嗨，我在windows窗体应用程序中使用条形图。它显示了条形图后面的网格，我的客户想要两个改变1：将网格从线改为点视图，网格样式应该是深灰色。你能提出你的建议吗？

 var chart = new Chart
        {
            Width = 500,
            Height = 360,
            AntiAliasing = AntiAliasingStyles.All,
            TextAntiAliasingQuality = TextAntiAliasingQuality.High
        };
chart.Series.Add("");
        foreach (String description in keyValue.Keys)
        {`enter code here`
            decimal value;
            keyValue.TryGetValue(description, out value);                
            chart.Series[0].Points.AddXY(description, value);                 
        }
chart.Series[0].Font = new Font(Constant.FontFamily, 15f, FontStyle.Regular, GraphicsUnit.Point);
        chart.Series[0].ChartType = System.Windows.Forms.DataVisualization.Charting.SeriesChartType.Bar;
        chart.Series[0].Color = System.Drawing.Color.FromArgb(169, 14, 59);
chart.ChartAreas.Add("CharArea");
        chart.ChartAreas[0].AxisY.LabelStyle.Font = new Font(Constant.FontFamily,15);
        chart.Legends.Add(new Legend());
        chart.Legends[0].Enabled = false;
 chart.Series[0].CustomProperties = "DrawingStyle=Cylinder";
       // chart.ChartAreas[0].AxisY.LabelStyle.Format = new Font(Constant.FontFamily, 9f, FontStyle.Regular, GraphicsUnit.Point);
        using (var chartimage = new MemoryStream())
        {
            chart.SaveImage(chartimage, ChartImageFormat.Png);
            return chartimage.GetBuffer();
        }

添加到.FromArgb方法的末尾0,0

总的来说，它看起来像。FromArgb（r，g，b，0，0）

我在代码中做了以下更改，它对我有效。对于虚线和灰色

chart.ChartAreas[0].AxisX.MajorGrid.LineDashStyle = System.Windows.Forms.DataVisualization.Charting.ChartDashStyle.DashDotDot;
chart.ChartAreas[0].AxisY.MajorGrid.LineDashStyle = System.Windows.Forms.DataVisualization.Charting.ChartDashStyle.DashDotDot;
chart.ChartAreas[0].AxisX.MajorGrid.LineColor = Color.DarkGray;
chart.ChartAreas[0].AxisY.MajorGrid.LineColor = Color.DarkGray;
