Returns a value that indicates whether an unsigned long integer value and a BigInteger value are equal.
public:
static bool operator ==(System::UInt64 left, System::Numerics::BigInteger right);
[System.CLSCompliant(false)]
public static bool operator == (ulong left, System.Numerics.BigInteger right);
[<System.CLSCompliant(false)>]
static member ( = ) : uint64 * System.Numerics.BigInteger -> bool
Public Shared Operator == (left As ULong, right As BigInteger) As Boolean
Parameters
- left
- UInt64
The first value to compare.
- right
- BigInteger
The second value to compare.
Returns
true
if the left
and right
parameters have the same value; otherwise, false
.

Remarks
The Equality(UInt64, BigInteger) method defines the equality comparison operation for BigInteger values. It enables code such as the following:
BigInteger bigNumber = BigInteger.Pow(2, 63) - BigInteger.One;
ulong uNumber = Int64.MaxValue & 0x7FFFFFFFFFFFFFFF;
if (uNumber == bigNumber)
{
// Do something...
}
let bigNumber = BigInteger.Pow(2, 63) - BigInteger.One
let uNumber = uint64 Int64.MaxValue &&& 0x7FFFFFFFFFFFFFFFuL
if bigint uNumber = bigNumber then
// Do something...
Dim bigNumber As BigInteger = BigInteger.Pow(2, 63) - BigInteger.One
Dim uNumber As ULong = CULng(Int64.MaxValue And CULng(&h7FFFFFFFFFFFFFFF))
If uNumber = bigNumber Then
' Do something...
End If
Languages that do not support custom operators can call the BigInteger.Equals(UInt64) instance method instead.

Remarks
The Equality(BigInteger, BigInteger) method defines the operation of the equality operator for BigInteger values. It enables code such as the following:
BigInteger number1 = 945834723;
BigInteger number2 = 345145625;
BigInteger number3 = 945834723;
Console.WriteLine(number1 == number2); // Displays False
Console.WriteLine(number1 == number3); // Displays True
let number1 = 945834723I
let number2 = 345145625I
let number3 = 945834723I
printfn $"{number1 = number2}" // Displays False
printfn $"{number1 = number3}" // Displays True
Dim number1 As BigInteger = 945834723
Dim number2 As BigInteger = 345145625
Dim number3 As BigInteger = 945834723
Console.WriteLine(number1 = number2) ' Displays False
Console.WriteLine(number1 = number3) ' Displays True
Languages that do not support custom operators can call the BigInteger.Equals(BigInteger) instance method instead.
The equivalent method for this operator is BigInteger.Equals(BigInteger).

If left
is a Byte, Int16, Int32, SByte, UInt16, or UInt32 value, it is implicitly converted to an Int64 value when the operation is performed.
The equivalent method for this operator is BigInteger.Equals(Int64).
