UIElement.Projection只在Silverlight，而不是在WPF？ [英] UIElement.Projection only in Silverlight and not in WPF?

问题描述

我下载了一个样本code从这里开始： HTTP：//gallery.ex$p$pssion.microsoft.com/ShowHideWithFlip

现在我的问题是，我使用WPF的家伙是使用Silverlight。

我还以为他们都使用.NET 4，但我发现有.NET 4，并有.NET Silverlight的totla指出错误的东西..

我得到这个错误：

 System.Windows.UIElement'不包含'投射'，没有扩展方法'投射'接受第一种类型System.Windows.UIElement的说法可能是一个定义（是否缺少using指令或程序集引用？）
 

我刚刚找到了原因，那家伙正在使用.NET的Silverlight和我使用.NET 4。

Silverlight的： 的http://msdn.microsoft.com/en-us/library/system.windows.uielement(v=VS.95).aspx

.NET 4： http://msdn.microsoft。 COM / EN-US /库/ system.windows.uielement.aspx

有一个解决方案？

我觉得WPF和Silverlight是相同的（的 http://msdn.microsoft.com/en-us/library/ff921107（V = pandp.20）的.aspx ）

这是我的problam但我不能弄清楚如何使用ViewPort3D。 这里的code中的一部分：

 如果（showElement.Projection == NULL）
        {
            showElement.Projection =新PlaneProjection（）;
            showElement.RenderTransformOrigin =新的点（0.5，.5）;
        }

        如果（hideElement.Projection == NULL）
        {
            hideElement.Projection =新PlaneProjection（）;
            hideElement.RenderTransformOrigin =新的点（0.5，.5）;
        }

        mainStoryboard =新的故事板（）;

        BackEase hide_ease =新BackEase（）{EasingMode = EasingMode.EaseOut，振幅= 0.2};

        // 显示
        PlaneProjection showPP =新PlaneProjection（）;
        CompositeTransform showCT =新CompositeTransform（）;
 

解决方案

不幸的是，这并不在WPF 3.5或4存在的，没有。只有在Silverlight中。但是，你当然可以推出自己的3-D WPF中。这里是一个例子的3-D旋转控制。下面是微软在 Viewport3D 的文档。

I downloaded a sample code from here: http://gallery.expression.microsoft.com/ShowHideWithFlip

Now my problem is that i'm using WPF and the guy is using Silverlight..

I thought they are both using .NET 4 but i found out there is ".NET 4" and there is ".NET for Silverlight" totla diffrent things..

i get this error:

'System.Windows.UIElement' does not contain a definition for 'Projection' and no   extension method 'Projection' accepting a first argument of type 'System.Windows.UIElement' could be found (are you missing a using directive or an assembly reference?)

I just found out why, the guy is using .NET for Silverlight and i'm using .NET 4.

Silverlight: http://msdn.microsoft.com/en-us/library/system.windows.uielement(v=VS.95).aspx

.NET 4: http://msdn.microsoft.com/en-us/library/system.windows.uielement.aspx

There is a solution for this?

I thought WPF and Silverlight is kinde of the same ( http://msdn.microsoft.com/en-us/library/ff921107(v=pandp.20).aspx )

I just found this: http://social.msdn.microsoft.com/Forums/en/wpf/thread/9acb712a-b592-49e7-83a1-e3ee7ff03014

This is my problam but i cant figure how to use the ViewPort3D. here is the part of the code:

        if (showElement.Projection == null)
        {
            showElement.Projection = new PlaneProjection();
            showElement.RenderTransformOrigin = new Point(.5, .5);
        }

        if (hideElement.Projection == null)
        {
            hideElement.Projection = new PlaneProjection();
            hideElement.RenderTransformOrigin = new Point(.5, .5);
        }

        mainStoryboard = new Storyboard();

        BackEase hide_ease = new BackEase() { EasingMode = EasingMode.EaseOut, Amplitude = 0.2 };

        // Show           
        PlaneProjection showPP = new PlaneProjection();
        CompositeTransform showCT = new CompositeTransform();

解决方案

Unfortunately this doesn't exist in WPF 3.5 or 4, no. Only in Silverlight. However, you can certainly roll your own 3-D in WPF. Here's one example of 3-D rotated controls. Here's Microsoft's doc on Viewport3D.
