c# - 使用 Microsoft.Office.Interop.Excel 读取所有行和列

Question

我有 4 列 4 行的 Excel 工作表。当我使用 Microsoft.Office.Interop.Excel.WorkSheet 读取列和行 Count 时，行数和列数分别为 1048576 行和 16384 列。计数必须行为 4，列为 4。我错过了什么？

            ApplicationClass excelApp = null;
            Workbook myWorkBook = null;
            Worksheet mySheet = null;
            Range dataRange = null;
            excelApp = new ApplicationClass();
            myWorkBook = excelApp.Workbooks.Open(@"C:\Users\Dev2Admin\Desktop\Employees.xlsx");
            mySheet = (Worksheet)myWorkBook.Sheets["Sheet1"];


            for (int row = 1; row < mySheet.Rows.Count; row++) // Count is 1048576 instead of 4
            {
                for (int col = 1; col < mySheet.Columns.Count; col++) // Count is 16384 instead of 4
                {
                    dataRange = (Range)mySheet.Cells[row, col];
                    Console.Write(String.Format(dataRange.Value2.ToString() + " "));
                }
                Console.WriteLine();
            }

您省略了 UsedRange 属性，在您的工作表上正确使用的列或行计数如下所示:

  int totalColumns = mySheet.UsedRange.Columns.Count;
  int totalRows = mySheet.UsedRange.Rows.Count;
