using (var package = new ExcelPackage(xlTemplate))
{

var wkshtFormula = package.Workbook.Worksheets["Formulas"];
wkshtFormula.Cells[rowCname, colCname].Value = cName;
package.Save();
return package.GetAsByteArray();
}
}
public byte[]ExcelSheet(FileInfo xlTemplate,string cName,string calcMethod,string username,int cid)
{
object[]tempObj=订单(用户名,cid);
List tList=新列表();
List acctList=新列表();
列表扇区列表=新列表();
tList=tempObj[0]作为列表;
acctList=tempObj[1]作为列表;
sectorList=tempObj[2]作为列表;
#区域集列变量
int colAcctNum=1;
int colAcctDesc=2;
int colAcctTrdLvl=5;
int colCname=6;
int rowCname=15;
#端区
使用(var包=新的ExcelPackage(xlTemplate))
{
var工作表=包.工作簿.工作表[“数据”];
var wkshtFormula=package.Workbook.Worksheets[“公式”];
wkshtFormula.Cells[rowCname,colCname].Value=cName;
package.Save();
return package.GetAsByteArray();
}
}
您必须删除对.Save()
的调用,因为它会作为副作用关闭pck。有关更多信息,请参见此:

?您好@Ernie我添加了上面的其余代码,您是否看到任何错误?
