C#读写Word⽂件（五）--替换
有些时候我们需要通过word模板来打印，需要将数据库查询出来的数据填充到word模板⽂档并批量打印，此时我们可以在word模板设置好书签，然后通过在程序⾥⾯通过书签定位填充数据，然后再⽣成新的⽂档并且打印。
string fileName = “test.docx”;
Dictionary<string, string> dic = new Dictionary<string, string>();
dic.Add("团号", "12321");
dic.Add("线路简称", “线路23”);
dic.Add("所属社", “南京旅游社”);
dic.Add("当前⽇期", DateTime.Now.ToString("yyyy年MM⽉dd⽇"));
ReplaceContentByRemarks(fileName, dic);
/// <summary>
/// 替换指定书签的内容
/// </summary>
/// <param name="wordApp">当前打开的MSWord.ApplicationClass对象</param>
/// <param name="doc">当前打开的word⽂档，类型为MSWord._Document</param>
/// <param name="bookMarkName">书签名</param>
/// <param name="newValue">新值</param>
/// <returns></returns>
public static bool ReplaceContentByRemarks(MSWord.ApplicationClass wordApp,MSWord._Document doc,object bookMarkName,string newValue) {
/*
* 如果需要删除某个书签内容，只需要使⽤空格字符串替换就⾏(pty替换不⾏，可以使⽤" ")
*
*/
try
{
if (doc.Bookmarks.Exists(bookMarkName.ToString()))//如果书签存在
param name
{
doc.Bookmarks[bookMarkName].Range.Select();//选中书签⽂本
doc.ActiveWindow.Selection.TypeText(newValue);
return true;
}
}
return false;
}
catch (Exception e)
{
throw e;
}
}
/// <summary>

public static void ReplaceContentByRemarks(object docObject, Dictionary<string, string> dic)        {
MSWord.ApplicationClass wordApp = new MSWord.ApplicationClass();
wordApp.Visible = false;
object Nothing = System.Reflection.Missing.Value;
