Question

我所有的代码都有效，但是当我写入新工作表中的单元格时，将写入第一个工作表Sheet1。在单击事件结束之前，不会创建工作表。

在单击事件之后，我是否还会触发另一个事件来填充创建的新工作表？

我该如何解决？谢谢...

            xlWorkSheet.Select();
            range = excelSheet.Cells[1, 1];
            range.Value2 = "Test";

            xlWorkSheet = (Worksheet)xlWorkBook.Worksheets["Dashboard2"];
            xlWorkSheet.Select();
            range = excelSheet.Cells[1, 1];
            range.Value2 = "Test";
        }
    }
}

您要基于excelSheet定义范围，该范围在创建新工作表之前已定义为活动工作表。仅仅因为您选择了xlWorkSheet并不意味着excelSheet更改了值。您的代码应为

xlWorkSheet = (Worksheet)xlWorkBook.Worksheets["Dashboard"];
range = xlWorkSheet.Cells[1, 1];
range.Value2 = "Test";

xlWorkSheet = (Worksheet)xlWorkBook.Worksheets["Dashboard2"];
range = xlWorkSheet.Cells[1, 1];
range.Value2 = "Test";
