Microsoft ResX Schema
|
||||||
|
|
||||||
|
Version 2.0
|
||||||
|
|
||||||
|
The primary goals of this format is to allow a simple XML format
|
||||||
|
that is mostly human readable. The generation and parsing of the
|
||||||
|
various data types are done through the TypeConverter classes
|
||||||
|
associated with the data types.
|
||||||
|
|
||||||
|
Example:
|
||||||
|
|
||||||
|
... ado.net/XML headers & schema ...
|
||||||
|
<resheader name="resmimetype">text/microsoft-resx</resheader>
|
||||||
|
<resheader name="version">2.0</resheader>
|
||||||
|
<resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
|
||||||
|
<resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
|
||||||
|
<data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
|
||||||
|
<data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
|
||||||
|
<data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
|
||||||
|
<value>[base64 mime encoded serialized .NET Framework object]</value>
|
||||||
|
</data>
|
||||||
|
<data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
|
||||||
|
<value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
|
||||||
|
<comment>This is a comment</comment>
|
||||||
|
</data>
|
||||||
|
|
||||||
|
There are any number of "resheader" rows that contain simple
|
||||||
|
name/value pairs.
|
||||||
|
|
||||||
|
Each data row contains a name, and value. The row also contains a
|
||||||
|
type or mimetype. Type corresponds to a .NET class that support
|
||||||
|
text/value conversion through the TypeConverter architecture.
|
||||||
|
Classes that don't support this are serialized and stored with the
|
||||||
|
mimetype set.
|
||||||
|
|
||||||
|
The mimetype is used for serialized objects, and tells the
|
||||||
|
ResXResourceReader how to depersist the object. This is currently not
|
||||||
|
extensible. For a given mimetype the value must be set accordingly:
|
||||||
|
|
||||||
|
Note - application/x-microsoft.net.object.binary.base64 is the format
|
||||||
|
that the ResXResourceWriter will generate, however the reader can
|
||||||
|
read any of the formats listed below.
|
||||||
|
|
||||||
|
mimetype: application/x-microsoft.net.object.binary.base64
|
||||||
|
value : The object must be serialized with
|
||||||
|
: System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
|
||||||
|
: and then encoded with base64 encoding.
|
||||||
|
|
||||||
|
mimetype: application/x-microsoft.net.object.soap.base64
|
||||||
|
value : The object must be serialized with
|
||||||
|
: System.Runtime.Serialization.Formatters.Soap.SoapFormatter
|
||||||
|
: and then encoded with base64 encoding.
|
||||||
|
|
||||||
|
mimetype: application/x-microsoft.net.object.bytearray.base64
|
||||||
|
value : The object must be serialized into a byte array
|
||||||
|
: using a System.ComponentModel.TypeConverter
|
||||||
|
: and then encoded with base64 encoding.
