代码示例

本文中的代码示例将说明如何完成以下任务:
  • 插入包含文本和格式的段落。
  • 浏览和修改文档中的不同范围。
  • 插入表格、设置表格格式并在表格中填充数据。
  • 添加图表。
要利用 Visual C# .NET 的自动化功能创建新的 Word 文档,请执行以下步骤:
  1. 启动 Microsoft Visual Studio .NET。在文件菜单上,单击新建,然后单击项目。在项目类型下,单击 Visual C# 项目,然后单击模板下的 Windows 应用程序。默认情况下会创建 Form1。
  2. 添加对 Microsoft Word 对象库的引用。为此,请按照下列步骤操作:
    1. 项目菜单上,单击添加引用
    2. COM 选项卡上,找到 Microsoft Word 对象库,然后单击选择
    3. 添加引用对话框中单击确定,接受您的选择。如果系统提示您为选定的库生成包装,请单击
  3. 视图菜单上,选择工具箱以显示工具箱,然后向 Form1 添加一个按钮。
  4. 双击 Button1。出现该窗体的代码窗口。
  5. 在代码窗口中,将以下代码
    private void button1_Click(object sender, System.EventArgs e){}					
    替换为:
    private void button1_Click(object sender, System.EventArgs e){	object oMissing = System.Reflection.Missing.Value;	object oEndOfDoc = "\\endofdoc"; /* \endofdoc is a predefined bookmark */ 	//Start Word and create a new document.	Word._Application oWord;	Word._Document oDoc;	oWord = new Word.Application();	oWord.Visible = true;	oDoc = oWord.Documents.Add(ref oMissing, ref oMissing,		ref oMissing, ref oMissing);	//Insert a paragraph at the beginning of the document.	Word.Paragraph oPara1;	oPara1 = oDoc.Content.Paragraphs.Add(ref oMissing);	oPara1.Range.Text = "Heading 1";	oPara1.Range.Font.Bold = 1;	oPara1.Format.SpaceAfter = 24;    //24 pt spacing after paragraph.	oPara1.Range.InsertParagraphAfter();	//Insert a paragraph at the end of the document.	Word.Paragraph oPara2;	object oRng = oDoc.Bookmarks.get_Item(ref oEndOfDoc).Range;	oPara2 = oDoc.Content.Paragraphs.Add(ref oRng);	oPara2.Range.Text = "Heading 2";	oPara2.Format.SpaceAfter = 6;	oPara2.Range.InsertParagraphAfter();	//Insert another paragraph.	Word.Paragraph oPara3;	oRng = oDoc.Bookmarks.get_Item(ref oEndOfDoc).Range;	oPara3 = oDoc.Content.Paragraphs.Add(ref oRng);	oPara3.Range.Text = "This is a sentence of normal text. Now here is a table:";	oPara3.Range.Font.Bold = 0;	oPara3.Format.SpaceAfter = 24;	oPara3.Range.InsertParagraphAfter();	//Insert a 3 x 5 table, fill it with data, and make the first row	//bold and italic.	Word.Table oTable;	Word.Range wrdRng = oDoc.Bookmarks.get_Item(ref oEndOfDoc).Range;	oTable = oDoc.Tables.Add(wrdRng, 3, 5, ref oMissing, ref oMissing);	oTable.Range.ParagraphFormat.SpaceAfter = 6;	int r, c;	string strText;	for(r = 1; r <= 3; r++)		for(c = 1; c <= 5; c++)		{			strText = "r" + r + "c" + c;			oTable.Cell(r, c).Range.Text = strText;		}	oTable.Rows[1].Range.Font.Bold = 1;	oTable.Rows[1].Range.Font.Italic = 1;	//Add some text after the table.	Word.Paragraph oPara4;	oRng = oDoc.Bookmarks.get_Item(ref oEndOfDoc).Range;	oPara4 = oDoc.Content.Paragraphs.Add(ref oRng);	oPara4.Range.InsertParagraphBefore();	oPara4.Range.Text = "And here's another table:";	oPara4.Format.SpaceAfter = 24;	oPara4.Range.InsertParagraphAfter();	//Insert a 5 x 2 table, fill it with data, and change the column widths.	wrdRng = oDoc.Bookmarks.get_Item(ref oEndOfDoc).Range;	oTable = oDoc.Tables.Add(wrdRng, 5, 2, ref oMissing, ref oMissing);	oTable.Range.ParagraphFormat.SpaceAfter = 6;	for(r = 1; r <= 5; r++)		for(c = 1; c <= 2; c++)		{			strText = "r" + r + "c" + c;			oTable.Cell(r, c).Range.Text = strText;		}	oTable.Columns[1].Width = oWord.InchesToPoints(2); //Change width of columns 1 & 2	oTable.Columns[2].Width = oWord.InchesToPoints(3);	//Keep inserting text. When you get to 7 inches from top of the	//document, insert a hard page break.	object oPos;	double dPos = oWord.InchesToPoints(7);	oDoc.Bookmarks.get_Item(ref oEndOfDoc).Range.InsertParagraphAfter();	do	{		wrdRng = oDoc.Bookmarks.get_Item(ref oEndOfDoc).Range;		wrdRng.ParagraphFormat.SpaceAfter = 6;		wrdRng.InsertAfter("A line of text");		wrdRng.InsertParagraphAfter();		oPos = wrdRng.get_Information                       (Word.WdInformation.wdVerticalPositionRelativeToPage);	}	while(dPos >= Convert.ToDouble(oPos));	object oCollapseEnd = Word.WdCollapseDirection.wdCollapseEnd;	object oPageBreak = Word.WdBreakType.wdPageBreak;	wrdRng.Collapse(ref oCollapseEnd);	wrdRng.InsertBreak(ref oPageBreak);	wrdRng.Collapse(ref oCollapseEnd);	wrdRng.InsertAfter("We're now on page 2. Here's my chart:");	wrdRng.InsertParagraphAfter();	//Insert a chart.	Word.InlineShape oShape;	object oClassType = "MSGraph.Chart.8";	wrdRng = oDoc.Bookmarks.get_Item(ref oEndOfDoc).Range;	oShape = wrdRng.InlineShapes.AddOLEObject(ref oClassType, ref oMissing, 		ref oMissing, ref oMissing, ref oMissing,		ref oMissing, ref oMissing, ref oMissing);	//Demonstrate use of late bound oChart and oChartApp objects to	//manipulate the chart object with MSGraph.	object oChart;	object oChartApp;	oChart = oShape.OLEFormat.Object;	oChartApp = oChart.GetType().InvokeMember("Application",		BindingFlags.GetProperty, null, oChart, null);	//Change the chart type to Line.	object[] Parameters = new Object[1];	Parameters[0] = 4; //xlLine = 4	oChart.GetType().InvokeMember("ChartType", BindingFlags.SetProperty,		null, oChart, Parameters);	//Update the chart image and quit MSGraph.	oChartApp.GetType().InvokeMember("Update",		BindingFlags.InvokeMethod, null, oChartApp, null);	oChartApp.GetType().InvokeMember("Quit",		BindingFlags.InvokeMethod, null, oChartApp, null);	//... If desired, you can proceed from here using the Microsoft Graph 	//Object model on the oChart and oChartApp objects to make additional	//changes to the chart.	//Set the width of the chart.	oShape.Width = oWord.InchesToPoints(6.25f);	oShape.Height = oWord.InchesToPoints(3.57f);	//Add text after the chart.	wrdRng = oDoc.Bookmarks.get_Item(ref oEndOfDoc).Range;	wrdRng.InsertParagraphAfter();	wrdRng.InsertAfter("THE END.");	//Close this form.	this.Close();}					
  6. 滚动到代码窗口的顶部。将下面的代码行添加到 using 指令列表的末尾:
    using Word = Microsoft.Office.Interop.Word;using System.Reflection;					
  7. 按 F5 键生成并运行程序。
  8. 单击 Button1,启动 Word 自动化功能并创建文档。
代码执行完成后,检查为您创建的文档。该文档包含两页设置了格式的段落、表格和图表。

