TypeBuilder.InvokeMember(String, BindingFlags, Binder, Object, Object[], ParameterModifier[], CultureInfo, String[]) TypeBuilder.InvokeMember(String, BindingFlags, Binder, Object, Object[], ParameterModifier[], CultureInfo, String[]) TypeBuilder.InvokeMember(String, BindingFlags, Binder, Object, Object[], ParameterModifier[], CultureInfo, String[]) Method

Definition

Invokes the specified member. The method that is to be invoked must be accessible and provide the most specific match with the specified argument list, under the constraints of the specified binder and invocation attributes.

public:
 override System::Object ^ InvokeMember(System::String ^ name, System::Reflection::BindingFlags invokeAttr, System::Reflection::Binder ^ binder, System::Object ^ target, cli::array <System::Object ^> ^ args, cli::array <System::Reflection::ParameterModifier> ^ modifiers, System::Globalization::CultureInfo ^ culture, cli::array <System::String ^> ^ namedParameters);
public override object InvokeMember (string name, System.Reflection.BindingFlags invokeAttr, System.Reflection.Binder binder, object target, object[] args, System.Reflection.ParameterModifier[] modifiers, System.Globalization.CultureInfo culture, string[] namedParameters);
override this.InvokeMember : string * System.Reflection.BindingFlags * System.Reflection.Binder * obj * obj[] * System.Reflection.ParameterModifier[] * System.Globalization.CultureInfo * string[] -> obj

Parameters

name
String String String

The name of the member to invoke. This can be a constructor, method, property, or field. A suitable invocation attribute must be specified. Note that it is possible to invoke the default member of a class by passing an empty string as the name of the member.

invokeAttr
BindingFlags BindingFlags BindingFlags

The invocation attribute. This must be a bit flag from BindingFlags.

binder
Binder Binder Binder

An object that enables the binding, coercion of argument types, invocation of members, and retrieval of MemberInfo objects using reflection. If binder is null, the default binder is used. See Binder.

target
Object Object Object

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

args
Object[]

An argument list. This is an array of Objects that contains the number, order, and type of the parameters of the member to be invoked. If there are no parameters this should be null.

modifiers
ParameterModifier[]

An array of the same length as args with elements that represent the attributes associated with the arguments of the member to be invoked. A parameter has attributes associated with it in the metadata. They are used by various interoperability services. See the metadata specs for more details.

culture
CultureInfo CultureInfo 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.)

namedParameters
String[]

Each parameter in the namedParameters array gets the value in the corresponding element in the args array. If the length of args is greater than the length of namedParameters, the remaining argument values are passed in order.

Returns

Returns the return value of the invoked member.

Exceptions

This method is not currently supported for incomplete types.

Remarks

A method will be invoked if the number of parameters in the method declaration equals the number of arguments in the specified argument list, and the type of each argument can be converted by the binder to the type of the parameter.

The binder will find all of the matching methods. These methods are found based on the type of binding requested (BindingFlags.InvokeMethod, BindingFlags.GetProperties, and so on.). The set of methods is filtered by the name, number of arguments, and a set of search modifiers defined in the binder. After the method is selected, it will be invoked. Accessibility is checked at that point. The search can control which set of methods are searched based upon the accessibility attribute associated with the method. The IBinder.BindToMethod method is responsible for selecting the method to be invoked. The default binder selects the most specific match.

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.

This method is not currently supported. You can retrieve the type using Type.GetType or Assembly.GetType and use reflection on the retrieved type.
