使用C#将整个内容从一个Word文档复制到另一个Word文档

using Microsoft.Office.Interop.Word;

Application wordApp = new Application();
Document sourceDoc = wordApp.Documents.Open("源文档路径");
Document targetDoc = wordApp.Documents.Open("目标文档路径");

sourceDoc.Content.Copy();
targetDoc.Content.Paste();

targetDoc.Save();
targetDoc.Close();
wordApp.Quit();

using Microsoft.Office.Interop.Word;

namespace WordDocumentCopy
{
    class Program
    {
        static void Main(string[] args)
        {
            Application wordApp = new Application();
            Document sourceDoc = wordApp.Documents.Open("源文档路径");
            Document targetDoc = wordApp.Documents.Open("目标文档路径");

            sourceDoc.Content.Copy();
            targetDoc.Content.Paste();

            targetDoc.Save();
            targetDoc.Close();
            wordApp.Quit();
        }
    }
}
