如何在 VB 中使用 Directory.GetFiles? [英] How to use Directory.GetFiles in VB?

问题描述

我基本上是按照一个MS的例子来做的.下面是例子.

I basically follow a MS example.The following is the example.

Imports System
Imports System.IO

Public Class Test
Public Shared Sub Main()
    Try 
        ' Only get files that begin with the letter "c." 
        Dim dirs As String() = Directory.GetFiles("c:\", "c*")
        Console.WriteLine("The number of files starting with c is {0}.", dirs.Length)
        Dim dir As String 
        For Each dir In dirs
            Console.WriteLine(dir)
        Next 
    Catch e As Exception
        Console.WriteLine("The process failed: {0}", e.ToString())
    End Try 
End Sub 
End Class

我稍微修改了一下，以便我可以将其用作文件搜索功能.但是在For Each f In Directory.GetFiles(d, FileName)"处有错误.我做错了什么?

I modify a little bit, so that I can use it as file search function. However there is an error at "For Each f In Directory.GetFiles(d, FileName)". What do I do wrong?

    Public Sub DirSearch(ByVal sDir As String, ByVal FileName As String)
    Dim d As String
    Dim f As String

    Try
        For Each d In Directory.GetDirectories(sDir)
            For Each f In Directory.GetFiles(d, FileName)
                If f = FileName Then
                    Form1.TextBox4.Text = "1"
                Else
                    Form1.TextBox4.Text = "0"
                End If
            Next
            DirSearch(d, FileName)
        Next
    Catch excpt As System.Exception
        Debug.WriteLine(excpt.Message)
    End Try
End Sub

推荐答案

我找到了，这解决了我的问题

I find this, this solve my problem

Public Sub DirSearch(ByVal sDir As String, ByVal FileName As String)
    For Each foundFile As String In My.Computer.FileSystem.GetFiles(sDir, FileIO.SearchOption.SearchAllSubDirectories, FileName)

    Next
End Sub
