The generation and parsing of the various data types are done through the TypeConverter classes associated with the data types.

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. --> <xsd:schema id="root" xmlns="" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata"> <xsd:import namespace="http://www.w3.org/XML/1998/namespace" /> <xsd:element name="root" msdata:IsDataSet="true"> <xsd:complexType> <xsd:choice maxOccurs="unbounded"> <xsd:element name="metadata"> <xsd:complexType> <xsd:sequence> <xsd:element name="value" type="xsd:string" minOccurs="0" /> </xsd:sequence> <xsd:attribute name="name" use="required" type="xsd:string" /> <xsd:attribute name="type" type="xsd:string" /> <xsd:attribute name="mimetype" type="xsd:string" /> <xsd:attribute ref="xml:space" /> </xsd:complexType> </xsd:element> <xsd:element name="assembly"> <xsd:complexType> <xsd:attribute name="alias" type="xsd:string" /> <xsd:attribute name="name" type="xsd:string" /> </xsd:complexType> </xsd:element> <xsd:element name="data"> <xsd:complexType> <xsd:sequence> <xsd:element name="value" type="xsd:string" minOccurs="0" msdata:Ordinal="1" /> <xsd:element name="comment" type="xsd:string" minOccurs="0" msdata:Ordinal="2" /> </xsd:sequence> <xsd:attribute name="name" type="xsd:string" use="required" msdata:Ordinal="1" /> <xsd:attribute name="type" type="xsd:string" msdata:Ordinal="3" /> <xsd:attribute name="mimetype" type="xsd:string" msdata:Ordinal="4" /> <xsd:attribute ref="xml:space" /> </xsd:complexType> </xsd:element> <xsd:element name="resheader"> <xsd:complexType> <xsd:sequence> <xsd:element name="value" type="xsd:string" minOccurs="0" msdata:Ordinal="1" /> </xsd:sequence> <xsd:attribute name="name" type="xsd:string" use="required" /> </xsd:complexType> </xsd:element> </xsd:choice> </xsd:complexType> </xsd:element> </xsd:schema> <resheader name="resmimetype"> <value>text/microsoft-resx</value> </resheader> <resheader name="version"> <value>2.0</value> </resheader> <resheader name="reader"> <value>System.Resources.ResXResourceReader, System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089</value> </resheader> <resheader name="writer"> <value>System.Resources.ResXResourceWriter, System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089</value> </resheader> <data name="axHWPenSign1.OcxState" mimetype="application/x-microsoft.net.object.binary.base64"> <value> AAEAAAD/////AQAAAAAAAAAMAgAAAFdTeXN0ZW0uV2luZG93cy5Gb3JtcywgVmVyc2lvbj00LjAuMC4w LCBDdWx0dXJlPW5ldXRyYWwsIFB1YmxpY0tleVRva2VuPWI3N2E1YzU2MTkzNGUwODkFAQAAACFTeXN0 ZW0uV2luZG93cy5Gb3Jtcy5BeEhvc3QrU3RhdGUBAAAABERhdGEHAgIAAAAJAwAAAA8DAAAAJQAAAAIB AAAAAQAAAAAAAAAAAAAAABAAAAAAAAEAUj4AAE4rAAAAAAAACw==</value> </data></root>
