Thread Lock in VB.Net

To implement thread locking, we will use the SyncLock block to resolve the problem of the critical section.

Program/Source Code:

The source code to demonstrate the thread lock is given below. The given program is compiled and executed successfully.

VB.Net code to demonstrate the example of thread lock

'Vb.Net program to demonstrate the thread lock.  

Imports System.Threading

Module Module1
    Dim obj As Object = New Object

    Public Sub MyThreadFun()
        SyncLock obj
            Thread.Sleep(100)
            Console.WriteLine(DateTime.Now)
        End SyncLock
    End Sub

    Sub Main()
        For num = 1 To 5 Step 1
            Dim T As ThreadStart = New ThreadStart(AddressOf MyThreadFun)
            Dim t1 As New Thread(T)
            t1.Start()
        Next

Explanation

In the above program, we imported the System.Threading namespace to implement multithreading in the program. After that, we created a module Module1. The Module1 contain two functions MyThreadFun() and Main().

In the MyThreadFun() function, we used the SyncLock block to lock the set of statements to avoid the problem of the critical section.

The Main() function is the entry point for the program. Here, we created threads and start them.
