如何创建 PointPairLists 列表？

Question

我有一些 PointPairLists，我想将它们添加到列表；但我遇到异常索引超出范围：AllPhiLines[0].Add(Quartz[0]);

我尝试了以下代码：

        PointPairList Quartz = new PointPairList(7000);
        PointPairList Calcite = new PointPairList(7000);
        PointPairList Dolomite = new PointPairList(7000);
        double[] XQuartz = { -2.05E+00, -1.05E+00, -4.01E-01, 4.25E-01, 1.31E+00, 2.08E+00 };
        double[] YQuartz = {2.64E+00 ,2.62E+00 ,2.61E+00 ,2.59E+00 ,2.57E+00 ,2.55E+00 };
        double[] XCalcite = {-2.83E-01 ,7.19E-01 ,1.90E+00 ,2.96E+00 ,4.02E+00 ,5.02E+00 ,6.03E+00 ,7.09E+00 };
        double[] YCalcite = {2.71E+00 ,2.69E+00 ,2.68E+00 ,2.66E+00 ,2.64E+00 ,2.62E+00 ,2.60E+00 ,2.58E+00 };
        double[] XDolomite = {1.31E+00 ,2.67E+00 ,4.02E+00 ,5.32E+00 ,6.62E+00 ,7.79E+00 ,9.03E+00 };
        double[] YDolomite = {2.88E+00 ,2.86E+00 ,2.84E+00 ,2.82E+00 ,2.80E+00 ,2.78E+00 ,2.76E+00 };
        for (int i=0; i<6; i++)
        {
            Quartz.Add(XQuartz[i], YQuartz[i]);
        }
        for (int i=0; i<8; i++)
        {
            Calcite.Add(XCalcite[i], YCalcite[i]);
        }
        for (int i=0; i<7; i++)
        {
            Dolomite.Add(XDolomite[i], YDolomite[i]);
        }
        List<PointPairList> AllPhiLines = new List<PointPairList>();
        AllPhiLines[0].Add(Quartz[0]);
        AllPhiLines[0].Add(Calcite[0]);
        AllPhiLines[0].Add(Dolomite[0]);
        LineItem AllPhiLinesCurve = pane1.AddCurve("Phi", AllPhiLines[0], Color.Gray, SymbolType.None)

希望大家帮我解决一下

AllPhiLines 还不包含任何值，因此您无法解决项目 0。创建 AllPhiLines 之后，您首先必须向其中添加一个项目，例如

AllPhiLines.Add(new PointPairList(7000));
