在.Net(C#或VB:无关)中,给定文件路径字符串,FileInfo结构或FileSystemInfo结构用于实际的现有文件,我如何确定外壳程序(浏览器)为此使用的图标文件?
我目前不打算将其用于任何用途,但是当看到这个问题时,我对如何做到这一点感到好奇,并且我认为将其存档在SO上将很有用。
Imports System.Drawing Module Module1 Sub Main() Dim filePath As String = "C:\myfile.exe" Dim TheIcon As Icon = IconFromFilePath(filePath) If TheIcon IsNot Nothing Then ''#Save it to disk, or do whatever you want with it. Using stream As New System.IO.FileStream("c:\myfile.ico", IO.FileMode.CreateNew) TheIcon.Save(stream) End Using End If End Sub Public Function IconFromFilePath(filePath As String) As Icon Dim result As Icon = Nothing Try result = Icon.ExtractAssociatedIcon(filePath) Catch ''# swallow and return nothing. You could supply a default Icon here as well End Try Return result End Function End Module
