Microsoft ResX Schema
5+
6+
Version 2.0
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">2.0</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"><value>this is my long string</value><comment>this is a comment</comment></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+
<value>[base64 mime encoded serialized .NET Framework object]</value>
24+
</data>
25+
<data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
26+
<value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
27+
<comment>This is a comment</comment>
28+
</data>
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.
