My.User.Name Property 

Gets the name of the current user.

' Usage
Dim value As String = My.User.Name
' Declaration
Public ReadOnly Property Name As String

Return Value

String. The name of the current user.

Remarks

You can use the My.User object to get information about the current user.

The principal that authenticates the user also controls the format of the user name. By default, an application uses Windows authentication, and the user name has the format DOMAIN\USERNAME. A custom implementation of the principal does not necessarily use the same format.

Tasks

The following table lists examples of tasks involving the My.User.Name property.

Example

This example checks if the application is using Windows or custom authentication, and uses that information to parse the My.User.Name property.

Function GetUserName() As String
    If TypeOf My.User.CurrentPrincipal Is _
    Security.Principal.WindowsPrincipal Then
        ' The application is using Windows authentication.
        ' The name format is DOMAIN\USERNAME.
        Dim parts() As String = Split(My.User.Name, "\")
        Dim username As String = parts(1)
        Return username
    Else
        ' The application is using custom authentication.
        Return My.User.Name
    End If
End Function
