习惯于通过shell文件图标 [英] Get File Icon used by Shell

问题描述

在。NET（C＃或VB：不在乎），给定一个文件路径字符串，FileInfo的结构或FileSystemInfo结构为一个真正存在的文件，我怎么能确定由外壳的图标（S）（探险家），该文件？

我并不是目前正计划使用任何东西，但是当在看<一我开始好奇怎么办呢href="http://stackoverflow.com/questions/462232/what-is-the-best-vb-net-control-standard-custom-for-displaying-list-of-files">this问题，我认为这将是在这里存档的那么有用。

解决方案

 进口System.Drawing中
模块模块1

    副主（）
        昏暗文件路径作为字符串=C：\ myfile.exe
        昏暗TheIcon为图标= IconFromFilePath（文件路径）

        如果TheIcon状态并没有任何然后
            ''#Save到磁盘，或做任何你想做的事情。
            使用流作为新System.IO.FileStream（C：\ myfile.ico，IO.FileMode.CreateNew）
                TheIcon.Save（流）
            结束使用
        结束如果
    结束小组

    公共功能IconFromFilePath（文件路径作为字符串）作为图标
        昏暗的结果为图标=无
        尝试
            结果= Icon.ExtractAssociatedIcon（文件路径）
        抓''＃燕子和返回任何结果。你可以提供一个默认的图标在这里也
        结束尝试
        返回结果

In .Net (C# or VB: don't care), given a file path string, FileInfo struct, or FileSystemInfo struct for a real existing file, how can I determine the icon(s) used by the shell (explorer) for that file?

I'm not currently planning to use this for anything, but I became curious about how to do it when looking at this question and I thought it would be useful to have archived here on SO.

解决方案

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
