Get And Display Hard Disk Serial Number In VB.NET

Submitted by donbermoy on Thursday, August 6, 2015 - 13:10.

This tutorial is all about getting and displaying the hard disk serial number for a complete disk but not in just a single drive using vb.net. Now, let's start this tutorial! 1. Let's start with creating a Windows Form Application for this tutorial by following the following steps in Microsoft Visual Studio: Go to File, click New Project, and choose Windows Application. 2. Next, add only one textbox named TextBox1 in your Form. 3. Now, lets do the coding. First, we will import the following libraries below to access the hard disk information.

Imports System.Collections
Imports System.Management

Then, we will declare a variable for getting the Thread attribute.

Dim WindowsApplication1 As System.STAThreadAttribute()

Also declare variables for ArrayList, ManagementObjectSearcher, and ManagementObject inside the Form_Load.

        Dim hdCollection As New ArrayList()
        Dim searcher As New ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive")
        Dim wmi_HD As New ManagementObject()

Then, we will get the model and the type of the hard drive by using the for each loop with our searcher variable created above.

        For Each wmi_HD In searcher.Get
 
            Dim hd As New Class1.HardDrive()
 
            hd.Model = wmi_HD("Model").ToString()
            hd.Type = wmi_HD("InterfaceType").ToString()
            hdCollection.Add(hd)
        Next
 
 Dim searcher1 As New ManagementObjectSearcher("SELECT * FROM Win32_PhysicalMedia")
 
 
        Dim i As Integer = 0
        For Each wmi_HD In searcher1.Get()
 
            '// get the hard drive from collection
            '// using index
 
            Dim hd As Class1.HardDrive
            hd = hdCollection(i)
 
 
            '// get the hardware serial no.
            If wmi_HD("SerialNumber") = "" Then
                hd.serialNo = "None"
            Else
                hd.serialNo = wmi_HD("SerialNumber").ToString()
                i += 1
            End If
        Next

Then display all the serial numbers on the textbox by the hdCollection.

        Dim hd1 As Class1.HardDrive
        Dim ii As Integer = 0
 
        For Each hd1 In hdCollection
            ii += 1
        
            TextBox1.Text = TextBox1.Text + "Serial No: " + hd1.serialNo + Chr(13) + Chr(10) + Chr(13) + Chr(10)
        Next
