Question

我正在寻找一种方法来检索在Excel工作表中创建的某种表对象，然后对其进行操作。

我试过这样的事情：

Excel.Worksheet activeWorksheet = (Excel.Worksheet)Globals.ThisAddIn.Application.ActiveSheet;

        foreach (var sheetObject in activeWorksheet.ListObjects)
        {
            if ((sheetObject as Excel.TableObject) != null)
            {
                var table = (Excel.TableObject)sheetObject;
            }

            if ((sheetObject as Excel.DataTable) != null)
            {
                var table = (Excel.DataTable)sheetObject;
            }

            if ((sheetObject as Excel.PivotTable) != null)
            {
                var table = (Excel.PivotTable)sheetObject;
            }

            if ((sheetObject as Excel.ModelTable) != null)
            {
                var table = (Excel.ModelTable)sheetObject;
            }

            if ((sheetObject as Excel.QueryTables) != null)
            {
                var table = (Excel.QueryTables)sheetObject;
            }
        }

不幸的是，这个演员阵容中的任何一个都返回null然后返回null。你知道在C＃中检索这样的表可能有其他方法吗？

Answer 1

可能是Range？

来自：http://www.dotnetperls.com/excel

Range excelRange = sheet.UsedRange;
object[,] valueArray = (object[,])excelRange.get_Value(
    XlRangeValueDataType.xlRangeValueDefault);

要仅对工作表中创建的表格进行处理，我使用了以前答案中建议的“范围”：

        Excel.Worksheet activeWorksheet = (Excel.Worksheet)Globals.ThisAddIn.Application.ActiveSheet;

        foreach (Excel.ListObject table in activeWorksheet.ListObjects)
        {
            Excel.Range tableRange = table.Range;
            String[] dataInRows = new string[tableRange.Rows.Count];

            int i = 0;

            foreach (Excel.Range row in tableRange.Rows)
            {

                for (int j = 0; j < row.Columns.Count; j++)
                {
                    if (row.Cells[1, j + 1].Value2 != null)
                    {
                        dataInRows[i] = dataInRows[i] + "_" + row.Cells[1, j + 1].Value2.ToString();
                    }
                }

                i++;
            }
        }

C＃有没有办法在excel工作表中获取表对象
