The Double.IsNegativeInfinity() method in C# is used to return a value indicating whether the specified number evaluates to negative infinity.SyntaxThe syntax is as follows −public static bool IsNegativeInfinity (double val);Above, val is a double-precision floating-point number.ExampleLet us now see an example − Live Demousing System; public class Demo {    public static void Main(){       double d = 0.0/0;       Console.WriteLine("Double Value = "+d);       Console.WriteLine("HashCode of Double Value = "+d.GetHashCode());       TypeCode type = d.GetTypeCode();       Console.WriteLine("TypeCode of Double Value = "+type);       Console.WriteLine("Positive Infinity? = "+Double.IsInfinity(d));   ...

The StringBuilder.EnsureCapacity() method in C# is used to ensure that the capacity of this instance of StringBuilder is at least the specified value.SyntaxThe syntax is as follows −public int EnsureCapacity (int capacity);Above, the parameter capacity is the minimum capacity to ensure.ExampleLet us now see an example − Live Demousing System; using System.Text; public class Demo{    public static void Main(){       StringBuilder strBuilder = new StringBuilder("jhbjhb");       Console.WriteLine("String = "+strBuilder);       Console.WriteLine("StringBuilder capacity= "+strBuilder.Capacity);       strBuilder.EnsureCapacity(20);       Console.WriteLine("StringBuilder capacity= "+strBuilder.Capacity);       char[] arr = new char[5] {'a', 'b', 'c', ...

The Int64.ToString() method in C# is used to convert the numeric value of this instance to its equivalent string representation.SyntaxThe syntax is as follows −public override string ToString (); public string ToString (string format);Above, the parameter format is a numeric format string.ExampleLet us now see an example − Live Demousing System; public class Demo {    public static void Main(){       long val1 = 0;       long val2 = Int64.MaxValue;       Console.WriteLine("Value1 = "+val1.ToString());       Console.WriteLine("Value2 = "+val2.ToString());       Console.WriteLine("Are they equal? = "+val1.Equals(val2));       Console.WriteLine("Value1 (HashCode) = "+val1.GetHashCode()); ...

The Random.NextBytes() method in C# is used to fill the elements of a specified array of bytes with random numbers.SyntaxThe syntax is as follows −public virtual void NextBytes (byte[] buffer);Above the buffer is the array of bytes.ExampleLet us now see an example − Live Demousing System; public class Demo {    public static void Main(){       Random r = new Random();       Random r2 = new Random();       Random r3 = new Random();       Byte[] arr = new Byte[5];       r3.NextBytes(arr);       Console.WriteLine("Random numbers.....");       for (int i = 1; i

The Queue.GetEnumerator() method in C# is used to return an enumerator that iterates through the Queue.SyntaxThe syntax is as follows:public virtual System.Collections.IEnumerator GetEnumerator ();ExampleLet us now see an example − Live Demousing System; using System.Collections; public class Demo {    public static void Main(){       Queue queue = new Queue();       queue.Enqueue(100);       queue.Enqueue(200);       queue.Enqueue(300);       queue.Enqueue(400);       Console.WriteLine("Queue1...");       IEnumerator demoEnum = queue.GetEnumerator();       while (demoEnum.MoveNext()){          Console.WriteLine(demoEnum.Current);       }       Queue queue2 = new Queue(); ...

The Single.IsInfinity() method in C# is used to return a value indicating whether the specified number evaluates to negative or positive infinity.SyntaxThe syntax is as follows −public static bool IsInfinity (float val);Above, val is a single-precision floating-point number.ExampleLet us now see an example − Live Demousing System; public class Demo {    public static void Main(){       float f1 = 19.3f;       float f2 = Single.MaxValue;       Console.WriteLine("Value1 = "+f1);       Console.WriteLine("Hashcode for Value1 = "+f1.GetHashCode());       Console.WriteLine("TypeCode for Value1 = "+f1.GetTypeCode());       Console.WriteLine("Is Value1 value is positive or ...

The Int 64 struct represents a 64-bit signed integer. It is an immutable value type representing signed integers with values: negative 9, 223, 372, 036, 854, 775, 808 through positive 9, 223, 372, 036, 854, 775, 807.Following are the fields of Int 64 −FieldDescriptionMaxValueRepresents the largest possible value of an Int64. This field is constant.MinValueRepresents the smallest possible value of an Int64. This field is constant.Following are some of the methods −FieldDescriptionCompareTo(Int64)Compares this instance to a specified 64-bit signed integer and returns an indication of their relative values.CompareTo(Object)Compares this instance to a specified object and returns an indication of their ...
