When overridden in a derived class, searches for a constructor whose parameters match the specified argument types and modifiers, using the specified binding constraints and the specified calling convention.

'Declaration Protected MustOverride Function GetConstructorImpl ( _ bindingAttr As BindingFlags, _ binder As Binder, _ callConvention As CallingConventions, _ types As Type(), _ modifiers As ParameterModifier() _ ) As ConstructorInfo
- Type: System.Reflection.BindingFlags
A bitmask comprised of one or more BindingFlags that specify how the search is conducted.
Zero, to return Nothing.
- Type: System.Reflection.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.
A null reference (Nothing in Visual Basic), to use the DefaultBinder.
- Type: System.Reflection.CallingConventions
The CallingConventions object that specifies the set of rules to use regarding the order and layout of arguments, how the return value is passed, what registers are used for arguments, and the stack is cleaned up.
- Type: System.Type()
An array of Type objects representing the number, order, and type of the parameters for the constructor to get.
An empty array of the type Type (that is, Type types = new Type) to get a constructor that takes no parameters.
types is Nothing.
One of the elements in types is Nothing.
types is multidimensional.
modifiers is multidimensional.
types and modifiers do not have the same length.
Although the default binder does not process ParameterModifier (the modifiers parameter), you can use the abstract System.Reflection.Binder class to write a custom binder that does process modifiers. ParameterModifier is only used when calling through COM interop, and only parameters that are passed by reference are handled.
The types array and the modifiers array have the same length. A parameter specified in the types array can have the following attributes, which are specified in the modifiers array: pdIn, pdOut, pdLcid, pdRetval, pdOptional, and pdHasDefault, which represent [In], [Out], [lcid], [retval], [optional], and a value specifying whether the parameter has a default value. A parameter's associated attributes are stored in the metadata and are used for interoperability.
If an exact match does not exist, the binder will attempt to coerce the parameter types specified in the types array in order to select a match. If the binder is unable to select a match, then Nothing is returned.
The following BindingFlags filter flags can be used to define which constructors to include in the search:
You must specify either BindingFlags.Instance or BindingFlags.Static in order to get a return.
Specify BindingFlags.Public to include public constructors in the search.
Specify BindingFlags.NonPublic to include non-public constructors (that is, private and protected constructors) in the search.
See System.Reflection.BindingFlags for more information.
