要用到命名空间：using System.IO; public Icon[] myicon=new Icon[1000]; public int currentIndex=0; [System.Runtime.InteropServices.DllImport("shell32.dll")] private static extern int ExtractIconEx(string lpszFile, int niconIndex, ref IntPtr phiconLarge, ref IntPtr phiconSmall, int nIcons);//打开exe文件 private void button1_Click(object sender, EventArgs e) { if (openFileDialog1.ShowDialog() == DialogResult.OK) { this.Refresh(); IntPtr Large, Small; int i, nIcons; Large = (IntPtr)0; Small = (IntPtr)0; nIcons = ExtractIconEx(openFileDialog1.FileName, -1, ref Large, ref Small, 1); Graphics g = this.CreateGraphics(); for (i = 0; i < nIcons; i++) { ExtractIconEx(openFileDialog1.FileName, i, ref Large, ref Small, 1); myicon[currentIndex] = Icon.FromHandle(Large); g.DrawIcon(myicon[currentIndex], (i / 3) * 40, (i % 3) * 40); currentIndex++; } } }//保存icon图标 private void button2_Click(object sender, EventArgs e) { FileStream fs; for (int j = 0; j < currentIndex; j++) { fs = new FileStream("c://"+j.ToString()+".ico",FileMode.Create,FileAccess .ReadWrite); myicon[j].Save(fs); fs.Close(); } MessageBox.Show ("保存成功！"); }
