第一步：自定义一个Button的样式
1.新建一个xaml文件，在其中自定义好自己的Resources
这个Resource 的根节点是
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"></ResourceDictionary>
2.然后在根节点中写入自己要定义的样式，
注意，在对应特定控件的样式中，要写入 TargetType 对应于要设置样式的控件，如：
TargetType="{x:Type Button}"，并且对样式写上x:key= 以便查找：
入下面一个例子：
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:Microsoft_Windows_Themes="clr-namespace:Microsoft.Windows.Themes;assembly=PresentationFramework.Classic"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Style x:Key="GlassYButton" TargetType="{x:Type Button}">

2.
第二步：在项目的配置文件 App.xaml 中配置 自定义Resources
在 App.xml根节点下面建立一个 <Application.Resources>，其中定义ResourceDictionary节点
在其中配置自己定义的Resources，例如：
<Application x:Class="PaperOfficerPro.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" StartupUri="MainWindow.xaml">
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Resource/ButtonResource.xaml"></ResourceDictionary>
<ResourceDictionary Source="Resource/ExpanderStyleResource.xaml"></ResourceDictionary>
<ResourceDictionary Source="Resource/GlassButtonStyle.xaml"></ResourceDictionary>
<ResourceDictionary Source="Resource/DataGridResource.xaml"></ResourceDictionary>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
</Application>
第三步：在页面的后台写程序动态生成Button,
这里的实例是，检索数据库，根据检索的数据动态生成一个按钮，按钮的个数是检索出来的数据的条数
例如：
private void initCourseButton()
{
PaperDBHelper.ConnectDB();
String sql = "select keyID ,courseID,courseName from course order by keyID ";
DataSet courseDS = PaperDBHelper.GetDataSet(CommandType.Text, sql, null);
DataTable dt = courseDS.Tables[0];
for (int i = 0; i < dt.Rows.Count; i++) //for循环检索出来的数据，生成Button
{
Button button = new Button();
button.Content = dt.Rows[i]["courseName"]; //Button按钮上的显示内容为数据库中的一个字段值
button.Width = 80;
button.Height = 50;
button.Margin = new Thickness(0 + i * 80, 507, 560 - i * 120, 4);//动态生成Button的位置
button.Name = "button" + (i + 1);//动态生成Button的Name
button.SetResourceReference(StyleProperty, "GlassYButton");//将自定义的样式赋值给Button
//的相应属性，第一个参数是第一步中的Resource是定义的Button的Style，因此第一个参数为StyleProperty
//意思是赋值给style这个属性，第二个参数是样式中的x:key的值
button.Click += new RoutedEventHandler(btnEvent_Click);//为动态生成的Button添加事件
this.ButtonGrid.Children.Add(button);//注意，最后要将自定义的Button控件加入到页面中包含它
//的容器中
this.ButtonGrid.RegisterName("button" + (i + 1), button);//注册button的名称
}
}
