问题:使用.NET 4将程序最小化到系统托盘的最简单方法是什么?
答案:
使用.NET 4将程序最小化到系统托盘的最简单方法是使用Microsoft's Taskbar API。以下是实现此操作的步骤:
App.xaml.cs
文件中,添加以下代码:using System.Runtime.InteropServices;
using Microsoft.Windows.Shell;
// 导入必要的命名空间
[assembly: ApplicationActivationManager(ActivationType = ApplicationActivationMode.SystemState)]
[assembly: ApplicationShutdownManager]
namespace YourNamespace
{
class Program : ApplicationActivationManager
{
protected override bool OnStartup(EventArgs e)
{
// 获取任务栏的ShellFolder
ShellFolder taskbarFolder = ShellFolder.FromParsingName(ParsingName);
// 创建一个ShellLink对象,并设置目标路径
ShellLink shellLink = new ShellLink();
shellLink.TargetPath = Application.ExecutablePath;
// 将ShellLink对象添加到任务栏文件夹
taskbarFolder.Items.Add(shellLink);
return true;
}
protected override void OnShutdown(ShutdownEventArgs e)
{
// 从任务栏文件夹中移除ShellLink对象
ShellFolder taskbarFolder = ShellFolder.FromParsingName(ParsingName);
taskbarFolder.Items.Remove(shellLink);
base.OnShutdown(e);
}
}
}
App.xaml
文件中,设置应用程序的标题和图标:<Application x:Class="YourNamespace.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:YourNamespace"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
xmlns:local1="clr-namespace:YourNamespace.Properties"
xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity"
xmlns:ei="http://schemas.microsoft.com/expression/2010/interactions"
xmlns:converter="clr-namespace:YourNamespace.Converters"
xsi:schemaLocation="http://schemas.microsoft.com/winfx/2006/xaml/presentation http://schemas.microsoft.com/winfx/2006/xaml/presentation.xsd">
<Application.Resources>
<local:LocalizedStringsConverter x:Key="LocalizedStringsConverter"/>
</Application.Resources>
</Application>
Resources
文件夹中创建一个名为LocalizedStringsConverter.cs
的类,并添加以下代码:
using System;
using System.Globalization;
using System.Windows.Data;
using System.Windows.Markup;
// 导入必要的命名空间
assembly: XmlnsDefinition("http://schemas.microsoft.com/winfx/2006/xaml/presentation", "YourNamespace")
assembly: XmlnsDefinition("http://schemas.microsoft.com/winfx/2006/xaml", "YourNamespace")
namespace YourNamespace
{
public class LocalizedStringsConverter : MarkupExtension, IValueConverter
{
public LocalizedStringsConverter()
{
// 设置为True以显示本地化字符串,False以显示原始字符串
IsIncluded = true;
}
public override object ProvideValue(IServiceProvider serviceProvider)
{
return this;
}
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
string text = value as string;
if (text == null)
return "";
// 从资源字符串中提取本地化字符串
string localizableText = Regex.Match(text, @"^\s*localizable:\s*(true|false)\s*").Groups[1].Value;
if (bool.
