# UInt64.MaxValueUInt64.MaxValueUInt64.MaxValueUInt64.MaxValue Field

## 정의

UInt64의 최대값을 나타냅니다.Represents the largest possible value of UInt64. 이 필드는 상수입니다.This field is constant.

``public: System::UInt64 MaxValue = 18446744073709551615;``
``public const ulong MaxValue = 18446744073709551615;``
``val mutable MaxValue : uint64``
``Public Const MaxValue As ULong  = 18446744073709551615``

## 예제

다음 예제에서는 합니다 MinValueMaxValue 되었는지 확인 하는 필드를 Double 값이 범위 내에 UInt64 형식 변환을 수행 하기 전에 입력 합니다.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. 그러면는 OverflowException 런타임 시.This prevents an OverflowException at run time.

``````double decimalValue = -1.5;
ulong integerValue;

// Discard fractional portion of Double value
double decimalInteger = Math.Floor(decimalValue);

if (decimalInteger <= ulong.MaxValue &&
decimalInteger >= ulong.MinValue)
{
integerValue = (ulong) decimalValue;
Console.WriteLine("Converted {0} to {1}.", decimalValue, integerValue);
}
else
{
ulong rangeLimit;
string relationship;

if (decimalInteger > ulong.MaxValue)
{
rangeLimit = ulong.MaxValue;
relationship = "greater";
}
else
{
rangeLimit = ulong.MinValue;
relationship = "less";
}

Console.WriteLine("Conversion failure: {0} is {1} than {2}.",
decimalInteger,
relationship,
rangeLimit);
}
``````
``````Dim decimalValue As Double = -1.5
