.NET Framework 4
When overridden in a derived class, encodes the specified binary bytes as BinHex and writes out the resulting text.
Assembly: System.Xml (in System.Xml.dll)
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.
| Exception | Condition |

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(); } }
