Naming a thread and fetching name of current thread in C#

Last Updated : 24 Jan, 2019

A thread is a light-weight process within a process. In C#, a user is allowed to assign a name to the thread and also find the name of the current working thread by using the Thread.Name property of the Thread class.

Syntax :

public string Name { get; set; }

Here, the string contains the name of the thread or null if no name was assigned or set.

Important Points:

The by default value of the Name property is null.
The string given to the name property can include any Unicode Character.
The name property of Thread class is write-once.
If a set operation was requested, but the Name property has already set, then it will give InvalidOperationException.

Example 1:

   // C# program to illustrate the  
// concept of assigning names  
// to the thread and fetching 
// name of the current working thread 
using System; 
using System.Threading; 
  
class Geek { 
  
    // Method of Geek class 
    public void value() 
    { 
        // Fetching the name of  
        // the current thread 
        // Using Name property 
        Thread thr = Thread.CurrentThread; 
        Console.WriteLine("The name of the current "+ 
                           "thread is: " + thr.Name); 
    } 
} 
  
// Driver class 
public class GFG { 
  
    // Main Method 
    static public void Main() 
    { 
  
        // Creating object of Geek class 
        Geek obj = new Geek(); 
  
        // Creating and initializing threads 
        Thread thr1 = new Thread(obj.value); 
        Thread thr2 = new Thread(obj.value); 
        Thread thr3 = new Thread(obj.value); 
        Thread thr4 = new Thread(obj.value); 
  
        // Assigning the names of the threads 
        // Using Name property 
        thr1.Name = "Geeks1"; 
        thr2.Name = "Geeks2"; 
        thr3.Name = "Geeks3"; 
        thr4.Name = "Geeks4"; 
  
        thr1.Start(); 
        thr2.Start(); 
        thr3.Start(); 
        thr4.Start(); 
    } 
} 
 
  

Output:

  The name of the current thread is: Geeks2  The name of the current thread is: Geeks3  The name of the current thread is: Geeks4  The name of the current thread is: Geeks1

Example 2:

   // C# program to illustrate the  
// concept of giving a name to thread 
using System; 
using System.Threading; 
  
class Name { 
    static void Main() 
    { 
  
        // Check whether the thread 
        // has already been named 
        // to avoid InvalidOperationException 
        if (Thread.CurrentThread.Name == null) { 
  
            Thread.CurrentThread.Name = "MyThread"; 
            Console.WriteLine("The name of the thread is MyThread"); 
        } 
        else { 
            Console.WriteLine("Unable to name the given thread"); 
        } 
    } 
}
