使用VSTO向Word文档中添加数学公式

这是个极其简单的实例，用来向Word文档中添加一个数学汇总公式。

[csharp]
using System; 
using System.Collections.Generic; 
using System.ComponentModel; 
using System.Data; 
using System.Drawing; 
using System.Linq; 
using System.Text; 
using System.Windows.Forms; 
using Word = Microsoft.Office.Interop.Word; 
using System.Diagnostics; 
 
namespace VSTOInsertEquations 
{ 
    public partial class Form1 : Form 
    { 
        public Form1() 
        { 
            InitializeComponent(); 
        } 
 
        private void button1_Click(object sender, EventArgs e) 
        { 
            Word.Application wdApplication = null; 
            Process[] pl = Process.GetProcessesByName("WINWORD.exe"); 
            if (pl.Length > 0) 
            { 
                wdApplication = (Word.Application)System.Runtime.InteropServices 
                    .Marshal.GetActiveObject("Word.Application"); 
            } 
            else 
            { 
                wdApplication = new Word.Application(); 
            } 
            if (wdApplication != null) 
            { 
                Word.Document newDocument = wdApplication.Documents.Add(); 
                //一下代码添加了汇总公式 
                Word.Range wdFunctionR = wdApplication.Selection.OMaths 
                    .Add(wdApplication.Selection.Range);
