最近業務需要批量打印准考證信息
1、根據Table數據進行循環替換，每次替換的時候只替換Word中第一個Table的數據，
2、每次替換之后將Word中第一個Table數據進行復制，將復制Table和上次替換的Table合並為一個Table。由於替換后的Table中不存在占位符，只有復制的Table中存在占位符，所有每次循環根據占位符替換最新數據就可以達到批量生成Word的目的了
Word模板：
批量替換后的Word：

調用：
//Word模板路徑 string word_ModelName = "SmallList - 副本.doc"; //生成后的Word文件路徑 string word_SaveName = DateTime.Now.ToString("yyyyMMddHHmmssfffffff")+".doc"; //重復替換字典數據 //根據字典的Key字段，找到表格中的對應列，然后根據字典的value字段，找到Word中對應要替換的字段 Dictionary<string, string> dict = new Dictionary<string, string>(); dict.Add("Name", "Name"); dict.Add("Age", "Age"); dict.Add("ShenFenNumber", "ShenFenNumber"); dict.Add("ZhunKaoNumber", "ZhunKaoNumber"); dict.Add("Gender", "Gender"); //不重復數據字典 //Key為Word中需要替換的占位符 Value為替換后的內容 Dictionary<string, string> dictNo = new Dictionary<string, string>(); dictNo.Add("ExamName", "《計算機導論》"); dictNo.Add("ExamTime", "120分鍾"); WordUtility createWord = new WordUtility(word_ModelName, word_SaveName); createWord.GenerateWord(GetDT(), dict, dictNo);
