예시
다음 코드 예제 에 서 는 스 레 드 의 현재 지역성, 지정 지역성 및 모든 표준 디지털 형식 을 사용 하여 하나의 정형 수치 와 부동 소수점 수 치 를 포맷 합 니 다.이 코드 예제 에 서 는 두 가지 특정한 수치 유형 을 사용 하지만 모든 기본 수치 유형 (Byte, SByte, Int 16, Int 32, Int 64, UInt 16, UInt 64, Decimal, Single 화해시키다 Double) 비슷 한 결과 가 나 올 것 이다.

// This code example demonstrates the ToString(String) and 

// ToString(String, IFormatProvider) methods for integral and

// floating-point numbers, in conjunction with the standard 

// numeric format specifiers.

// This code example uses the System.Int32 integral type and 

// the System.Double floating-point type, but would yield 

// similar results for any of the numeric types. The integral 

// numeric types are System.Byte, SByte, Int16, Int32, Int64, 

// UInt16, UInt32, and UInt64. The floating-point numeric types 

// are Decimal, Single, and Double.
