In C#, UInt64 struct is used to represent 64-bit unsigned integers(also termed as the ulong data type) starting from range 0 to 18,446,744,073,709,551,615. It also provides different types of methods to compare instances of this type, convert the value of an instance to its String representation, convert the String representation of a number to an instance of this type, etc. This struct is defined under System namespace. UInt64 struct inherits the ValueType class which inherits the Object class.
Fields
Field | Description |
---|---|
MaxValue | Represents the largest possible value of UInt64. This field is constant. |
MinValue | Represents the smallest possible value of UInt64. This field is constant. |
Example:
// C# program to illustrate the // fields of UInt64 struct using System;
class GFG {
// Main Method
static public void Main()
{
// Unsigned 64-bit integer
ulong val = 18446744073709551615;
// Checking the unsigned integer
if (val.Equals(UInt64.MinValue))
{
Console.WriteLine( "Equal to MinValue!" );
}
else if (val.Equals(UInt64.MaxValue))
{
Console.WriteLine( "Equal to MaxValue!" );
}
else {
Console.WriteLine( "Not Equal!" );
}
}
} |
Output:
Equal to MaxValue!
Methods
Method | Description |
---|---|
CompareTo() | Compares the current instance to a specified object or UInt64 and returns an indication of their relative values. |
Equals() | Returns a value which shows whether the current instance is equal to a specified object or UInt64. |
GetHashCode() | Returns the hash code for the current instance. |
GetTypeCode() | Returns the TypeCode for value type UInt64. |
Parse() | Converts the string representation of a number to its 64-bit unsigned integer equivalent. |
ToString() | Converts the numeric value of the current instance to its equivalent string representation. |
TryParse() | Tries to convert the string representation of a number to its 64-bit unsigned integer equivalent. A return value indicates whether the conversion succeeded or failed. |
Example:
// C# program to illustrate how to get the // hash code of the 64-bit Unsigned integer using System;
class GFG {
// Main Method
static public void Main()
{
// UInt64 variable
ulong myval = 3654121225155;
// Get the hash code
// Using GetHashCode Method
int res = myval.GetHashCode();
Console.WriteLine( "The hash code of myval is: {0}" , res);
}
} |
Output:
The hash code of myval is: -895944559
