Question

我最近偶然发现了这种奇怪的行为，同时试图从excel中获取样式信息，尤其是边框颜色。

使用Microsoft.Office.Interop.Excel 15.0.0.0 和Excel 2010

我将9个相邻单元格中的边框颜色（xlDiagonalUp）和样式分别设置为红色和连续线。当通过查询范围要求返回信息时，颜色信息会模糊消失

这是重现该问题的单元测试

[TestCase]
public void TestExcelStuff()
{
    var excel = new Application();
    var wb = (_Workbook) (excel.Workbooks.Add(Missing.Value));
    var sht = wb.ActiveSheet;
    // Setup
    for (int i = 0; i < 3; i++)
    {
        for (int k = 0; k < 3; k++)
        {
            sht.Cells[2 + i, 2 + k].Borders[XlBordersIndex.xlDiagonalUp].Color = XlRgbColor.rgbRed;
            sht.Cells[2 + i, 2 + k].Borders[XlBordersIndex.xlDiagonalUp].LineStyle = XlLineStyle.xlContinuous;
        }
    }
    // test
    for (int i = 0; i < 3; i++)
    {
        for (int k = 0; k < 3; k++)
        {
            Console.WriteLine($"Setting Cell {2+i},{2+k}");
            var lineColor = ColorTranslator.FromOle((int)sht.Cells[2 + i, 2 + k].Borders[XlBordersIndex.xlDiagonalUp].Color);
            // Works: the Borderline is red and continuous
            Assert.AreEqual(Color.Red, lineColor);
            Assert.AreEqual((int)XlLineStyle.xlContinuous, sht.Cells[2 + i, 2 + k].Borders[XlBordersIndex.xlDiagonalUp].LineStyle);

        }
    }
    var rng = sht.Range[sht.Cells[2, 2], sht.Cells[4, 4]];
    // works: continous line
    Assert.AreEqual((int)XlLineStyle.xlContinuous, rng.Borders[XlBordersIndex.xlDiagonalUp].LineStyle);
    // for your eyes
    excel.Visible = true;           
    var lineColor1 = ColorTranslator.FromOle((int) rng.Borders[XlBordersIndex.xlDiagonalUp].Color);           
    // does not Work: the Borderline is black! but why?  
    Assert.AreEqual(Color.Red, lineColor1);
}

错误或功能？

Excel单元格具有xlDiagonalUp边框颜色，但同一单元格的范围没有。虫子？
