系统图标 - Windows 10 风格

Question

我有使用 SystemIcons 的自定义 MessageBox。问题是它们看起来已经过时了。请参见下图，其中包含警告/感叹号图标。我想设置与顶部 MessageBox 相同的图标。我怎样才能做到呢？

相关问题 - 如何从 dll 中提取系统图标（我已经尝试过 7-Zip 方法和 Resource Hacker，但是无法获取内部图形，但在 Visual Studio 中它显示但排列在文件树而不是缩略图中）。

我在 System32 文件夹中找到了“SecurityAndMaintenance_Alert.PNG”文件，它看起来非常相似，但是边框看起来更薄，如果可能的话，我想设置完全相同的图标。

您需要使用SHGetStockIconInfo。

\n

var sii = new NativeMethods.SHSTOCKICONINFO();\nsii.cbSize = (UInt32)Marshal.SizeOf(typeof(NativeMethods.SHSTOCKICONINFO));\nNativeMethods.SHGetStockIconInfo(NativeMethods.SHSTOCKICONID.SIID_WARNING,\n    NativeMethods.SHGSI.SHGSI_ICON,\n    ref sii);\nthis.pictureBox1.Image = Icon.FromHandle(sii.hIcon).ToBitmap();\n

您可以在这里看到所有图标。

这是 NativeMethods：
