Int64.ToString() Method in C#

The Int64.ToString() method in C# is used to convert the numeric value of this instance to its equivalent string representation.

Syntax

The syntax is as follows −

public override string ToString ();
public string ToString (string format);

Above, the parameter format is a numeric format string.

Example

Let us now see an example −

 Live Demo

using 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());
      Console.WriteLine("Value2 (HashCode) = "+val2.GetHashCode());
      TypeCode type1 = val1.GetTypeCode();
      TypeCode type2 = val2.GetTypeCode();
      Console.WriteLine("TypeCode for val1 = "+val1.GetTypeCode());
      Console.WriteLine("TypeCode for val2 = = "+val1.GetTypeCode());
   }
}

Output

This will produce the following output −

Value1 = 0
Value2 = 9223372036854775807
Are they equal? = False
Value1 (HashCode) = 0
Value2 (HashCode) = -2147483648
TypeCode for val1 = Int64
TypeCode for val2 = = Int64

Example

Let us now see another example −

using System;
public class Demo {
   public static void Main(){
      long val1 = 87987687;
      long val2 = 35436367;
      Console.WriteLine("Value1 = "+val1.ToString("D8"));
      Console.WriteLine("Value2 = "+val2.ToString("X"));
      Console.WriteLine("Are they equal? = "+val1.Equals(val2));
      Console.WriteLine("Value1 (HashCode) = "+val1.GetHashCode());
      Console.WriteLine("Value2 (HashCode) = "+val2.GetHashCode());
      TypeCode type1 = val1.GetTypeCode();
      TypeCode type2 = val2.GetTypeCode();
      Console.WriteLine("TypeCode for val1 = "+val1.GetTypeCode());
      Console.WriteLine("TypeCode for val2 = = "+val1.GetTypeCode());
   }
}

Output

This will produce the following output −

Value1 = 87987687
Value2 = 21CB74F
Are they equal? = False
Value1 (HashCode) = 87987687
Value2 (HashCode) = 35436367
TypeCode for val1 = Int64
TypeCode for val2 = = Int64
