我必须在其中显示包含4个系列的图表。我能够使用我的数据来完成这项工作。 但是，当我开始更新数据列表时，它会给出一个解析错误（见下文）。 I.E它甚至在尝试“更新”图表之前给了我一个错误。哎呀，我甚至从等式中删除了图表，我仍然得到相同的解析错误。
以下是我的名单的宣布方式：
public partial class MainWindow : Window
{
List<KeyValuePair<double, double>> channel1List = new List<KeyValuePair<double, double>>();
List<KeyValuePair<double, double>> channel2List = new List<KeyValuePair<double, double>>();
List<KeyValuePair<double, double>> channel3List = new List<KeyValuePair<double, double>>();
List<KeyValuePair<double, double>> channel4List = new List<KeyValuePair<double, double>>();
List<List<KeyValuePair<double, double>>> rampsList = new List<List<KeyValuePair<double, double>>>();
在我的主要内容中，我得到了：
// DEFAULT CHANNEL 1 LIST
channel1List.Add(new KeyValuePair<double, double>(0, 0));
channel1List.Add(new KeyValuePair<double, double>(DMIN1, 0));
channel1List.Add(new KeyValuePair<double, double>(DMAX1, 100));
channel1List.Add(new KeyValuePair<double, double>(30, 100));
// DEFAULT CHANNEL 2 LIST
channel2List.Add(new KeyValuePair<double, double>(0, 0));
channel2List.Add(new KeyValuePair<double, double>(DMIN2, 0));
channel2List.Add(new KeyValuePair<double, double>(DMAX2, 100));
channel2List.Add(new KeyValuePair<double, double>(30, 100));
// DEFAULT CHANNEL 3 LIST
channel3List.Add(new KeyValuePair<double, double>(0, 0));
channel3List.Add(new KeyValuePair<double, double>(DMIN3, 0));
channel3List.Add(new KeyValuePair<double, double>(DMAX3, 100));
channel3List.Add(new KeyValuePair<double, double>(30, 100));
// DEFAULT CHANNEL 4 LIST
channel4List.Add(new KeyValuePair<double, double>(0, 0));
channel4List.Add(new KeyValuePair<double, double>(DMIN4, 0));
channel4List.Add(new KeyValuePair<double, double>(DMAX4, 100));
channel4List.Add(new KeyValuePair<double, double>(30, 100));
channel1List.RemoveAt(1);
channel1List.Insert(1, new KeyValuePair<double, double>(DMIN1, 0));
// DEFAULT LIST OF RAMPS
rampsList.Add(channel1List);
rampsList.Add(channel2List);
rampsList.Add(channel3List);
rampsList.Add(channel4List);
// DRAW DEFAULT CHART
rampsChart.DataContext = rampsList;
注意到2行“channel1.RemoveAt（1）...... / ...” 这些只是为了测试，我能够删除一个条目并用一个新的替换它。 这些系列每个只有4个点，我总是只需要更新第1项和第2项.0和3永远不会更新。
无论如何，上面的代码工作正常。它绘制了图表。没有解析错误。
现在，就像我说的那样，当用户移动滑块时我需要更新此图表。我为这个滑块设置了一个ValueChanged事件，可以很好地更新几个标签。
但如果我有相同的2行：
channel1List.RemoveAt(1);
channel1List.Insert(1, new KeyValuePair<double, double>(DMIN1, 0));
然后它在构建项目时没有给我任何错误，但是当我点击Start ...时给了我这个错误
PresentationFramework.dll中出现未处理的“System.Windows.Markup.XamlParseException”类型异常
我不知道为什么会这样做。
任何想法？ 谢谢 史蒂夫

我怀疑你的
channel1List.RemoveAt(1);
代码在您的
之前执行
channel1List.Add(new KeyValuePair<double, double>(0, 0)); channel1List.Add(new KeyValuePair<double, double>(DMIN1, 0)); channel1List.Add(new KeyValuePair<double, double>(DMAX1, 100)); channel1List.Add(new KeyValuePair<double, double>(30, 100));
导致此异常
确保执行顺序始终正确，例如通过从构造函数调用collection fill方法。
