Dynamically invokes the method reflected by this instance on the given object, passing along the specified parameters, and under the constraints of the given binder.

public:
 override System::Object ^ Invoke(System::Object ^ obj, System::Reflection::BindingFlags invokeAttr, System::Reflection::Binder ^ binder, cli::array <System::Object ^> ^ parameters, System::Globalization::CultureInfo ^ culture);

public override object Invoke (object? obj, System.Reflection.BindingFlags invokeAttr, System.Reflection.Binder? binder, object?[]? parameters, System.Globalization.CultureInfo? culture);

public override object Invoke (object obj, System.Reflection.BindingFlags invokeAttr, System.Reflection.Binder binder, object[] parameters, System.Globalization.CultureInfo culture);

override this.Invoke : obj * System.Reflection.BindingFlags * System.Reflection.Binder * obj[] * System.Globalization.CultureInfo -> obj

Public Overrides Function Invoke (obj As Object, invokeAttr As BindingFlags, binder As Binder, parameters As Object(), culture As CultureInfo) As Object

Parameters

obj: Object

The object on which to invoke the specified method. If the method is static, this parameter is ignored.

invokeAttr: BindingFlags

This must be a bit flag from BindingFlags : InvokeMethod, NonPublic, and so on.

binder: Binder

An object that enables the binding, coercion of argument types, invocation of members, and retrieval of MemberInfo objects via reflection. If binder is null, the default binder is used. For more details, see Binder.

parameters: Object[]

An argument list. This is an array of arguments with the same number, order, and type as the parameters of the method to be invoked. If there are no parameters this should be null.

culture: CultureInfo

An instance of CultureInfo used to govern the coercion of types. If this is null, the CultureInfo for the current thread is used. (Note that this is necessary to, for example, convert a String that represents 1000 to a Double value, since 1000 is represented differently by different cultures.)

Returns

Object

Returns an object containing the return value of the invoked method.

Exceptions

NotSupportedException

This method is not currently supported. Retrieve the method using GetMethod(String, BindingFlags, Binder, CallingConventions, Type[], ParameterModifier[]) and call InvokeMember(String, BindingFlags, Binder, Object, Object[], ParameterModifier[], CultureInfo, String[]) on the returned MethodInfo.

Remarks

If the method is static, the obj parameter is ignored. For non-static methods, obj should be an instance of a class that inherits or declares the method and must be the same type as this class. If the method has no parameters, the value of parameters should be null. Otherwise the number, type, and order of elements in the parameters array should be identical to the number, type, and order of parameters for the method reflected by this instance.

Note

Access restrictions are ignored for fully-trusted code. That is, private constructors, methods, fields, and properties can be accessed and invoked using Reflection whenever the code is fully-trusted.
