How do I choose more than an icon in the icon file size?-CodePudding

Icon file with the icon of a single size, there are many different sizes (also may have the same size) icon to save in an icon file, for the latter if I can choose?
Read the following code is an icon file, then displayed in the picture box code, but it can't identify the target icon file is a single figure or photos, also can't choose, ask how to identify multiple icon and select one of the pieces to display,

 
Private void button1_Click (object sender, EventArgs e) 
{
DialogResult Dr=openFileDialog1. ShowDialog (this); 
If (Dr==DialogResult. OK) 
{
The string filename=openFileDialog1. Filename; 
Icon picicon=Icon. ExtractAssociatedIcon (filename); 
Image picimage=picicon. ToBitmap (); 
PictureBox1. Image=picimage; 
} 
}
