BigInteger.Inequality Operator (UInt64, BigInteger)

Returns a value that indicates whether a 64-bit unsigned integer and a BigInteger value are not equal.

This API is not CLS-compliant. 

Namespace:  System.Numerics
Assembly:  System.Numerics (in System.Numerics.dll)
public static bool operator !=(
	ulong left,
	BigInteger right
)

Parameters

left
Type: System.UInt64

The first value to compare.

right
Type: System.Numerics.BigInteger

The second value to compare.

Return Value

Type: System.Boolean
true if left and right are not equal; otherwise, false.

The Inequality method defines the operation of the inequality operator 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...
}

Languages that do not support custom operators can test for inequality by using one of the following techniques:

.NET Framework

Supported in: 4.5.1, 4.5, 4

.NET Framework Client Profile

Supported in: 4

Portable Class Library

Supported in: Portable Class Library

.NET for Windows Store apps

Supported in: Windows 8

.NET for Windows Phone apps

Supported in: Windows Phone 8.1

Windows Phone 8.1, Windows Phone 8, Windows 8.1, Windows Server 2012 R2, Windows 8, Windows Server 2012, Windows 7, Windows Vista SP2, Windows Server 2008 (Server Core Role not supported), Windows Server 2008 R2 (Server Core Role supported with SP1 or later; Itanium not supported)

The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
