설명

이 메서드는 .NET의 복합 서식 지정 기능 을 사용 하 여 개체의 값을 해당 텍스트 표현으로 변환 하 고 문자열에 해당 표현을 포함 합니다.This method uses the composite formatting feature of .NET to convert the value of an object to its text representation and embed that representation in a string. 결과 문자열은 출력 스트림에 기록 됩니다.The resulting string is written to the output stream.

format매개 변수는이 메서드의 매개 변수 목록에 있는 개체에 해당 하는 0 개 이상의 인덱싱된 자리 표시자 (서식 항목 이라고 함)와 결합 된 0 개 이상의 텍스트 실행으로 구성 됩니다.The format parameter consists of zero or more runs of text intermixed with zero or more indexed placeholders, called format items, that correspond to an object in the parameter list of this method. 서식 지정 프로세스에서는 각 형식 항목을 해당 개체의 값에 대 한 텍스트 표현으로 바꿉니다.The formatting process replaces each format item with the text representation of the value of the corresponding object.

서식 항목의 구문은 { , : } 필수 인덱스, 서식 있는 텍스트의 선택적 길이와 맞춤 및 해당 개체의 형식을 지정 하는 방법을 제어 하는 서식 지정자 문자의 선택적 문자열을 지정 하는 index [alignment] [formatString]입니다.The syntax of a format item is {index[,alignment][:formatString]}, which specifies a mandatory index, the optional length and alignment of the formatted text, and an optional string of format specifier characters that govern how the value of the corresponding object is formatted.

.NET에서는 다음 서식 지정 항목에 자세히 설명 되어 있는 광범위 한 서식 지정을 지원 합니다..NET provides extensive formatting support, which is described in greater detail in the following formatting topics.

   // Assign 10 random integers to an array.
   Random^ rnd = gcnew Random();
   array<Int32>^ numbers = gcnew array<Int32>(10);

Public Shared Sub WriteLine (value As Object)

매개 변수

value: Object

작성할 값입니다.The value to write.

예외

IOException

I/O 오류가 발생했습니다.An I/O error occurred.

예제

다음 예제에서는 메서드를 사용 하 여 WriteLine(Object) 개체 배열의 각 값을 콘솔에 표시 합니다.The following example uses the WriteLine(Object) method to display each value in an object array to the console.

using namespace System;

void main()
{
   array<Object^>^ values = { true, 12.632, 17908, "stringValue",
                              'a', (Decimal) 16907.32 };
   for each (Object^ value in values)
      Console::WriteLine(value);
}
// The example displays the following output:
//    True
//    12.632
//    17908
//    stringValue
//    a
//    16907.32

Object[] values = { true, 12.632, 17908, "stringValue",
                           'a', 16907.32m };
foreach (var value in values)
   Console.WriteLine(value);

// The example displays the following output:
//    True
//    12.632
//    17908
//    stringValue
//    a
//    16907.32

Module Example
   Public Sub Main()
      Dim values() As Object = { True, 12.632, 17908, "stringValue",
                                 "a"c, 16907.32d }
      For Each value In values
         Console.WriteLine(value)
      Next                           
   End Sub
End Module
' The example displays the following output:
'    True
'    12.632
'    17908
'    stringValue
'    a
'    16907.32

설명

value가 null이면 줄 종결자만 씁니다.If value is null, only the line terminator is written. 그렇지 않으면 ToString 의 메서드를 value 호출 하 여 문자열 표현을 생성 하 고 결과 문자열을 표준 출력 스트림에 씁니다.Otherwise, the ToString method of value is called to produce its string representation, and the resulting string is written to the standard output stream.

중요

이 API는 CLS 규격이 아닙니다.

지정한 형식 정보를 사용하여 뒤에 현재 줄 종결자가 오는, 지정한 개체 및 가변 길이 매개 변수 목록의 텍스트 표현을 표준 출력 스트림에 씁니다.Writes the text representation of the specified objects and variable-length parameter list, followed by the current line terminator, to the standard output stream using the specified format information.

public:
 static void WriteLine(System::String ^ format, System::Object ^ arg0, System::Object ^ arg1, System::Object ^ arg2, System::Object ^ arg3);

[System.CLSCompliant(false)]
public static void WriteLine (string format, object arg0, object arg1, object arg2, object arg3);

[<System.CLSCompliant(false)>]
static member WriteLine : string * obj * obj * obj * obj -> unit

Public Shared Sub WriteLine (format As String, arg0 As Object, arg1 As Object, arg2 As Object, arg3 As Object)

매개 변수

format: String

복합 형식 문자열입니다.A composite format string.

arg0: Object

format을 사용하여 쓸 첫 번째 개체입니다.The first object to write using format.

arg1: Object

format을 사용하여 쓸 두 번째 개체입니다.The second object to write using format.

arg2: Object

format을 사용하여 쓸 세 번째 개체입니다.The third object to write using format.

arg3: Object

format을 사용하여 쓸 네 번째 개체입니다.The fourth object to write using format.

특성: CLSCompliantAttribute

예외

IOException

I/O 오류가 발생했습니다.An I/O error occurred.

ArgumentNullException

format이(가) null인 경우format is null.

FormatException

format의 형식 사양이 잘못되었습니다.The format specification in format is invalid.

예제

다음 예제에서는 메서드를 사용 하 여 변수 인수를 사용 하는 방법을 보여 줍니다 WriteLine(String, Object, Object, Object, Object) .The following example illustrates the use of variable arguments with the WriteLine(String, Object, Object, Object, Object) method. 메서드는 복합 형식 문자열과 5 개의 형식 항목을 사용 하 여 호출 됩니다.The method is called with a composite format string and five format items.

using namespace System;

int CountLetters(String^ value);
int CountWhitespace(String^ value);

void main()
{
   String^ value = "This is a test string.";
   
   
   Console::WriteLine("The string '{0}' consists of:" +
                      "{4}{1} characters{4}{2} letters{4}" +
                      "{3} white-space characters", 
                      value, value->Length, CountLetters(value), 
                      CountWhitespace(value), Environment::NewLine);
}

int CountLetters(String^ value)
{
   int nLetters = 0;
   for each (Char ch in value) {
      if (Char::IsLetter(ch))
         nLetters++;
   }
   return nLetters;
}

int CountWhitespace(String^ value)
{
   int nWhitespace = 0;
   for each (Char ch in value) {
      if (Char::IsWhiteSpace(ch))
         nWhitespace++;
   }
   return nWhitespace;
}
// The example displays the following output:
//    The string 'This is a test string.' consists of:
//    22 characters
//    17 letters
//    4 white-space characters

호출자 참고

이 메서드는 키워드를 사용 하 여 vararg 매개 변수 수를 지원함을 의미 합니다.This method is marked with the vararg keyword, which means that it supports a variable number of parameters. Visual C++에서 메서드를 호출할 수 있지만 c # 또는 Visual Basic 코드에서 호출할 수 없습니다.The method can be called from Visual C++, but it cannot be called from C# or Visual Basic code. C # 및 Visual Basic 컴파일러는에 대 한 호출을를 호출 하 여 확인 WriteLine(String, Object, Object, Object, Object) WriteLine(String, Object[]) 합니다.The C# and Visual Basic compilers resolve calls to WriteLine(String, Object, Object, Object, Object) as calls to WriteLine(String, Object[]).
