WriteBinHex Method

XmlWriter.WriteBinHex Method

When overridden in a derived class, encodes the specified binary bytes as BinHex and writes out the resulting text.

Namespace:  System.Xml
Assembly:  System.Xml (in System.Xml.dll)

public virtual void WriteBinHex(
	byte[] buffer,
	int index,
	int count
)

Parameters

buffer
Type: System.Byte[]

Byte array to encode.

index
Type: System.Int32

The position in the buffer indicating the start of the bytes to write.

count
Type: System.Int32

The number of bytes to write.

ExceptionCondition
ArgumentNullException

buffer is null.

InvalidOperationException

The writer is closed or in error state.

ArgumentOutOfRangeException

index or count is less than zero.

-or-

The buffer length minus index is less than count.

The following example uses the WriteBinHex method to write BinHex data. 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();
		
  }
}
