_Type.GetConstructor Method

Definition

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

Overloads

GetConstructor(BindingFlags, Binder, CallingConventions, Type[], ParameterModifier[])

Provides COM objects with version-independent access to the GetConstructor(BindingFlags, Binder, CallingConventions, Type[], ParameterModifier[]) method.

GetConstructor(BindingFlags, Binder, Type[], ParameterModifier[])

Provides COM objects with version-independent access to the GetConstructor(BindingFlags, Binder, Type[], ParameterModifier[]) method.

GetConstructor(Type[])

Provides COM objects with version-independent access to the GetConstructor(Type[]) method.

Remarks

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

The Type.GetConstructor method gets a specific constructor of the current Type.

GetConstructor(BindingFlags, Binder, CallingConventions, Type[], ParameterModifier[])

Provides COM objects with version-independent access to the GetConstructor(BindingFlags, Binder, CallingConventions, Type[], ParameterModifier[]) method.

public:
 System::Reflection::ConstructorInfo ^ GetConstructor(System::Reflection::BindingFlags bindingAttr, System::Reflection::Binder ^ binder, System::Reflection::CallingConventions callConvention, cli::array <Type ^> ^ types, cli::array <System::Reflection::ParameterModifier> ^ modifiers);
public System.Reflection.ConstructorInfo GetConstructor (System.Reflection.BindingFlags bindingAttr, System.Reflection.Binder binder, System.Reflection.CallingConventions callConvention, Type[] types, System.Reflection.ParameterModifier[] modifiers);
abstract member GetConstructor : System.Reflection.BindingFlags * System.Reflection.Binder * System.Reflection.CallingConventions * Type[] * System.Reflection.ParameterModifier[] -> System.Reflection.ConstructorInfo

Parameters

bindingAttr
BindingFlags

A bitmask comprised of one or more BindingFlags that specify how the search is conducted.

-or-

Zero, to return null.

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.

callConvention
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.

types
Type[]

An array of Type objects representing the number, order, and type of the parameters for the constructor to get.

-or-

An empty array of the type Type (that is, Type[] types = new Type[0]) to get a constructor that takes no parameters.

modifiers
ParameterModifier[]

An array of ParameterModifier objects representing the attributes associated with the corresponding element in the types array. The default binder does not process this parameter.

Returns

A ConstructorInfo object representing the constructor that matches the specified requirements, if found; otherwise, null.

Remarks

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

The Type.GetConstructor method searches for a constructor whose parameters match the specified argument types and modifiers, using the specified binding constraints and the specified calling convention.

GetConstructor(BindingFlags, Binder, Type[], ParameterModifier[])

Provides COM objects with version-independent access to the GetConstructor(BindingFlags, Binder, Type[], ParameterModifier[]) method.

public:
 System::Reflection::ConstructorInfo ^ GetConstructor(System::Reflection::BindingFlags bindingAttr, System::Reflection::Binder ^ binder, cli::array <Type ^> ^ types, cli::array <System::Reflection::ParameterModifier> ^ modifiers);
public System.Reflection.ConstructorInfo GetConstructor (System.Reflection.BindingFlags bindingAttr, System.Reflection.Binder binder, Type[] types, System.Reflection.ParameterModifier[] modifiers);
abstract member GetConstructor : System.Reflection.BindingFlags * System.Reflection.Binder * Type[] * System.Reflection.ParameterModifier[] -> System.Reflection.ConstructorInfo

Parameters

bindingAttr
BindingFlags

A bitmask comprised of one or more BindingFlags that specify how the search is conducted.

-or-

Zero, to return null.

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.

types
Type[]

An array of Type objects representing the number, order, and type of the parameters for the constructor to get.

-or-

An empty array of the type Type (that is, Type[] types = new Type[0]) to get a constructor that takes no parameters.

-or-

EmptyTypes.

modifiers
ParameterModifier[]

An array of ParameterModifier objects representing the attributes associated with the corresponding element in the parameter type array. The default binder does not process this parameter.

Returns

A ConstructorInfo object representing the constructor that matches the specified requirements, if found; otherwise, null.

Remarks

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

The Type.GetConstructor method searches for a constructor whose parameters match the specified argument types and modifiers, using the specified binding constraints.

GetConstructor(Type[])

Provides COM objects with version-independent access to the GetConstructor(Type[]) method.

public:
 System::Reflection::ConstructorInfo ^ GetConstructor(cli::array <Type ^> ^ types);
public System.Reflection.ConstructorInfo GetConstructor (Type[] types);
abstract member GetConstructor : Type[] -> System.Reflection.ConstructorInfo
Public Function GetConstructor (types As Type()) As ConstructorInfo

Parameters

types
Type[]

An array of Type objects representing the number, order, and type of the parameters for the desired constructor.

-or-

An empty array of Type objects, to get a constructor that takes no parameters. Such an empty array is provided by the static field EmptyTypes.

Returns

A ConstructorInfo object representing the public instance constructor whose parameters match the types in the parameter type array, if found; otherwise, null.

Remarks

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

The Type.GetConstructor method searches for a public instance constructor whose parameters match the types in the specified array.
