The profile configuration section belongs to serializeas.

Serializeas is an optional attribute. This attribute is used to set the serialization User Configuration Attribute mode. Its Attribute values include string, XML, binary, and providerspecific. The default serialization mode depends on the specific provider, the actual serial number is determined by the mail program.
Usage: program code <Properties>
<Add name = "MSN" type = "string" Serializeas= "XML"/>
<Add name = "QQ" type = "string" Serializeas= "XML"/>
</Properties>

The propertyvaluesstring in the aspnet_profile table will display XML. I personally think it is easier to set XML to view and modify the program code. <? XML version = "1.0" encoding = "UTF-16"?>
<String> MSN number </string> <? XML version = "1.0" encoding = "UTF-16"?>
<String> QQ number </string>

It can be used normally without serialization. Program code <Properties>
<Add name = "MSN" type = "string"/>
<Add name = "QQ" type = "string"/>
</Properties>

The propertyvaluesstring in the aspnet_profile table shows the string program code MSN number QQ number.

Profile is quite powerful and easy to use. We have a lot of good development experience.
