如何通过驱动器号获取VB.NET中的驱动器类型。 [英] How to get the drive type in VB.NET by drive letter.

问题描述

我正在制作一个程序，用硬盘驱动器，本地磁盘，CD驱动器，sdhd，系统驱动器（c :)等驱动器号显示用户输入驱动器的类型。



我尝试过：

 Public Class Form1 
 
 Private Sub Button1_Click（ByVal sender As System.Object，ByVal e As System.EventArgs）Handles Button1.Click 
 dfunton（TextBox1.Text）
 End Sub 
 
 Private Sub dfunton（ ByVal p1 As Object）
'获取驱动器类型的代码
 Label1.Text =drivetype
 End Sub 
 
 End Class 

解决方案

查看 DriveInfo类（System.IO） [ ^ ] - 它返回您需要的信息。

 Public Class Fo rm1 
 
 Private Sub Button1_Click（ByVal sender As System.Object，ByVal e As System.EventArgs）Handles Button1.Click 
 dfunton（TextBox1.Text）
 End Sub 
 
 Private Sub GetDrivetype（ByVal drive As String）
尝试
 Dim Drive_Info As System.IO.DriveInfo 
 Drive_Info = New System.IO.DriveInfo（drive）
 Label1.Text = Drive_Info.DriveType.ToString 
 Catch ex As Exception 
 MsgBox（ex.Data）
 End Try 
 End Sub 
 
 End Class 

I am making a program that shows the type of the user inputted drive by drive letter like pen drive , local disk , cd drive, sdhd, system drive (c:).

What I have tried:

Public Class Form1

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        dfunton(TextBox1.Text)
    End Sub

    Private Sub dfunton(ByVal p1 As Object)
        'code for getting drive type
        Label1.Text = "drivetype"
    End Sub

End Class

解决方案

Look at the DriveInfo Class (System.IO)[^] - it returns the info you need.

Public Class Form1

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        dfunton(TextBox1.Text)
    End Sub

    Private Sub GetDrivetype(ByVal drive As String)
        Try
            Dim Drive_Info As System.IO.DriveInfo
            Drive_Info = New System.IO.DriveInfo(drive)
            Label1.Text = Drive_Info.DriveType.ToString
        Catch ex As Exception
            MsgBox(ex.Data)
        End Try
    End Sub

End Class
