Examples

The following example shows how to name a thread.

using namespace System;
using namespace System::Threading;
int main()
{
   
   // Check whether the thread has previously been named to
   // avoid a possible InvalidOperationException.
   if ( Thread::CurrentThread->Name == nullptr )
   {
      Thread::CurrentThread->Name =  "MainThread";
   }
   else
   {
      Console::WriteLine( "Unable to name a previously "
      "named thread." );
   }
}

using System;
using System.Threading;

class Name
{
    static void Main()
    {
        // Check whether the thread has previously been named
        // to avoid a possible InvalidOperationException.
        if(Thread.CurrentThread.Name == null)
        {
            Thread.CurrentThread.Name = "MainThread";
        }
        else
        {
            Console.WriteLine("Unable to name a previously " +
                "named thread.");
        }
    }
}

Imports System.Threading

Public Class Name

    <MTAThread> _
    Shared Sub Main()

        ' Check whether the thread has previously been named
        ' to avoid a possible InvalidOperationException.
        If Thread.CurrentThread.Name = Nothing Then
            Thread.CurrentThread.Name = "MainThread"
        Else
            Console.WriteLine("Unable to name a previously " & _
                "named thread.")
        End If

    End Sub
End Class

Remarks

This property is write-once. Because the default value of a thread's Name property is null, you can determine whether a name has already been explicitly assigned to the thread by comparing it with null.

The string assigned to the Name property can include any Unicode character.
