설명

사용 하는 ToUInt16(String) 에 전달 하는 것과 같습니다 valueUInt16.Parse(String) 메서드.Using the ToUInt16(String) method is equivalent to passing value to the UInt16.Parse(String) method. value는 현재 스레드 문화권의 서식 지정 규칙을 사용하여 해석됩니다.value is interpreted by using the formatting conventions of the current thread culture.

변환에 실패 하면 예외를 처리 하지 않으려는 경우 호출할 수 있습니다는 UInt16.TryParse 메서드 대신 합니다.If you prefer not to handle an exception if the conversion fails, you can call the UInt16.TryParse method instead. 반환 된 Boolean 변환이 성공 또는 실패 여부를 나타내는 값입니다.It returns a Boolean value that indicates whether the conversion succeeded or failed.

하는 경우 fromBase 16 이면로 지정한 숫자를 붙일 수 있습니다는 value "0x" 또는 "0x"를 사용 하 여 매개 변수입니다.If fromBase is 16, you can prefix the number specified by the value parameter with "0x" or "0X".

때문에 합니다 UInt16 데이터 형식은 부호 없는 값만 지원 합니다 ToUInt16(String, Int32) 가정 메서드 value 서명 되지 않은 이진 표현을 사용 하 여 표현 됩니다.Because the UInt16 data type supports unsigned values only, the ToUInt16(String, Int32) method assumes that value is expressed using unsigned binary representation. 즉, 모든 16 비트 숫자 값을 나타내는 데 사용 되며 및 부호 비트를 사용할 수 없는 합니다.In other words, all 16 bits are used to represent the numeric value, and a sign bit is absent. 결과적으로, 것이 코드는 부호 있는 정수 값의 범위를 벗어났습니다. 쓸 수는 UInt16 데이터 형식을 변환할는 UInt16 메서드에서 예외를 throw 하지 않고 값입니다.As a result, it is possible to write code in which a signed integer value that is out of the range of the UInt16 data type is converted to a UInt16 value without the method throwing an exception. 다음 예제에서는 변환 Int16.MinValue 해당 16 진수 문자열 표현으로 변환한 다음 호출 하는 ToUInt16(String, Int32) 메서드.The following example converts Int16.MinValue to its hexadecimal string representation, and then calls the ToUInt16(String, Int32) method. 메서드는 예외를 throw 하는 대신 메시지를 표시 "0x8000 변환 32768."Instead of throwing an exception, the method displays the message, "0x8000 converts to 32768."

이항 연산 또는 숫자 변환을 수행할 때 항상 특정 값을 해석 하는 메서드 또는 연산자가 적절 한 숫자 표현이 사용 되는 확인 하려면 개발자의 책임입니다.When performing binary operations or numeric conversions, it is always the responsibility of the developer to verify that a method or operator is using the appropriate numeric representation to interpret a particular value. 다음 예제에서는 메서드를 16 진수 문자열로 변환 하는 경우에 2의 보수 표현이 사용 하는 값을 해석으로 이진 표현의 부적절 하 게 사용 되지 않게 하는 것에 대 한 한 가지 방법은 UInt16 값입니다.The following example illustrates one technique for ensuring that the method does not inappropriately use binary representation to interpret a value that uses two's complement representation when converting a hexadecimal string to a UInt16 value. 예제 값을 나타내는지 부호 있는 또는 부호 없는 정수 값을 문자열 표현으로 변환 하는 동안 결정 합니다.The example determines whether a value represents a signed or an unsigned integer while it is converting that value to its string representation. 이 예제에서는 값을 변환 하는 경우는 UInt16 원래 값을 부호 있는 정수 했는지를 확인할 값입니다.When the example converts the value to a UInt16 value, it checks whether the original value was a signed integer. 따라서 및 해당 상위 비트가 설정 되 면 (원래 값은 음수를 나타냄) 메서드는 예외를 throw 합니다.If so, and if its high-order bit is set (which indicates that the original value was negative), the method throws an exception.

매개 변수

value
Object

IConvertible 인터페이스를 구현하는 개체An object that implements the IConvertible interface.

provider
IFormatProvider

문화권별 서식 지정 정보를 제공하는 개체입니다.An object that supplies culture-specific formatting information.

반환

value에 해당하는 16비트 부호 없는 정수이거나, valuenull이면 0입니다.A 16-bit unsigned integer that is equivalent to value, or zero if value is null.

특성

예외

value가 적절한 형식이 아닙니다.value is not in an appropriate format.

valueIConvertible 인터페이스를 구현하지 않습니다.value does not implement the IConvertible interface.

또는-or- 이 변환은 지원되지 않습니다.The conversion is not supported.

valueMinValue보다 작거나 MaxValue보다 큰 숫자를 나타냅니다.value represents a number that is less than MinValue or greater than MaxValue.

예제

다음 예제에서는 정의 HexString 클래스를 구현 하는 IConvertible 인터페이스 모두 16 비트 부호 있는 및 16 비트 부호 없는 값의 문자열 표현을 보유 하도록 설계 합니다.The following example defines a HexString class that implements the IConvertible interface and that is designed to hold the string representation of both 16-bit signed and 16-bit unsigned values. 클래스를 포함 한 Sign 16 진수 값의 부호를 나타내는 속성입니다.The class includes a Sign property that indicates the sign of its hexadecimal value.

ToUInt16(Decimal)

중요

이 API는 CLS 규격이 아닙니다.

지정된 10진수 값을 해당하는 16비트 부호 없는 정수로 변환합니다.Converts the value of the specified decimal number to an equivalent 16-bit unsigned integer.

static member ToUInt16 : decimal -> uint16
Public Shared Function ToUInt16 (value As Decimal) As UShort

매개 변수

value
Decimal

변환할 10진수입니다.The decimal number to convert.

반환

가장 가까운 16비트 부호 없는 정수로 반올림된 value입니다.value, rounded to the nearest 16-bit unsigned integer. value가 두 정수 사이의 값이면 짝수 값을 반환합니다. 예를 들어 4.5는 4로, 5.5는 6으로 변환됩니다.If value is halfway between two whole numbers, the even number is returned; that is, 4.5 is converted to 4, and 5.5 is converted to 6.
