嘿,我在处理Excel.Worksheet.Cells数组时遇到了转置行为.

我的第一个单元格必须位于[行= 10,列= 3]
我的第二个单元格必须位于[行= 11,列= 17]

然后使用这两个单元格作为边界,我创建一个范围并将其合并.
从上面提到的值可以看出,该范围应该基本上是水平的.

因此,为了帮助我,我创建了一个简单的辅助函数来合并单元格：

    public static void MergeRange(Excel.Worksheet worksheet, int startRowIdx, 
        int startColIdx, int endRowIdx, int endColIdx, bool across = false)
    {   //Get range boundaries.
        Excel.Range cells = worksheet.Cells;

        //commented out, resolved code is directly below - N. Miller, 9-24-2013
        //Excel.Range topleftCell = cells[startColIdx][startRowIdx];
        //Excel.Range bottomrightCell = cells[endColIdx][endRowIdx];
        Excel.Range topleftCell = cells[startRowIdx, startColIdx];
        Excel.Range bottomrightCell = cells[endRowIdx, endColIdx];

        //Merge range.
        Debug.WriteLine(String.Format("({0}, {1}) to ({2}, {3}).", startRowIdx, startColIdx, endRowIdx, endColIdx)); 
        Excel.Range range = worksheet.get_Range(topleftCell, bottomrightCell);
        Excel.Interior interior = range.Interior;
        interior.ColorIndex = XLColor.PERIWINKLE; //JUST HIGHLIGHTS RANGE FOR NOW.
        //range.Merge(across);

        //Cleanup
        Marshal.ReleaseComObject(interior);
        Marshal.ReleaseComObject(range);
        Marshal.ReleaseComObject(bottomrightCell);
        Marshal.ReleaseComObject(topleftCell);
        Marshal.ReleaseComObject(cells);
    }

在上面的代码中,我通过交换列和行来选择所需的单元格.与我的预期相反,这导致了预期的行为,但是与MSDN文档相矛盾：

MSDN Worksheet.Cells

在MSDN文档中,他们给出了一个示例,在该示例中首先列出该行,然后列出该列.

所以我的问题是…这是正确的吗？
行应该在第一位还是列在第一位？
当我修改我的代码以使其与MSDN文档一致时,突出显示的单元格将被转置.

解决方法:

如果我对您的理解正确,那么当您使用cells [1] [2]时,则表示A2.在这种情况下,列首先出现,然后是行.如果将其写为单元格[1,2],则将得到B2.在这种情况下,Row首先出现,然后是Column.

在Excel-VBA中相同.立即窗口中的？Cells(1)(2).address给出$A $2和？Cells(1,2).address给出$B $1如果您觉得我不理解您的查询,请为我重新措辞. ..

这是测试它的完整代码.
