XmlWriter.WriteBinHex(Byte[], Int32, Int32) XmlWriter.WriteBinHex(Byte[], Int32, Int32) XmlWriter.WriteBinHex(Byte[], Int32, Int32) XmlWriter.WriteBinHex(Byte[], Int32, Int32) Method

정의

파생 클래스에서 재정의되면 지정된 이진 바이트를 BinHex로 인코딩하고 결과 텍스트를 작성합니다.When overridden in a derived class, encodes the specified binary bytes as BinHex and writes out the resulting text.

public:
 virtual void WriteBinHex(cli::array <System::Byte> ^ buffer, int index, int count);
public virtual void WriteBinHex (byte[] buffer, int index, int count);
abstract member WriteBinHex : byte[] * int * int -> unit
override this.WriteBinHex : byte[] * int * int -> unit
Public Overridable Sub WriteBinHex (buffer As Byte(), index As Integer, count As Integer)

매개 변수

buffer
Byte[]

인코딩할 바이트 배열입니다.Byte array to encode.

index
Int32 Int32 Int32 Int32

쓸 바이트의 시작을 나타내는 버퍼 내의 위치입니다.The position in the buffer indicating the start of the bytes to write.

count
Int32 Int32 Int32 Int32

쓸 바이트 수입니다.The number of bytes to write.

예외

작성기가 닫혀 있거나 오류가 발생한 경우The writer is closed or in error state. 또는-or-

이전 비동기 작업이 완료되기 전에 XmlWriter 메서드가 호출되었습니다.An XmlWriter method was called before a previous asynchronous operation finished. 이 경우 “비동기 작업이 이미 진행 중입니다.” 메시지를 나타내며 InvalidOperationException이 throw됩니다.In this case, InvalidOperationException is thrown with the message "An asynchronous operation is already in progress."

index 또는 count가 0보다 작습니다.index or count is less than zero.

또는-or- 버퍼 길이에서 index를 빼면 count보다 작습니다.The buffer length minus index is less than count.

예제

다음 예제에서는 합니다 WriteBinHex 메서드를 BinHex 데이터입니다.The following example uses the WriteBinHex method to write BinHex data. BinHex 내에 포함 된 데이터는 <image> 요소입니다.The BinHex data is embedded within an <image> element.


public static void BinHexEncodeImageFile() {

  int bufferSize = 1000;
  byte[] buffer = new byte[bufferSize];
  int readBytes = 0;
	
  using (XmlWriter writer = XmlWriter.Create("output.xml")) {
       FileStream inputFile = new FileStream(@"C:\artFiles\sunset.jpg", FileMode.OpenOrCreate, 
                                                                    FileAccess.Read, FileShare.Read);
       writer.WriteStartDocument();
       writer.WriteStartElement("image");
       BinaryReader br = new BinaryReader(inputFile);
       Console.WriteLine("\r\nWriting BinHex data...");

       do {
          readBytes = br.Read(buffer, 0, bufferSize);
          writer.WriteBinHex(buffer, 0, readBytes);
       } while (bufferSize <= readBytes);
       br.Close();

    writer.WriteEndElement();// </image>
    writer.WriteEndDocument();
		
  }
}
Public Shared Sub BinHexEncodeImageFile() 
    
    Dim bufferSize As Integer = 1000
    Dim buffer(bufferSize) As Byte
    Dim readBytes As Integer = 0
    
    Using writer As XmlWriter = XmlWriter.Create("output.xml")

            Dim inputFile As New FileStream("C:\artFiles\sunset.jpg", FileMode.OpenOrCreate, FileAccess.Read, FileShare.Read)
            writer.WriteStartDocument()
            writer.WriteStartElement("image")
            Dim br As New BinaryReader(inputFile)
            Console.WriteLine(vbCr + vbLf + "Writing BinHex data...")
            
            Do
                readBytes = br.Read(buffer, 0, bufferSize)
                writer.WriteBinHex(buffer, 0, readBytes)
            Loop While bufferSize <= readBytes
