_Type.InvokeMember Method

Definition

Provides COM objects with version-independent access to the InvokeMember method.

Overloads

Remarks

This method is for access to managed classes from unmanaged code, and should not be called from managed code.

The Type.InvokeMember method invokes a specific member of the current Type.

.

InvokeMember(String, BindingFlags, Binder, Object, Object[])

Provides COM objects with version-independent access to the InvokeMember(String, BindingFlags, Binder, Object, Object[]) method.

public object InvokeMember (string name, System.Reflection.BindingFlags invokeAttr, System.Reflection.Binder binder, object target, object[] args);

Parameters

name
String

The String containing the name of the constructor, method, property, or field member to invoke.

-or-

An empty string ("") to invoke the default member.

-or-

For IDispatch members, a string representing the DispID, for example "[DispID=3]".

invokeAttr
BindingFlags

A bitmask comprised of one or more BindingFlags that specify how the search is conducted. The access can be one of the BindingFlags such as Public, NonPublic, Private, InvokeMethod, GetField, and so on. The type of lookup need not be specified. If the type of lookup is omitted, BindingFlags.Public | BindingFlags.Instance will apply.

binder
Binder

A Binder object that defines a set of properties and enables binding, which can involve selection of an overloaded method, coercion of argument types, and invocation of a member through reflection.

-or-

null, to use the DefaultBinder.

target
Object

The Object on which to invoke the specified member.

args
Object[]

An array containing the arguments to pass to the member to invoke.

Returns

An Object representing the return value of the invoked member.

Remarks

This method is for access to managed classes from unmanaged code, and should not be called from managed code.

The Type.InvokeMember method invokes the specified member, using the specified binding constraints and matching the specified argument list.

InvokeMember(String, BindingFlags, Binder, Object, Object[], CultureInfo)

Provides COM objects with version-independent access to the InvokeMember(String, BindingFlags, Binder, Object, Object[], CultureInfo) method.

public object InvokeMember (string name, System.Reflection.BindingFlags invokeAttr, System.Reflection.Binder binder, object target, object[] args, System.Globalization.CultureInfo culture);

Parameters

name
String

The String containing the name of the constructor, method, property, or field member to invoke.

-or-

An empty string ("") to invoke the default member.

-or-

For IDispatch members, a string representing the DispID, for example "[DispID=3]".

invokeAttr
BindingFlags

A bitmask comprised of one or more BindingFlags that specify how the search is conducted. The access can be one of the BindingFlags such as Public, NonPublic, Private, InvokeMethod, GetField, and so on. The type of lookup need not be specified. If the type of lookup is omitted, BindingFlags.Public | BindingFlags.Instance will apply.

-or-

null, to use the DefaultBinder.

target
Object

The Object on which to invoke the specified member.

args
Object[]

An array containing the arguments to pass to the member to invoke.

culture
CultureInfo

The CultureInfo object representing the globalization locale to use, which may be necessary for locale-specific conversions, such as converting a numeric String to a Double.

-or-

null to use the current thread's CultureInfo.

Returns

An Object representing the return value of the invoked member.

Remarks

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

Provides COM objects with version-independent access to the InvokeMember(String, BindingFlags, Binder, Object, Object[], ParameterModifier[], CultureInfo, String[]) method.

public 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);

Parameters

name
String

The String containing the name of the constructor, method, property, or field member to invoke.

-or-

An empty string ("") to invoke the default member.

-or-

For IDispatch members, a string representing the DispID, for example "[DispID=3]".

invokeAttr

target
Object

The Object on which to invoke the specified member.

args
Object[]

An array containing the arguments to pass to the member to invoke.

modifiers
ParameterModifier[]

An array of ParameterModifier objects representing the attributes associated with the corresponding element in the args array. A parameter's associated attributes are stored in the member's signature. The default binder does not process this parameter.

culture
CultureInfo

-or-

null to use the current thread's CultureInfo.

namedParameters
String[]

An array containing the names of the parameters to which the values in the args array are passed.

Returns

An Object representing the return value of the invoked member.
