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. |
