C# 将数据从一个excel文件传输到另一个excel文件
我有一个会计程序，可以生成报告并保存在excel文件中。但我不需要这份报告中的大部分专栏。所以我创建了一个程序来删除我不需要的列。在转换后的文件中，我使用3个空列来写笔记、数据等。我每周生成此报告，因此在生成新报告时，我需要转换他，并将我在旧报告中写入的3列转移到新报告中。报告的第一列是UserID，因此我需要传输为该ID编写的注释和数据。新报告中可能缺少旧报告中的某些ID。 我创建了一个Windows窗体应用程序，它应该可以做到这一点，但效果不好。转换新报表，但不传输旧报表中的数据。有什么想法吗？？这是我的代码：C# 将数据从一个excel文件传输到另一个excel文件,c#,excel,C#,Excel,我有一个会计程序，可以生成报告并保存在excel文件中。但我不需要这份报告中的大部分专栏。所以我创建了一个程序来删除我不需要的列。在转换后的文件中，我使用3个空列来写笔记、数据等。我每周生成此报告，因此在生成新报告时，我需要转换他，并将我在旧报告中写入的3列转移到新报告中。报告的第一列是UserID，因此我需要传输为该ID编写的注释和数据。新报告中可能缺少旧报告中的某些ID。 我创建了一个Windows窗体应用程序，它应该可以做到这一点，但效果不好。转换新报表，但不传输旧报表中的数据。有什么想法
