C# 使用 Microsoft.Office.Interop.Excel 添加新的 SERIES 与其他工作表的范围

Question

我希望 Excel 看起来像这样：

我必须尝试创建一个工作簿和工作表，而不是添加一个图表并从另一个图表中获取范围以进行下一步我想在一个图表中显示多个看起来像这样的线图但现在，我只是不知道这该怎么做

这是我的代码和我尝试过的：

但我有一个错误

System.Runtime.InteropServices.COMException: 'Exception from HRESULT: 0x800A03EC'

我尝试过其他方法，但在所有情况下我都遇到了这个错误......
我没有找到任何例子......而且我认为在随机尝试中我永远不会得到正确的方法来做到这一点......

namespace EXCELTEST
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            Microsoft.Office.Interop.Excel.Application xlApp;
            xlApp = new Microsoft.Office.Interop.Excel.Application
            {
                DisplayAlerts = true,
                Visible = true
            };
            Workbook reportWorkbook = xlApp.Workbooks.Add();
            Worksheet reportWorksheet = reportWorkbook.Worksheets.Add();

            reportWorksheet.Cells[1, "B"] = "Volt";
            reportWorksheet.Cells[1, "A"] = "Capacity";

            int c = 0;
            int i = 2;
            double v = 2.5;
            double vDiff = 0.050;
            while ( i < 30 )
            {

                reportWorksheet.Cells[i, "B"] = v;
                reportWorksheet.Cells[i, "A"] = c;

                v += vDiff;
                vDiff -= 0.001;
                c += 10;
                i++;
            }

            Worksheet ChartWorksheet = reportWorkbook.Worksheets.Add();
            Range chartRange;
            ChartObjects xlCharts = (ChartObjects)ChartWorksheet.ChartObjects(Type.Missing);
            ChartObject myChart = (ChartObject)xlCharts.Add(10, 80, 300, 250);
            Chart chartPage = myChart.Chart;
            chartRange = ChartWorksheet.get_Range("'Sheet2'!A1", "'Sheet2'!B29");
            chartPage.SetSourceData(chartRange);
            //chartPage.ChartType = Excel.XlChartType.xlLine;
            chartPage.ChartType = XlChartType.xlLine;


        }
    }
}

Answer 1

而不是使用这个

chartRange = ChartWorksheet.get_Range("'Sheet2'!A1", "'Sheet2'!B29");

使用以下代码选择范围

chartRange = reportWorksheet.get_Range("A1","B39");

你应该让它工作..

编辑

要将 Volt 放在一边，请尝试以下操作：

Worksheet ChartWorksheet = reportWorkbook.Worksheets.Add();
ChartWorksheet = reportWorkbook.ActiveSheet;
ChartObjects xlCharts = (ChartObjects)ChartWorksheet.ChartObjects(Type.Missing);
ChartObject myChart = (ChartObject)xlCharts.Add(10, 80, 300, 250);
Chart chartPage = myChart.Chart;
SeriesCollection oSeriesCollection = (SeriesCollection)myChart.Chart.SeriesCollection();
Series Data = oSeriesCollection.NewSeries();
Data.XValues = reportWorksheet.get_Range("A2", "A29");
Data.Values = reportWorksheet.get_Range("B2", "B29");
Data.Name = "Volt";
chartPage.ChartType = XlChartType.xlLineMarkers;

渲染的输出：
