背水一战 Windows 10 之 其它
- 通过 Windows.System.Profile 命名空间下的类获取信息
- 查找指定类或接口的所在程序集的所有子类和子接口
示例
1、演示如何通过 Windows.System.Profile 命名空间下的类获取信息
Information/ProfileInfo.xaml
<Page
x:Class="Windows10.Information.ProfileInfo"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:Windows10.Information"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"> <Grid Background="Transparent">
<StackPanel Margin="10 0 10 10"> <TextBlock Name="lblMsg" TextWrapping="Wrap" Margin="0 10 10 10" /> </StackPanel>
</Grid>
</Page>
Information/ProfileInfo.xaml.cs
/*
* 演示如何通过 Windows.System.Profile 命名空间下的类获取信息
*
* 主要可获取到设备类型，系统版本号等
*/ using System;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls; using Windows.System.Profile; namespace Windows10.Information
{
public sealed partial class ProfileInfo : Page
{
public ProfileInfo()
{
this.InitializeComponent(); this.Loaded += ProfileInfo_Loaded;
} private void ProfileInfo_Loaded(object sender, RoutedEventArgs e)
{
// 获取设备类型，目前已知的返回字符串有：Windows.Mobile, Windows.Desktop, Windows.Xbox
lblMsg.Text = string.Format("DeviceFamily: {0}", AnalyticsInfo.VersionInfo.DeviceFamily);
lblMsg.Text += Environment.NewLine; // 获取系统版本号，一个长整型值
lblMsg.Text += string.Format("DeviceFamilyVersion: {0}", AnalyticsInfo.VersionInfo.DeviceFamilyVersion);
lblMsg.Text += Environment.NewLine; // 将长整型的系统版本号转换为 major.minor.revision.build 的方式
string versionString = AnalyticsInfo.VersionInfo.DeviceFamilyVersion;
ulong version = ulong.Parse(versionString);
ulong v1 = (version & 0xFFFF000000000000L) >> ;
ulong v2 = (version & 0x0000FFFF00000000L) >> ;
ulong v3 = (version & 0x00000000FFFF0000L) >> ;
ulong v4 = (version & 0x000000000000FFFFL);
string v = $"{v1}.{v2}.{v3}.{v4}"; lblMsg.Text += string.Format("DeviceFamilyVersion(major.minor.revision.build): {0}", v);
lblMsg.Text += Environment.NewLine; // 获取当前的“向 Microsoft 发送你的设备数据”的收集等级。在“设置”->“隐私”->“反馈和诊断”中配置（Security, Basic, Enhanced, Full）
lblMsg.Text += string.Format("PlatformDiagnosticsAndUsageDataSettings.CollectionLevel: {0}", PlatformDiagnosticsAndUsageDataSettings.CollectionLevel);
lblMsg.Text += Environment.NewLine; // 检查当前配置是否允许指定级别的信息收集
lblMsg.Text += string.Format("PlatformDataCollectionLevel.Full: {0}", PlatformDiagnosticsAndUsageDataSettings.CanCollectDiagnostics(PlatformDataCollectionLevel.Full));
lblMsg.Text += Environment.NewLine; // 在“设置”->“隐私”->“反馈和诊断”中配置的“向 Microsoft 发送你的设备数据”发生变化时触发的事件
PlatformDiagnosticsAndUsageDataSettings.CollectionLevelChanged += PlatformDiagnosticsAndUsageDataSettings_CollectionLevelChanged;
} private async void PlatformDiagnosticsAndUsageDataSettings_CollectionLevelChanged(object sender, object e)
{
await Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal, () =>
{
lblMsg.Text += string.Format("PlatformDiagnosticsAndUsageDataSettings.CollectionLevel: {0}", PlatformDiagnosticsAndUsageDataSettings.CollectionLevel);
lblMsg.Text += Environment.NewLine; lblMsg.Text += string.Format("PlatformDataCollectionLevel.Full: {0}", PlatformDiagnosticsAndUsageDataSettings.CanCollectDiagnostics(PlatformDataCollectionLevel.Full));
