  5 | 
  6 | 		Version 1.3
  7 | 
  8 | 		The primary goals of this format is to allow a simple XML format 
  9 | 		that is mostly human readable. The generation and parsing of the 
 10 | 		various data types are done through the TypeConverter classes 
 11 | 		associated with the data types.
 12 | 
 13 | 		Example:
 14 | 
 15 | 		... ado.net/XML headers & schema ...
 16 | 		<resheader name="resmimetype">text/microsoft-resx</resheader>
 17 | 		<resheader name="version">1.3</resheader>
 18 | 		<resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
 19 | 		<resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
 20 | 		<data name="Name1">this is my long string</data>
 21 | 		<data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
 22 | 		<data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
 23 | 			[base64 mime encoded serialized .NET Framework object]
 24 | 		</data>
 25 | 		<data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
 26 | 			[base64 mime encoded string representing a byte array form of the .NET Framework object]
 27 | 		</data>
 28 | 
 29 | 		There are any number of "resheader" rows that contain simple 
 30 | 		name/value pairs.
 31 | 
 32 | 		Each data row contains a name, and value. The row also contains a 
 33 | 		type or mimetype. Type corresponds to a .NET class that support 
 34 | 		text/value conversion through the TypeConverter architecture. 
 35 | 		Classes that don't support this are serialized and stored with the 
 36 | 		mimetype set.
 37 | 
 38 | 		The mimetype is used for serialized objects, and tells the 
 39 | 		ResXResourceReader how to depersist the object. This is currently not 
 40 | 		extensible. For a given mimetype the value must be set accordingly:
 41 | 
 42 | 		Note - application/x-microsoft.net.object.binary.base64 is the format 
 43 | 		that the ResXResourceWriter will generate, however the reader can 
 44 | 		read any of the formats listed below.
 45 | 
 46 | 		mimetype: application/x-microsoft.net.object.binary.base64
 47 | 		value   : The object must be serialized with 
 48 | 			: System.Serialization.Formatters.Binary.BinaryFormatter
 49 | 			: and then encoded with base64 encoding.
 50 | 
 51 | 		mimetype: application/x-microsoft.net.object.soap.base64
 52 | 		value   : The object must be serialized with 
 53 | 			: System.Runtime.Serialization.Formatters.Soap.SoapFormatter
 54 | 			: and then encoded with base64 encoding.
 55 | 
 56 | 		mimetype: application/x-microsoft.net.object.bytearray.base64
 57 | 		value   : The object must be serialized into a byte array 
 58 | 			: using a System.ComponentModel.TypeConverter
 59 | 			: and then encoded with base64 encoding.

 29 | 
 30 |     There are any number of "resheader" rows that contain simple
 31 |     name/value pairs.
 32 | 
 33 |     Each data row contains a name, and value. The row also contains a
 34 |     type or mimetype. Type corresponds to a .NET class that support
 35 |     text/value conversion through the TypeConverter architecture.
 36 |     Classes that don't support this are serialized and stored with the
 37 |     mimetype set.
 38 | 
 39 |     The mimetype is used for serialized objects, and tells the
 40 |     ResXResourceReader how to depersist the object. This is currently not
 41 |     extensible. For a given mimetype the value must be set accordingly:
 42 | 
 43 |     Note - application/x-microsoft.net.object.binary.base64 is the format
 44 |     that the ResXResourceWriter will generate, however the reader can
 45 |     read any of the formats listed below.
 46 | 
 47 |     mimetype: application/x-microsoft.net.object.binary.base64
 48 |     value   : The object must be serialized with
 49 |             : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
 50 |             : and then encoded with base64 encoding.
 51 | 
 52 |     mimetype: application/x-microsoft.net.object.soap.base64
 53 |     value   : The object must be serialized with
 54 |             : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
 55 |             : and then encoded with base64 encoding.
 56 | 
 57 |     mimetype: application/x-microsoft.net.object.bytearray.base64
 58 |     value   : The object must be serialized into a byte array
 59 |             : using a System.ComponentModel.TypeConverter
 60 |             : and then encoded with base64 encoding.
