Konstruktory

GacMembershipCondition()

Inicializuje novou instanci GacMembershipCondition třídy .

Metody

Check(Evidence)	Určuje, zda zadaný důkaz splňuje podmínku členství.
Copy()	Vytvoří ekvivalentní kopii podmínky členství.
Equals(Object)	Určuje, zda je aktuální objekt ekvivalentní zadanému objektu.
FromXml(SecurityElement)	Použije zadané kódování XML k rekonstrukci objektu zabezpečení.
FromXml(SecurityElement, PolicyLevel)	Použije zadané kódování XML k rekonstrukci objektu zabezpečení pomocí zadaného kontextu na úrovni zásad.
GetHashCode()	Získá kód hash pro aktuální podmínku členství.
GetType()	Type Získá z aktuální instance. (Zděděno od Object)
MemberwiseClone()	Vytvoří mělkou kopii aktuálního Objectsouboru . (Zděděno od Object)
ToString()	Vrátí řetězcovou reprezentaci podmínky členství.
ToXml()	Vytvoří kódování XML objektu zabezpečení a jeho aktuální stav.
ToXml(PolicyLevel)	Vytvoří kódování XML objektu zabezpečení a jeho aktuální stav pomocí zadaného kontextu na úrovni zásad.