使用模板

如果您要使用自动化功能创建的文档都是通用格式,则利用基于预设格式的模板的新文档来开始创建过程会更加容易。与从头创建文档相比,将某个模板与 Word 自动化客户端配合使用有两大优点:
  • 您可以对整个文档中的对象的格式设置和布局施加更多控制。
  • 可以使用较少的代码创建文档。
通过使用模板,可以精确地调整表格、段落和其他对象在文档中的布局,并可为这些对象添加格式设置。通过使用自动化功能,可以基于包含下面这样的代码的模板创建新文档:
object oTemplate = "c:\\MyTemplate.dot";oDoc = oWord.Documents.Add(ref oTemplate, ref oMissing,	ref oMissing, ref oMissing);				
在模板中,可以定义书签,这样,自动化客户端就可以在文档的特定位置加入可变文本,如下所示:
object oBookMark = "MyBookmark";oDoc.Bookmarks.Item(ref oBookMark).Range.Text = "Some Text Here";				
使用模板的另一个优点在于,您可以创建和存储希望在运行时应用的格式样式,如下所示:
object oStyleName = "MyStyle";oDoc.Bookmarks.Item(ref oBookMark).Range.set_Style(ref oStyleName);				
- 或者 -
object oStyleName = "MyStyle";oWord.Selection.set_Style(ref oStyleName);
