winform Windows Installer 安装后 程序运行修改任务栏图标 代码

在Windows Form应用程序中，如果你想要安装完成后自定义Windows Installer (MSI) 安装包的任务栏图标，通常需要在安装过程中设置快捷方式，并指定其图标。这通常涉及创建一个`Shortcut`对象并关联到你的程序文件。以下是一个简化的示例，展示了如何在C#中使用Wix Toolset（WiX脚本语言）来创建自定义 MSI 包：

<!-- WiX Setup Project (.wxs) Example -->
<Property Id="TARGETDIR" Value="$(var.MyProjectDir)\$(ProgramFilesFolder)" />
<Directory Id="TARGETDIR">
    <Directory Id="ProgramFilesFolder">
        <Directory Id="MyCompanyAppsFolder">
            <!-- Install the application executable and its icon file -->
            <Component Id="MyAppExe" Guid="...">
                <File Id="MyApp.exe" Name="MyApp.exe" Source="MyApp.exe" KeyPath="yes" />
                <!-- Create a shortcut to launch the app -->
                <CreateShortCut Id="MyAppShortcut"
                                Directory="TARGETDIR\MyCompanyAppsFolder"
                                Target="[INSTALLPATH]MyApp.exe"
                                WorkingDirectory="."
                                Icon="icon.ico" /> <!-- Replace 'icon.ico' with your desired icon file -->
            </Component>
        </Directory>
    </Directory>
</Directory>

<!-- You can set a custom taskbar icon using the following in the InstallUISequence section -->
<InstallUISequence>
    <!-- ... -->
    <InstallExecute Sequence='90'>CustomAction TaskbarIconSet</InstallExecute>
    <ProgressText Action='TaskbarIconSet'>Setting taskbar icon...</ProgressText>
</InstallUISequence>

<!-- Add this CustomAction to set the taskbar icon after installation -->
<CustomAction Id="TaskbarIconSet" BinaryKey="WixCA" DllEntry="CAQuietExec" Return="check" Execute="deferred" Impersonate="no">
    <Param Name="CmdLine" Value='"[TARGETDIR]\MyCompanyAppsFolder\MyAppShortcut.lnk" /taskschd::Start "" /tskparam:icon=[ProductName].ico /tray"'>
    <!-- Replace '[ProductName]' with your actual product name and '[ProductName].ico' with the correct icon filename -->
    </Param>
</CustomAction>

记得将上述代码中的`...`替换为你实际的项目信息、文件路径和图标名称。安装完成后，当用户双击任务栏快捷方式时，会显示你指定的图标。
