做了一段时间的Silverlight开发，已经厌倦了Silverlight默认的千篇一律的初始屏幕，突然想打造一个自己的Silverlight初始屏幕。网上虽然有一些资料，但是大多跟MSDN上的内容差不多；MSDN对Silverlight初始屏幕也有比较全面的讲解，不过有点太理论化，没有具体的实例；MSDN上唯一的一个实例就是如何：定义简单的 Silverlight 初始屏幕，这个实例又过于简单，达不到想要的效果；因此还是得自己摸索，上网查资料，通过一段时间的努力，终于搞定了，下面把我制作厨师屏幕的步骤介绍一下：
一、创建Silverlight Web应用程序
这里我使用的是VS2010，新建一个Silverlight 应用程序，在d出的对话框中选择在新网站中承载Silverlight，如图：
二、添加初始屏幕页面
初始屏幕页面不包含在Silverlight项目中，而是需要包含在承载它的Web项目中，否则，在下载数据包本身的过程中，将无法使用该页。
添加初始屏幕页面，需要进行如下 *** 作：
在解决方案资源浏览器中右键单击 SplashScreen.SL4.Web，然后选择"属性"。单击"Web"选项卡。将"启动 *** 作"的默认页从SpalshScreen.SL4TestPage.aspx改为 SpalshScreen.SL4TestPage.@R_419_6832@，其实用aspx也可以，不过没必要这么做。
在解决方案资源浏览器中右键单击 SplashScreenSource.Web，然后依次选择"添加"、"新建项"。在"类别"树视图中选择"Silverlight"选项。选择"Silverlight Jscript 页"选项。将页面命名为 SplashScreen.xaml。单击"添加"。
打开SplashScreen.xaml页面，需要注意的是，默认生成布局是Canvas，这个控件大家应该都熟悉，用它做布局容器，需要设置Canvas内元素的位置，我们一般希望初始屏幕的进度条在屏幕中央，而且对于不同分辨率下达到一样的效果；事实上，MSDN上和VS模板里都是针对Sl1.0的情况，对于2.0以上版本，已经能用GrID作为布局容器了，因此修改SplashScreen.xaml的内容如下：
[@R_419_6832@] view plain copy <GrID xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:name="parentCanvas" > </GrID>
在解决方案资源浏览器中选中SplashScreen.xaml，在属性选项卡选择生成 *** 作为内容，这一点很重要，否则在发布后会看不到效果的。
三、创建进度条资源
大多数Silverlight初始屏幕都需要一个进度条显示应用程序加载进度，MSDN示例中是一种显示初始屏幕进度条的方式，这里我要使用另一种方法，先看看效果：
这里我使用文字做的效果，这里我可不是直接用的TextBlock，TextBlock写不出这种效果的字，当然也不是普通图片，而是通过Path路径画的向量图。注意在初始屏幕页面中最好不要用普通图片做为背景或者显示，普通图片是作为资源被异步加载的，因此可能会导致进度已经开始了，但是图片都没显示出来；向量图片会随初始页面显示一同呈现出来，动画也是一样，最好用Xaml来写动画。
那么画矢量图的文字是不是很麻烦呢，大家应该都安装了Expression Studio，其中有一个软件叫Expression Design，用它做矢量图就很容易了，步骤如下：
打开Expression Design，依次选择文件、新建，文档大小没关系，只要能显示下你要显示的文字就可以了，点击确定。
在左侧快捷 *** 作栏中选择文本，在画板中间输入文字Silverlight，然后选中文字，在属性对话框中选择文字的字体为Jokerman，大小60磅，接着调整字体颜色和渐变，如图
OK，字体已经做好了，现在我们将它导出为Xaml。在左侧快捷 *** 作栏点击选择按钮，然后选中文本框，右键选择导出，导出属性选择XAML Silverlight/WPF4 画布，文本选择路径，最后选择导出位置，然后点全部导出。这样特效文字就做好了，将导出的Xaml内容复制到初始屏幕页面中，可能需要稍做调整。
光文字内容不能创建出进度条效果，需要在文字上添加一个遮挡的层，让遮挡层的宽度随进度增加而变小，即可实现文字逐渐显示的进度；要注意的控件宽度默认从右向左进行收缩的，因此需要对遮挡层进行180度旋转，可以围绕中心旋转，也可以绕原点旋转，然后平移 最后添加2个TextBlock标题，一个显示加载中的文字，一个用数字显示进度，整个初始屏幕布局的代码如下： copy GrID

四、使用Js控制显示加载进度
返回到 SpalshScreen.SL4TestPage.@R_419_6832@进行编辑，首先需要引用之前创建的 JavaScript 文件。在紧挨 @R_419_6832@ 中 head 元素的后面，添加以下内容：
copy script type="text/JavaScript" src="splashscreen.Js">script>
接着在SplashScreenSourceTestPage.@R_419_6832@ 的 Silverlight object 元素区域进行编辑。请注意，当前已存在大量作为 object 的子元素的"params"元素。现在将要添加几个 params 元素以添加您的自定义初始屏幕信息。添加以下 params 元素：
最后打开SplashScreen.Js文件，清空里面的内容，复制以下代码到SplashScreen.Js中：
五、运行程序
到这里所有工作就做完了，可以调试运行程序查看效果，不过可能由于加载过快而看不到过程，这时我们可以在Silverlight应用程序里添加一个外部文件，20M左右大小就可以了，不要太大，将生成属性设置为嵌入的资源，这样Silverlight应用程序就有足够大而且可以看到动画加载过程
