Question

我正在使用 EPPlus库并编写此代码（仅用于测试）

    private void btnCargarExcel_Click(object sender, EventArgs e)
    {
        if (this.openFileDialog1.ShowDialog() == DialogResult.OK)
        {
            if (System.IO.File.Exists(openFileDialog1.FileName))
            {
                Stopwatch stopWatch = new Stopwatch();
                stopWatch.Start();
                Thread.Sleep(10000);

                filePath.Text = openFileDialog1.FileName.ToString();

                var existingFile = new FileInfo(openFileDialog1.FileName.ToString());

                using (var package = new ExcelPackage(existingFile))
                {
                    ExcelWorkbook workbook = package.Workbook;
                    if (workbook != null)
                    {
                        if (workbook.Worksheets.Count > 0)
                        {
                            ExcelWorksheet currentWorkSheet = workbook.Worksheets.First();
                            textBox3.Text = currentWorkSheet.Cells[0, 1].Value.ToString();
                        }                            
                    }
                }

                stopWatch.Stop();

                TimeSpan ts = stopWatch.Elapsed;
                executiontime.Text =
                    String.Format("{0:00}:{1:00}:{2:00}.{3:00}", ts.Hours, ts.Minutes, ts.Seconds,
                                  ts.Milliseconds / 10).ToString();
            }
            else
            {
                MessageBox.Show("No se pudo abrir el fichero!");
                System.Runtime.InteropServices.Marshal.ReleaseComObject(appExcel);
                appExcel = null;
                System.Windows.Forms.Application.Exit();
            }
        }
    }

测试我的代码是否正常工作我添加了这一行textBox3.Text = currentWorkSheet.Cells[0, 1].Value.ToString();（我从here得到了想法）但是当我执行应用程序时出现此错误：

超出范围

为什么？我错过了什么或者我做错了什么？这是错误的堆栈跟踪：

另外（并且不知道是否最好为此打开一个新问题）并且与此相同的主题相关，我如何获取每个工作表的名称（文本），然后构建选项按钮尽可能多的工作表在我的工作簿中？

Answer 1

Excel工作表中的第一个单元格是[1,1]。 currentWorkSheet.Cells [0,1]可能是此异常的原因，单元格[0,1]超出范围

使用EPPus从Excel文件读取值导致“行超出范围”错误
