To pause a thread in C#, use the sleep() method.You need to set the milliseconds for which you want the thread to pause, for example, for 5 seconds, use −Thread.Sleep(5000);ExampleLet us see how to loop through and set the sleep method to pause the thread.Live Demousing System; using System.Threading; namespace Sample { class Demo { static void Main(string[] args) { for (int i = 0; i < 10; i++) { Console.WriteLine("Sleep for 1 second!"); Thread.Sleep(1000); } ...

To work with threads, add the following namespace in your code −using System.Threading;Firstly, you need to create a new thread in C# −Thread thread = new Thread(threadDemo);Above, threadDemo is our thread function.Now pass a parameter to the thread −thread.Start(str);The parameter set above is −String str = "Hello World!";ExampleLet us see the complete code to pass a parameter to a thread in C#.Live Demousing System; using System.Threading; namespace Sample { class Demo { static void Main(string[] args) { String str = "Hello World!"; // new thread ...

The sleep method of the thread is used to pause the thread for a specific period.If you want to set sleep for some seconds, then use it like the following code snippet −int sleepfor = 2000; Thread.Sleep(sleepfor);ExampleYou can try to run the following code to implement the sleep method of the thread.Live Demousing System; using System.Threading; namespace MyApplication { class ThreadCreationProgram { public static void CallToChildThread() { Console.WriteLine("Child thread starts"); int sleepfor = 2000; Console.WriteLine("Child Thread Paused for {0} seconds", sleepfor / 1000); ...

Firstly find the hostname using the Dns.GetHostName() method in C# −String hostName = string.Empty; hostName = Dns.GetHostName(); Console.WriteLine("Hostname: "+hostName);Now, use the IPHostEntry.AddressList Property to get IP Address −IPHostEntry myIP = Dns.GetHostEntry(hostName); IPAddress[] address = myIP.AddressList;ExampleTry the following code to display IP address −using System; using System.Net; class Program { static void Main() { String hostName = string.Empty; hostName = Dns.GetHostName(); IPHostEntry myIP = Dns.GetHostEntry(hostName); IPAddress[] address = myIP.AddressList; for (int i = 0; i < address.Length; i++) { Console.WriteLine("IP Address {1} : ",address[i].ToString()); } Console.ReadLine(); } }

Firstly, set the original array −int[] arr = { 15, 16, 17, 18 }; // Original Array Console.WriteLine("Original Array= "); foreach (int i in arr) { Console.WriteLine(i); }Now, use the Array.reverse() method to reverse the array −Array.Reverse(arr);ExampleThe following is the complete code to reverse an array in C#Live Demousing System; class Demo { static void Main() { int[] arr = { 15, 16, 17, 18 }; // Original Array Console.WriteLine("Original Array= "); foreach (int i in arr) { Console.WriteLine(i); } // Reverse Array Array.Reverse(arr); Console.WriteLine("Reversed Array= "); foreach (int j in arr) { Console.WriteLine(j); } Console.ReadLine(); } }OutputOriginal Array= 15 16 17 18 Reversed Array= 18 17 16 15

Our sample string is −myStr = "Tom";To reverse the string, firstly find the length of the string −// find string length int len; len = myStr.Length - 1;Now, use a while loop until the length is greater than 0 −while (len >= 0) { rev = rev + myStr[len]; len--; }ExampleYou can try to run the following code to reverse a string in C#.Live Demousing System; class Demo { static void Main() { string myStr, rev; myStr = "Tom"; rev =""; Console.WriteLine("String is {0}", myStr); ...
