Int64.MaxValue Field in C# with Examples

The UInt64.MaxValue field in C# represents the maximum value of the 64-bit unsigned integer.

Syntax

Following is the syntax −

public const ulong MaxValue = 18446744073709551615;

Example

Let us now see an example to implement the UInt64.MaxValue field −

using System;
public class Demo {
   public static void Main(){
      ulong val1 = 879879879;
      ulong val2 = 464556565;
      Console.WriteLine("Value1 = "+val1);
      Console.WriteLine("Value2 = "+val2);
      Console.WriteLine("HashCode for value1 = "+val1.GetHashCode());
      Console.WriteLine("HashCode for value2 = "+val2.GetHashCode());
      Console.WriteLine("Are they equal? = "+(val1.Equals(val2)));
      TypeCode type1 = val1.GetTypeCode();
      TypeCode type2 = val2.GetTypeCode();
      Console.WriteLine("TypeCode for val1 = "+type1);
      Console.WriteLine("TypeCode for val2 = "+type2);
      Console.WriteLine("Maximum Value = "+ UInt64.MaxValue);
   }
}

Output

This will produce the following output −

Value1 = 879879879
Value2 = 464556565
HashCode for value1 = 879879879
HashCode for value2 = 464556565
Are they equal? = False
TypeCode for val1 = UInt64
TypeCode for val2 = UInt64
Maximum Value = 18446744073709551615

Example

Let us now see another example to implement the UInt64.MaxValue method −

using System;
public class Demo {
   public static void Main(){
      ulong[]val = {8998, 899898778, 878787878};
      ulong res;
      foreach(ulong a in val){
         if(a >= UInt64.MinValue && a <= UInt64.MaxValue){
            res = Convert.ToUInt64(a);
            Console.WriteLine("Converted: "+res);
         }
         else{
            Console.WriteLine("Not Possible");
         }
      }
   }
}

Output

This will produce the following output −

Converted: 8998
Converted: 899898778
Converted: 878787878
