Question

在C#里，怎么获取.exe文件的ICO

Answer 1

看看下面这个例子，用WIN API来做
using System;
using System.Runtime.InteropServices;
using System.Drawing;

namespace WindowsAppTmp
{
public class ExtractIcon
{
[DllImport("Shell32.dll")]
private static extern int SHGetFileInfo
(
string pszPath,
uint dwFileAttributes,
out SHFILEINFO psfi,
uint cbfileInfo,
SHGFI uFlags
);

[StructLayout(LayoutKind.Sequential)]
private struct SHFILEINFO
{
public SHFILEINFO(bool b)
{
hIcon=IntPtr.Zero;iIcon=0;dwAttributes=0;szDisplayName="";szTypeName="";
}
public IntPtr hIcon;
public int iIcon;
public uint dwAttributes;
[MarshalAs(UnmanagedType.LPStr, SizeConst=260)]
public string szDisplayName;
[MarshalAs(UnmanagedType.LPStr, SizeConst=80)]
public string szTypeName;
};

private ExtractIcon()
{
}

private enum SHGFI
{
SmallIcon = 0x00000001,
LargeIcon = 0x00000000,
Icon = 0x00000100,
DisplayName = 0x00000200,
Typename = 0x00000400,
SysIconIndex = 0x00004000,
UseFileAttributes = 0x00000010
}

public static Icon GetIcon(string strPath, bool bSmall)
{
SHFILEINFO info = new SHFILEINFO(true);
int cbFileInfo = Marshal.SizeOf(info);
SHGFI flags;
if (bSmall)
flags = SHGFI.Icon|SHGFI.SmallIcon|SHGFI.UseFileAttributes;
else
flags = SHGFI.Icon|SHGFI.LargeIcon|SHGFI.UseFileAttributes;

SHGetFileInfo(strPath, 256, out info,(uint)cbFileInfo, flags);
return Icon.FromHandle(info.hIcon);
}
}
}

Answer 2

在C#中可以使用 Icon icon = System.Drawing.Icon.ExtractAssociatedIcon(fileFullName) 来得到指定文件图标。
2005有这个方法~~~
