    Properties

    Method

    Gets the method represented by the delegate.

    Declaration
    public MethodInfo Method { get; }
    Property Value
    Type Description
    MethodInfo

    A MethodInfo describing the method represented by the delegate.

    Remarks

    Available only in mscorlib build with support for System.Reflection.

    Target

    Gets the class instance on which the current delegate invokes the instance method.

    Declaration
    public object Target { get; }
    Property Value
    Type Description
    Object

    The object on which the current delegate invokes the instance method, if the delegate represents an instance method; null reference (Nothing in Visual Basic) if the delegate represents a static method.

    Methods

    Combine(Delegate, Delegate)

    Concatenates the invocation lists of two delegates.

    Declaration
    public static extern Delegate Combine(Delegate a, Delegate b)
    Parameters
    Type Name Description
    Delegate a

    The delegate whose invocation list comes first.

    Delegate b

    The delegate whose invocation list comes last.

    Returns
    Type Description
    Delegate

    A new delegate with an invocation list that concatenates the invocation lists of a and b in that order. Returns a if b is null reference (Nothing in Visual Basic), returns b if a is a null reference, and returns a null reference if both a and b are null references.

    Equals(Object)

    Determines whether the specified object and the current delegate are of the same type and share the same targets, methods, and invocation list.

    Declaration
    public extern override bool Equals(object obj)
    Parameters
    Type Name Description
    Object obj

    The object to compare with the current delegate.

    Returns
    Type Description
    Boolean

    true if obj and the current delegate have the same targets, methods, and invocation list; otherwise, false.

    Overrides
    Object.Equals(Object)

    GetInvocationList()

    Returns the invocation list of the delegate.

    Declaration
    public extern virtual Delegate[] GetInvocationList()
    Returns
    Type Description
    Delegate[]

    An array of delegates representing the invocation list of the current delegate.

    Remove(Delegate, Delegate)

    Removes the last occurrence of the invocation list of a delegate from the invocation list of another delegate.

    Declaration
    public static extern Delegate Remove(Delegate source, Delegate value)
    Parameters
    Type Name Description
    Delegate source

    The delegate from which to remove the invocation list of value.

    Delegate value

    The delegate that supplies the invocation list to remove from the invocation list of source.

    Returns
    Type Description
    Delegate

    A new delegate with an invocation list formed by taking the invocation list of source and removing the last occurrence of the invocation list of value, if the invocation list of value is found within the invocation list of source. Returns source if value is null reference (Nothing in Visual Basic) or if the invocation list of value is not found within the invocation list of source. Returns a null reference if the invocation list of value is equal to the invocation list of source or if source is a null reference.

    Operators

    Equality(Delegate, Delegate)

    Determines whether the specified delegates are equal.

    Declaration
    public static extern bool operator ==(Delegate d1, Delegate d2)
    Parameters
    Type Name Description
    Delegate d1

    The first delegate to compare.

    Delegate d2

    The second delegate to compare.

    Returns
    Type Description
    Boolean

    true if d1 is equal to d2; otherwise, false.

    Inequality(Delegate, Delegate)

    Determines whether the specified delegates are not equal.

    Declaration
    public static extern bool operator !=(Delegate d1, Delegate d2)
    Parameters
    Type Name Description
    Delegate d1

    The first delegate to compare.

    Delegate d2

    The second delegate to compare.

    Returns
    Type Description
    Boolean

    true if d1 is not equal to d2; otherwise, false.
