this["value"] ??

[flashheal]

Hallo,

in einem Buch habe ich gerade diesen Code gelesen:

ref class GameServerSection : public Configuration::ConfigurationSection
{
public:
GameServerSection() { }
[ConfigurationPropertyAttribute("Port", IsRequired=true)]
property int Port
{
int get() { return (int)this["Port"]; }
void set(int value) { this["Port"] = value; }
}
[ConfigurationPropertyAttribute("IPAddress", IsRequired=true)]
property String^ IPAddress
{
String^ get() { return (String^)this["IPAddress"]; }
void set(String^ value) { this["IPAddress"] = value; }
}
[ConfigurationPropertyAttribute("Name", IsRequired=true)]
property String^ Name
{
String^ get() { return (String^)this["Name"]; }
void set(String^ value) { this["Name"] = value; }
}
};

Was mir nicht klar ist: was bedeuten denn diese this[string] Dinger? Sind das nicht Indexer? Aber die Klasse hat doch garkeine Indexer?!

Aber deren Basis Klasse?
