參考中的錯誤

我不確定爲什麼參考文獻中有錯誤。 OxyPlot.Wpf.LineSeries到OxyPlot.Series.SeriesSystem.Collections.ObjectModel.Collection.Add(OxyPlot.Axes.Axis)的最佳重載方法匹配有一些無效參數。參考中的錯誤

這聽起來像是你遇到了一些不同的命名空間的問題。我不能說我完全理解你在嘗試什麼，所以這可能不會給你想要的結果，但是我可以使用以下命名空間（通過nuget安裝OxyPlot.Wpf）來編譯代碼：

using OxyPlot; 
using OxyPlot.Axes; 
using OxyPlot.Series;

可能是這種情況，如果您發現您在名稱空間中發現了某些特定行爲，那麼這對您沒有任何幫助。
