1、需下載 DocumentFormat.OpenXml.dll , 自行 google OpenXml 就會出現下載點。

2、編譯時會出現需參考 WindowsBase.dll , 請自行參考。

程式碼如下：
 

private void button1_Click(object sender, EventArgs e)
{
  string tPath = @"..\1.docx";
  string tOutPath = string.Format(@"..\{0}.docx", DateTime.Now.ToString("yyyyMMddHHmmss"));
  Dictionary <string, string> tReplaceDic = new Dictionary<string,string> ();
  tReplaceDic.Add("§§name§§", "王小明");
  tReplaceDic.Add("§§phone§§", "0912345678");
  tReplaceDic.Add("§§address§§", "台北市忠孝東路1號");
  tReplaceDic.Add("§§company§§", "google公司");

  bool tResult = WordReplace(tPath, tOutPath, tReplaceDic);

  if (tResult == true)
  {
    MessageBox.Show("OK");
  }
  else
  {
    MessageBox.Show("Not OK");
  }
}

小弟相信會有更好的寫法，此為筆記。
