BindingFlags bindingAttr,
Binder binder,
CallingConventions callConvention,
Type[] types,

Parameters
- bindingAttr
- Type: System.ReflectionBindingFlags
A bitmask comprised of one or more BindingFlags that specify how the search is conducted.-or- Zero, to return null. - binder
- Type: System.ReflectionBinder
An 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- A null reference (Nothing in Visual Basic), to use the DefaultBinder. - callConvention
- Type: System.ReflectionCallingConventions
The 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: SystemType
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
- Type: System.ReflectionParameterModifier
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.
Return Value
Type:
ConstructorInfoAn object representing the constructor that matches the specified requirements, if found; otherwise, null.
Exceptions Exception | Condition |
---|
ArgumentNullException | types is null.-or- One of the elements in types is null. |
ArgumentException | types is multidimensional.-or- modifiers is multidimensional.-or- types and modifiers do not have the same length. |
