C#NPOI操作EXCEL时进行复制单元格或复制区域的相关操作
以下为进行研发EXCEL操作时进行的相关测试代码，记录如下。

var xlSheet = (Microsoft.Office.Interop.Excel.Worksheet)ThisWorkbook.Worksheets["sheet1"];
Microsoft.Office.Interop.Excel.Range range = xlSheet.get_Range("P1", Type.Missing);
Microsoft.Office.Interop.Excel.Range range1 = xlSheet.get_Range("C6", Type.Missing);
range.Copy(range1);
ThisWorkbook.Save();//.SaveAs(filePath, Type.Missing, Type.Missing,Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlNoChange,Type.Missing, Type.Missing, Type.Missing, Type.Missing);
ThisWorkbook.Close();
if (ThisWorkbook != null)
