Question

我有2张Excel表格。我的要求是，我必须将所有数据从一张Excel表格复制到另一张表格。下面是相同的代码片段，下面的代码是在Excel中将所有数据从一个工作表复制粘贴到另一个工作表，但它没有粘贴A1范围内的数据。

我希望将选定的数据粘贴到从第1行开始的另一个Excel工作表中。此外，我想在每次单击按钮时删除并插入新数据，而不是附加到同一按钮。请帮忙。

但它没有粘贴A1范围内的数据，因为第一行被认为是表格（表格）的标题要么手动创建它们，要么使用getRange来执行此操作。

// Create an array for the headers and add it to cells A1:C1.
object[] objHeaders = {"Order ID", "Amount", "Tax"};
m_objRange = m_objSheet.get_Range("A1", "C1");
m_objRange.Value = objHeaders;

为了在插入之前每次执行删除命令时插入新数据 oleDb不会删除删除命令

Excel.Range ran = (Excel.Range)sheet.Rows[5, Type.Missing];
ran.Select();
ran.Delete(Excel.XlDirection.xlUp);
