大佬教程收集整理的这篇文章主要介绍了c# – 在Taskdialog中使用隐藏的安全图标，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

我试图在TaskDialog消息框中显示安全成功图标(带蓝色背景).这不是TaskDialogStandarDicon的枚举值之一.参考： http://dotnet.dzone.com/articles/using-new-taskdialog-winapi.

如何将这些非标准值分配给((TaskDialog)发送者).Icon？它甚至可以在C#中使用吗？ C#

任何指针都会非常有用.

问候,

解决方法

我想你需要自己从comctl32.dll导入 TaskDialog函数：

static class TaskDialogWrapper
{
    [DllImport("comctl32.dll",CharSet = CharSet.Unicode,EntryPoint = "TaskDialog")]
    static extern int TaskDialog(IntPtr hWnd,IntPtr hInstance,String pszWindowtitle,String pszMaininstruction,String pszContent,TaskDialogCommonButton dwCommonButtons,IntPtr pszIcon,out IntPtr pnButton);

    public static TaskDialogCommonButton Show(IntPtr handle,IntPtr instance,String title,String instructiontext,String content,TaskDialogCommonButton commonButtons,TaskDialogCommonIcon commonIcon)
    {
        IntPtr resultButton;
        if (TaskDialog(handle,instance,title,instructiontext,content,commonButtons,new IntPtr((int)commonIcon),out resultButton) != 0)
            throw new InvalidoperationException();
        return (TaskDialogCommonButton)resultButton;
    }
}

[Flags()]
enum TaskDialogCommonButton
{
    Ok = 0x1,Yes = 0x2,No = 0x4,Cancel = 0x8,Retry = 0x10,Close = 0x20
}

enum TaskDialogCommonIcon
{
    ShieldGrey = 65527,ShieldOk = 65528,ShieldError = 65529,ShieldWarning = 65530,ShieldBlue = 65531,Shield = 65532,Information = 65533,Error = 65534,Warning = 65535,}

要从文件中使用您自己的图标,您需要导入TaskDialogIndirect.

(顺便说一下,我为TaskDialogCommonIcon找到了许多其他有趣的图标样式.你可以添加例如：

enum TaskDialogCommonIcon
{
    None = 0,Sheet = 2,ExplorerFolderOpen = 3,ExplorerFolderFlat = 5,ExplorerFolderLeft = 6,Search = 8,ExplorerFolderClosed = 10,ExplorerGames = 14,Application = 15,TransparentSpace = 17,ExplorerSearch = 18,TextFile = 19,Letter = 20,Picture = 21,Diashow = 103,// ...
}
