记录Office Add-in开发经验

原创文章转载请注明出处:@协思, http://zeeman.cnblogs.com

得益于微软系强大的共通能力和Visual Studio的开发支持,做Office插件不是什么难事。一点经验记录如下:

1. 如果要同时开发Word和Outlook插件,那么可将复用的代码封闭到独立的Library中。

2. 在可安装.NET Framework 4的系统上,可以嵌入WPF组件。

3. 由于Office的安全模型,安装部署里需要可信任证书的签名。

4. 初始化代码可在ThisAddIn添加,如Startup、Shutdown、Application.NewMailEx...

 

代码集锦


1. 获取文件名:

app = Globals.ThisAddIn.Application;

Path.GetExtension(app.ActiveDocument.FullName)

 

2.检查文档是否保存:

app = Globals.ThisAddIn.Application;

if (!app.ActiveDocument.Saved)

{

    if (MessageBox.Show("This command publish the disk version of a file to the server. Do you want to save your changes to disk before proceeding?", "warning",

        MessageBoxButtons.YesNo, MessageBoxIcon.Warning) == DialogResult.Yes)

    {

        try

        {

            app.ActiveDocument.Save();

            MessageBox.Show("save succeeded", "information", MessageBoxButtons.OK, MessageBoxIcon.Information);

        }

        catch (Exception ex)

        {

            MessageBox.Show("saved failed." + ex.Message, "error", MessageBoxButtons.OK, MessageBoxIcon.Error);

            return;

        }

    }

}

 

3. 获取文档内容,并添加自己的信息

public byte[] GetDocumentContent(Word.Document wordDoc, string headerText, string footerText)

{

    //使用Mail.RTFBody获取文档内容会丢失部分格式,所以这里还是采用剪贴板方式。

    //复制文档内容到剪贴板

    wordDoc.Content.Copy();

    using (RichTextBox rtb = new RichTextBox())

    {

        //添加头部信息

        rtb.AppendText(headerText);

        rtb.SelectAll();

        rtb.SelectionFont = new Font("Courier New", 11);

        rtb.SelectionColor = Color.Green;

        //添加正文

        rtb.Select(rtb.TextLength, 0);

        rtb.Paste();

        Clipboard.Clear();

        //添加尾部信息

        rtb.SelectionFont = new Font("Courier New", 11);

        rtb.SelectionColor = Color.Green;

        rtb.AppendText(footerText);

        using (System.IO.MemoryStream stream = new MemoryStream())

        {

            rtb.SaveFile(stream, RichTextBoxStreamType.RichText);

            return stream.ToArray();

        }

    }

}

 

4. outlook邮件正文转换为word文档:

object selObject = currentExplorer.Selection[1];

MailItem mail = selObject as MailItem;

if (mail == null)

{

    MessageBox.Show("non-mail item not supported.", "Information", MessageBoxButtons.OK, MessageBoxIcon.Information);

    return;

}

Word.Document wordDoc = (Word.Document)mail.GetInspector.WordEditor;
