How to set ThreadPriority property of Thread class in VB.NET

Thread Priority

Thread class's ThreadPriority property is used to sets thread's priority. The thread priority can have Normal, AboveNormal, BelowNormal, Highest, and Lowest values.

thread.Priority = ThreadPriority.Lowest

Here's a simple example without priority and its output.

 

Imports System.Threading

Module Module1

    Sub Main()

        Dim th As New Thread(AddressOf WriteY)

        th.Start()

        For i As Integer = 0 To 10

            Console.WriteLine("Hello")

        Next

    End Sub

 

    Private Sub WriteY() 

        For i As Integer = 0 To 9

            Console.WriteLine("world")

        Next

    End Sub

End Module

 

OUTPUT

 

Using With Lowest Priority

 

Imports System.Threading

Module Module1

    Sub Main()

        Dim th As New Thread(AddressOf WriteY)

        th.Priority = ThreadPriority.Lowest

        th.Start()

        For i As Integer = 0 To 10

            Console.WriteLine("Hello")

        Next

    End Sub

 

    Private Sub WriteY() 

        For i As Integer = 0 To 9

            Console.WriteLine("world")

        Next

    End Sub

End Module

 

OUTPUT

 

In the above example defines the priority, The without priority example execute the method writeY() but in the second example we defines the lowest priority it will execute main method first.
