将系统图标分配给标签

Question

我目前正在开发c＃应用程序。我正在制作自己的自定义消息框，所以我想知道是否可以为标签指定一个默认系统图标（即您将在标准MessageBox上看到的图标之一）。

任何有关此事的帮助将不胜感激。

感谢

Answer 1

您可以System.Drawing中和System.Windows.Forms的互操作：

System.Drawing.Icon icon = System.Drawing.SystemIcons.Warning; 

BitmapSource bs = System.Windows.Interop.Imaging.CreateBitmapSourceFromHIcon(icon.Handle, Int32Rect.Empty, BitmapSizeOptions.FromEmptyOptions()); 

image1.Source = bs;

SLaks的解决方案可能是要走的最简单的方法。如果由于某种原因，你不想使用Windows窗体的功能，这是很容易实现自己：

public enum SystemIcons 
{ 
    Application = 32512, 
    Error = 32513, 
    Hand = Error, 
    Question = 32514, 
    Warning = 32515, 
    Exclamation = Warning, 
    Information = 32516, 
    Asterisk = Information, 
    WinLogo = 32517, 
    Shield = 32518, 
} 

public static ImageSource LoadSystemIcon(SystemIcons iconId) 
{ 
    string iconName = "#" + ((int)iconId); 
    IntPtr hIcon = LoadIcon(IntPtr.Zero, iconName); 
    if (hIcon == IntPtr.Zero) 
     return null; 

    return System.Windows.Interop.Imaging.CreateBitmapSourceFromHIcon(
     hIcon, Int32Rect.Empty, BitmapSizeOptions.FromEmptyOptions()); 
} 

[DllImport("user32.dll")] 
static extern IntPtr LoadIcon(IntPtr hInstance, string lpIconName);

System.Drawing.Icon myIcon = new System.Drawing.Icon(System.Drawing.SystemIcons.Question,32,32); 
label.Image = myIcon.ToBitmap();
