如何将wpf的图像源属性设置为画布而不是图像url

看看这篇文章，我认为它描述了您试图实现的目标

基本上，您无法将图像源直接绑定到画布，因此这里的想法是将画布转换为图像，并使用该图像而不是画布本身

<Image Source"{StaticResource MyCanvas}"/>

公共类ErrorToConverter:IMultiValueConverter
{
公共对象转换（对象[]值，类型targetType，对象参数，System.Globalization.CultureInfo区域性）
{
字符串s=值[0]。ToString（）；
if（值！=null和值[0]！=null和值[0]！=dependencProperty.UnsetValue）
{
如果（值[0].ToString（）.ToLower（）包含（“警告”））
{
返回应用程序.Current.FindResource（“警告图标”）；
}
else if（值[0].ToString（）.ToLower（）.Contains（“致命”））
{
返回应用程序.Current.FindResource（“ErrorIcon”）；
}
}
返回应用程序.Current.FindResource（“BlankIcon”）；
}
公共对象[]转换回（对象值，类型[]目标类型，对象参数，System.Globalization.CultureInfo区域性）
{
抛出新的NotImplementedException（）；
}
}

它不能用图像来实现。因此，我创建了一个带有ContentControl的画布。现在，将内容属性ContentControl设置为转换器返回的相应路径资源。

您似乎有点困惑。。。您询问是否可以将

Image.Source

属性设置为

Canvas

对象，该属性的类型为

ImageSource

。我很确定你会知道你不能这么做，因为

Canvas

不是

ImageSource

然而，我认为您实际上想要了解的是如何从

参考资料

部分显示

画布

。如果这就是你想要的，那么有一个更简单的方法来做到这一点。。。您可以将其显示在

ContentControl

中，如下所示：

要使用图像控件显示图形，可以使用DrawingImage作为图像控件的源和要显示的图形。有关详细信息，请访问

而且您的路径必须使用表达式混合实现，这就是为什么它会显示额外的内容，比如path.RenderTransform.anyway，这两个代码的输出是相同的