lblMsg.Text += Environment.NewLine;
});
}
}
}
2、用于查找指定类或接口的所在程序集的所有子类和子接口
Tools/FindSubClass.xaml
<Page
x:Class="Windows10.Tools.FindSubClass"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:Windows10.Tools"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"> <Grid Background="Transparent">
<ScrollViewer Margin="10 0 10 10">
<StackPanel Name="root" Margin="5"> <Button Name="btnFind" Content="查找指定类或接口的所在程序集的所有子类或子接口" Margin="1 5 1 20" Click="btnFind_Click" /> </StackPanel>
</ScrollViewer>
</Grid>
</Page>
Tools/FindSubClass.xaml.cs
/*
* 用于查找指定类或接口的所在程序集的所有子类和子接口
*/ using System;
using System.Reflection;
using System.Collections.Generic;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;
using System.Linq; namespace Windows10.Tools
{
public sealed partial class FindSubClass : Page
{
public FindSubClass()
{
this.InitializeComponent();
} private void btnFind_Click(object sender, RoutedEventArgs e)
{
// 这样不行
// Type type = Type.GetType("Windows.UI.Xaml.Controls.Button"); Type type = typeof(Windows.UI.Xaml.UIElement); List<Type> subTypes = GetSubTypes(type);
AddWrapGrid(subTypes);
} private void AddWrapGrid(List<Type> subTypes)
{
VariableSizedWrapGrid wrapGrid = CreateWrapGrid();
root.Children.Add(wrapGrid); foreach (Type type in subTypes)
{
Button button = CreateButton(type);
wrapGrid.Children.Add(button);
}
} private void Button_Click(object sender, RoutedEventArgs e)
{
FrameworkElement button = sender as FrameworkElement;
Type type = button.Tag as Type; int index = ;
// 删除被选中按钮的所属容器，以及此容器之后的所有控件
if (button.Parent.GetType() == typeof(VariableSizedWrapGrid))
index = root.Children.IndexOf(button.Parent as UIElement);
// 删除被选中按钮，以及此按钮之后的所有控件
else
index = root.Children.IndexOf(button);
while (root.Children.Count > index)
{
root.Children.RemoveAt(root.Children.Count - );
} // 将被选中按钮添加到根容器
Button buttonNew = CreateButton(type);
root.Children.Add(buttonNew);
root.Children.Add(new Grid() { Height = }); // 将被选中类的所有子类添加到根容器
List<Type> subTypes = GetSubTypes(type);
AddWrapGrid(subTypes);
} private VariableSizedWrapGrid CreateWrapGrid()
{
VariableSizedWrapGrid wrapGrid = new VariableSizedWrapGrid();
wrapGrid.Orientation = Orientation.Vertical;
wrapGrid.ItemWidth = ;
wrapGrid.HorizontalAlignment = HorizontalAlignment.Stretch; return wrapGrid;
} private Button CreateButton(Type type)
{
Button button = new Button();
button.Content = type.ToString();
button.Margin = new Thickness();
button.Tag = type;
button.Click += Button_Click; return button;
} // 获取儿子类，孙子及以下级别不会返回
private List<Type> GetSubTypes(Type type)
{
List<Type> subTypes = new List<Type>(); Type[] assemblyTypes = type.GetTypeInfo().Assembly.GetTypes(); foreach (Type t in assemblyTypes)
{
if (type.GetTypeInfo().IsInterface)
{
if (t.GetInterfaces().Contains(type))
{
subTypes.Add(t);
}
}
else
{
if (t.GetTypeInfo().BaseType == type)
{
subTypes.Add(t);
}
}
} subTypes = subTypes.OrderBy(p => p.FullName).ToList(); return subTypes;
}
}
}
OK
