Represents the largest possible value of UInt64. This field is constant.

This field is not CLS-compliant.  

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

public const ulong MaxValue
public static final UInt64 MaxValue
public const var MaxValue : ulong
Not applicable.

The value of this constant is 18,446,744,073,709,551,615; that is, hexadecimal 0xFFFFFFFFFFFFFFFF.

The following example uses the MinValue and MaxValue fields to verify that a Double value is within the range of the UInt64 type before it performs a type conversion. This prevents an OverflowException at run time.
