为 Microsoft Word 创建自动化客户端
- 启动 Visual Studio .NET。
- 在文件菜单上,单击新建,然后单击项目。从 Visual C# 项目类型中选择 Windows 应用程序。默认情况下会创建 Form1。
- 添加对 Microsoft Word 对象库的引用。为此,请按照下列步骤操作:
- 在项目菜单上,单击添加引用。
- 在 COM 选项卡上,找到 Microsoft Word 对象库,然后单击选择。
注意:Microsoft Office 2003 包含主 Interop 程序集 (PIA)。 Microsoft Office XP 不包含 PIA,但您可以下载 PIA。 有关 Office XP PIA 的其他信息,请单击下面的文章编号,以查看 Microsoft 知识库中相应的文章:
328912 INFO:Microsoft Office XP PIA 可供下载 - 在添加引用对话框中单击确定以接受您的选择。如果系统提示您为选定的库生成包装,请单击是。
- 在视图菜单上,选择工具箱以显示工具箱,然后向 Form1 添加一个按钮。
- 双击 Button1。出现该窗体的代码窗口。
- 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)
{
Word.Application oWord;
Word._Document oDoc;
object oMissing = Missing.Value;
object oDocBuiltInProps;
object oDocCustomProps; //Create an instance of Microsoft Word and make it visible.
oWord = new Word.Application();
oWord.Visible = true; //Create a new Document and get the BuiltInDocumentProperties collection.
oDoc = oWord.Documents.Add(ref oMissing, ref oMissing, ref oMissing,
ref oMissing);
oDocBuiltInProps = oDoc.BuiltInDocumentProperties;
Type typeDocBuiltInProps = oDocBuiltInProps.GetType(); //Get the Author property and display it.
string strIndex = "Author";
string strValue;
object oDocAuthorProp = typeDocBuiltInProps.InvokeMember("Item",
BindingFlags.Default |
BindingFlags.GetProperty,
null,oDocBuiltInProps,
new object[] {strIndex} );
Type typeDocAuthorProp = oDocAuthorProp.GetType();
strValue = typeDocAuthorProp.InvokeMember("Value",
BindingFlags.Default |
BindingFlags.GetProperty,
null,oDocAuthorProp,
new object[] {} ).ToString();
MessageBox.Show( "The Author is: " + strValue,"Author" ); //Set the Subject property.
strIndex = "Subject";
strValue = "The Subject";
typeDocAuthorProp.InvokeMember("Item",
BindingFlags.Default |
BindingFlags.SetProperty,
null,oDocBuiltInProps,
new object[] {strIndex,strValue} ); //Add a property/value pair to the CustomDocumentProperties collection.
oDocCustomProps = oDoc.CustomDocumentProperties;
Type typeDocCustomProps = oDocCustomProps.GetType(); strIndex = "Knowledge Base Article";
strValue = "Q303296";
object[] oArgs = {strIndex,false,
MsoDocProperties.msoPropertyTypeString,
strValue}; typeDocCustomProps.InvokeMember("Add",BindingFlags.Default |
BindingFlags.InvokeMethod, null,
oDocCustomProps, oArgs ); MessageBox.Show("Select \"Properties\" from the File menu "
+ "to view the changes.\nSelect the Summary tab to view "
+ "the Subject property and the Custom tab to view the Knowledge"
+ "Base Article property.", "Check File Properties",
MessageBoxButtons.OK,MessageBoxIcon.Information);
} - 滚动到代码窗口顶部,然后将以下行添加到 using 指令列表的末尾:
using Microsoft.Office.Core;
using Word = Microsoft.Office.Interop.Word;
using System.Reflection; - 按 F5 键运行该应用程序。
注意:DocumentProperties 和 DocumentProperty 接口是晚期绑定接口。若要使用这些接口,必须像对待 IDispatch 接口那样对待它们。
