This is a sample from a console application implementation.
这是来自控制台应用程序实现的示例。
using System;
using System.Drawing; //For Icon
using System.Reflection; //For Assembly
namespace ConsoleApplication
{
class Program
{
static void Main(string[] args)
{
try
{
//Gets the icon associated with the currently executing assembly
//(or pass a different file path and name for a different executable)
Icon appIcon = Icon.ExtractAssociatedIcon(Assembly.GetExecutingAssembly().Location);
}
catch(ArgumentException ae)
{
//handle
}
}
}
}

Use the ExtractIconEx(and here) p/invoke. You can extract small and large icons from any dll or exe. Shell32.dll itself has over 200 icons that are quite useful for a standard Windows application. You just have to first figure out what the index is for the icon(s) you want.

Edit: I did quick SO search and found this. The index 0 icon is the application icon.
编辑：我进行了快速搜索并找到了这个。索引 0 图标是应用程序图标。
