您好我正在使用我从codeplex.com/dynamicdatadisplay获得的动态数据显示库。我将我的副本保存在根目录中,并将对DynamicDataDisplay.dll文件的DLL的引用添加到我的项目中。然而,xaml无法识别ChartPlotter并且在命名空间“http://research.microsoft.com/DynamicDataDisplay/1.0”中说“名称”ChartPlotter“。有没有人知道这是什么问题?
XAML:
<Window x:Class="WpfApplication3.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d3="http://research.microsoft.com/DynamicDataDisplay/1.0"
Title="MainWindow" Height="350" Width="525">
<Grid>
<d3:ChartPlotter Name="plotter" Margin="10,10,20,10">
<d3:ChartPlotter.HorizontalAxis>
<d3:HorizontalDateTimeAxis Name="dateAxis"/>
</d3:ChartPlotter.HorizontalAxis>
<d3:ChartPlotter.VerticalAxis>
<d3:VerticalIntegerAxis Name="countAxis"/>
</d3:ChartPlotter.VerticalAxis>
<d3:Header FontFamily="Arial" Content="Bug Information"/>
<d3:VerticalAxisTitle FontFamily="Arial" Content="Count"/>
<d3:HorizontalAxisTitle FontFamily="Arial" Content="Date"/>
</d3:ChartPlotter>
</Grid>
</Window>

可能是“锁定”的dll问题。必须解锁DynamicDataDisplay.dll(检查其属性)。 相关主题:WPF assembly reference missing - project still building
