반환 값은 호출의 결과 IConvertible.ToUInt32 기본 형식의 메서드 value합니다.The return value is the result of invoking the IConvertible.ToUInt32 method of the underlying type of value.

provider 사용자의 내용에 대 한 문화권별 형식 변환 정보를 지정할 수 있게 value합니다.provider enables the user to specify culture-specific conversion information about the contents of value. 예를 들어 경우 value 되는 String 숫자를 나타내는 provider 해당 숫자를 나타내는 데 사용 되는 표기법에 대 한 문화권별 형식 정보를 제공할 수 있습니다.For example, if value is a String that represents a number, provider could supply culture-specific information about the notation used to represent that number.

기본 형식을 무시 provider하지만 경우에 매개 변수를 사용할 수 있습니다 value 구현 하는 사용자 정의 형식인는 IConvertible 인터페이스입니다.The base types ignore provider; however, the parameter may be used if value is a user-defined type that implements the IConvertible interface.

때문에 합니다 UInt32 데이터 형식은 부호 없는 값만 지원 합니다 ToUInt32(String, Int32) 가정 메서드 value 서명 되지 않은 이진 표현을 사용 하 여 표현 됩니다.Because the UInt32 data type supports unsigned values only, the ToUInt32(String, Int32) method assumes that value is expressed using unsigned binary representation. 즉, 모든 32 비트 숫자 값을 나타내는 데 사용 되며 및 부호 비트를 사용할 수 없는 합니다.In other words, all 32 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 UInt32 데이터 형식을 변환할는 UInt32 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 UInt32 data type is converted to a UInt32 value without the method throwing an exception. 다음 예제에서는 변환 MinValue 해당 16 진수 문자열 표현으로 변환한 다음 호출 하는 ToUInt32(String, Int32) 메서드.The following example converts MinValue to its hexadecimal string representation, and then calls the ToUInt32(String, Int32) method. 메서드는 예외를 throw 하는 대신 메시지를 표시 "-2147483648 0x80000000 변환 합니다."Instead of throwing an exception, the method displays the message, "0x80000000 converts to 2147483648."

// Create a hexadecimal value out of range of the UInt32 type.

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 UInt32 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 UInt32 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 UInt32 원래 값을 부호 있는 정수 했는지를 확인할 값입니다.When the example converts the value to a UInt32 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.
