Esempi

Nell'esempio seguente viene ottenuto MemberFilter il delegato, passato come parametro FindMembers al metodo e vengono visualizzati i metodi String e i relativi attributi della classe che iniziano con la lettera "c", indipendentemente dal caso.The following example gets the MemberFilter delegate, passes it as a parameter to the FindMembers method, and displays the methods and their attributes of the String class that begin with the letter "c", disregarding the case.

Commenti

Questo campo include un riferimento al delegato utilizzato dal FindMembers metodo.This field holds a reference to the delegate used by the FindMembers method. Il metodo incapsulato da questo delegato accetta due parametri: il primo è MemberInfo un oggetto e il secondo Objectè.The method encapsulated by this delegate takes two parameters: the first is a MemberInfo object and the second is an Object. Il metodo determina se l' MemberInfo oggetto corrisponde ai criteri specificati Objectda.The method determines whether the MemberInfo object matches the criteria specified by the Object. Al Object viene assegnato un valore stringa, che può includere un carattere jolly "*" finale.The Object is assigned a string value, which may include a trailing "*" wildcard character. È supportata solo la corrispondenza di stringhe finali con caratteri jolly.Only wildcard end string matching is supported.

Ad esempio, Object può essere assegnato il valore "byte *".For example, the Object may be assigned the value "ByTe*". In tal caso, quando viene FilterName richiamato il delegato, viene restituito true solo se il metodo rappresentato MemberInfo dall'oggetto ha un nome che inizia con "byte", ignorando la distinzione tra maiuscole e minuscole.In that case, when the FilterName delegate is invoked, it will return true only if the method represented by the MemberInfo object has a name that begins with "byte", ignoring case.
