Public Shared Function GetDomainID () As Integer

A 32-bit signed integer uniquely identifying the application domain.

The following code example shows how to retrieve the name and ID of the AppDomain in which the thread is running.

using System;
using System.Threading;

class Test
{
    static void Main()
    {
        Thread newThread = new Thread(new ThreadStart(ThreadMethod));
        newThread.Start();
    }

    static void ThreadMethod()
    {
        Console.WriteLine(
            "Thread {0} started in {1} with AppDomainID = {2}.",
            AppDomain.GetCurrentThreadId().ToString(), 
            Thread.GetDomain().FriendlyName, 
            Thread.GetDomainID().ToString());
    }
}

    printfn $"Thread {AppDomain.GetCurrentThreadId()} started in {Thread.GetDomain().FriendlyName} with AppDomainID = {Thread.GetDomainID()}."
