    Dim ComputerName As String
    ComputerName = System.Net.Dns.GetHostName
    Return ComputerName
End Function

this code working, but i remember that there is faster way.

what is the fast way to get the computer name?

回答1:

you can just use without function:

System.Net.Dns.GetHostName

or:

Environment.MachineName

This is not that good the previous anwser,but if you love to work with forms:

Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load

    Me.Text = System.Windows.Forms.SystemInformation.ComputerName

End Sub

System.Windows.Forms.SystemInformation gives a lot of nice informations.

-> UserDomainName

-> UserName

There is a nice static property that should work anywhere in your program and in both VB.NET and C#:

System.Environment.MachineName

Because System namespace is imported automatically by default, it should be enough to refer to it simply by typing Environment.MachineName.

For unknown reason My.Computer.Name is not working for many people (including me) despite it is often being mentioned as a correct way to get the current hostname. So you don't need to bother trying to make it work.

An other way to get the computer name not mentioned in the previous responses:

My.Computer.Name

Edit

Works for VB.NET only, not C#

回答5:

For WPF application:

1. Place a Button and TextBlock on the MainWindow.xaml form
2. Create a name for the button and textblock. Example: TextBlock1, Button1

Code Example #1

Private Sub load(sender As Object, e As EventArgs)Handles MyBase.Loaded

TextBlock1.Text = Environment.MachineName 

End Sub

Code Example #2

Private Sub Button_Click_1(sender As Object, e As RoutedEventArgs) Handles Button1.Click

TextBlock1.Text = Environment.MachineName 

MyBase.Title = "Hello " + Environment.MachineName 

End Sub

Hope this gives you a more understanding on how to show the users Computer Name.

I stopped using Windows Form Applications because they are way to laggy. Now I'm using WPF Applications mainly because its a lot smoother and it has more customizations and coding WPF applications are a lot similar to Windows Form Applications.
