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();
}
}
}
为了测试我的代码是否工作正常，我添加了这一行textBox3.Text = currentWorkSheet.Cells[0, 1].Value.ToString();（我从这里得到了这个想法）但是当我执行应用程序时，我得到了这个错误：
行超出范围
这是为什么？我错过了什么或我做错了什么？这是错误的堆栈跟踪：

另外（不知道是否最好为此打开一个新问题）并与同一主题相关，我如何获取每个工作表的名称（文本），然后构建选项按钮，因为我的工作表中有很多工作簿？
