekView.wdSeekMainDocument;//跳出页眉设置
WordApp.Selection.ParagraphFormat.LineSpacing = 15f;//设置文档的行间距
//移动焦点并换行
object count = 14;
object WdLine = Word.WdUnits.wdLine;//换一行;
WordApp.Selection.MoveDown(ref WdLine, ref count, ref Nothing);//移动焦点
WordApp.Selection.TypeParagraph();//插入段落
//文档中创建表格
Word.Table newTable = WordDoc.Tables.Add(WordApp.Selection.Range, 12, 3, ref Nothing, ref Nothing);
//设置表格样式
newTable.Borders.OutsideLineStyle = Word.WdLineStyle.wdLineStyleThickThinLargeGap;
newTable.Borders.InsideLineStyle = Word.WdLineStyle.wdLineStyleSingle;
newTable.Columns[1].Width = 100f;
newTable.Columns[2].Width = 220f;
newTable.Columns[3].Width = 105f;
//填充表格内容
newTable.Cell(1, 1).Range.Text = “产品详细信息表”;
newTable.Cell(1, 1).Range.Bold = 2;//设置单元格中字体为粗体
//合并单元格
newTable.Cell(1, 1).Merge(newTable.Cell(1, 3));
WordApp.Selection.Cells.VerticalAlignment = Word.WdCellVerticalAlignment.wdCellAlignVerticalCenter;//垂直居中
WordApp.Selection.ParagraphFormat.Alignment = Word.WdParagraphAlignment.wdAlignParagraphCenter;//水平居中
//填充表格内容
newTable.Cell(2, 1).Range.Text = “产品基本信息”;
newTable.Cell(2, 1).Range.Font.Color = Word.WdColor.wdColorDarkBlue;//设置单元格内字体颜色
//合并单元格
newTable.Cell(2, 1).Merge(newTable.Cell(2, 3));
WordApp.Selection.Cells.VerticalAlignment = Word.WdCellVerticalAlignment.wdCellAlignVerticalCenter;
//填充表格内容
newTable.Cell(3, 1).Range.Text = “品牌名称：”;
newTable.Cell(3, 2).Range.Text = BrandName;
//纵向合并单元格
newTable.Cell(3, 3).Select();//选中一行
object moveUnit = Word.WdUnits.wdLine;
object moveCount = 5;
object moveExtend = Word.WdMovementType.wdExtend;
WordApp.Selection.MoveDown(ref moveUnit, ref moveCount, ref moveExtend);
WordApp.Selection.Cells.Merge();
//插入图片
string FileName = Picture;//图片所在路径
object LinkToFile = false;
object SaveWithDocument = true;
object Anchor = WordDoc.Application.Selection.Range;
WordDoc.Application.ActiveDocument.InlineShapes.AddPicture(FileName, ref LinkToFile, ref SaveWithDocument, ref Anchor);
WordDoc.Application.ActiveDocument.InlineShapes[1].Width = 100f;//图片宽度
WordDoc.Application.ActiveDocument.InlineShapes[1].Height = 100f;//图片高度
//将图片设置为四周环绕型
Word.Shape s = WordDoc.Application.ActiveDocument.InlineShapes[1].ConvertToShape();
s.WrapFormat.Type = Word.WdWrapType.wdWrapSquare;
newTable.Cell(12, 1).Range.Text = “产品特殊属性”;
newTable.Cell(12, 1).Merge(newTable.Cell(12, 3));
//在表格中增加行
WordDoc.Content.Tables[1].Rows.Add(ref Nothing);
WordDoc.Paragraphs.Last.Range.Text = “文档创建时间：” + DateTime.Now.ToString();//“落款”
WordDoc.Paragraphs.Last.Alignment = Word.WdParagraphAlignment.wdAlignParagraphRight;
//文件保存
WordDoc.SaveAs(ref filename, ref Nothing, ref Nothing, ref Nothing, ref Nothing, ref Nothing, ref Nothing, ref Nothing, ref Nothing, ref Nothing, ref Nothing, ref Nothing, ref Nothing,ref Nothing, ref Nothing, ref Nothing);
WordDoc.Close(ref Nothing, ref Nothing, ref Nothing);
WordApp.Quit(ref Nothing, ref Nothing, ref Nothing);
message=name+”文档生成成功，以保存到C:CNSI下”;
}
catch
…{
message = “文件导出异常！”;
}
return message;
}
=====================
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
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
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
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，……）
//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);
