NullReferenceException occurs when you try to to access member fields, or function types that points to null.Here is an example −Example Live Demousing System; class Demo {    static void Main() {       string str = null;       if (str.Length > 0) {     ... Read More

It copies the bytes from one byte array to another byte array.Example Live Demousing System; class Demo {    static void Main() {       // byte arrays       byte[] b1 = new byte[] {55, 66, 77, 88, 99};       byte[] b2 = new byte[8];   ... Read More

Create a string array −string[] str = new string[] {    "Videos",    "Tutorials",    "Tools",    "InterviewQA" };Loop until the length of the array −for (int i = 0; i < str.Length; i++) {    string res = str[i];    Console.WriteLine(res); }Here is the complete code −Example Live Demousing System; ...

Hashtable is slower than Dictionary. For strongly-typed collections, the Dictionary collection is faster.HashtableHashtable class represents a collection of key-and-value pairs that are organized based on the hash code of the key. It uses the key to access the elements in the collection.Let us see an example −Example Live Demousing System; using ... Read More
