Creates an instance of the specified type using the constructor that best matches the specified parameters.
Namespace: SystemAssembly: mscorlib (in mscorlib.dll) Version: 4.0.0.0
Syntax public static Object CreateInstance(
Type type,
BindingFlags bindingAttr,
Binder binder,
Object[] args,
CultureInfo culture
)
Parameters
- type
- Type: SystemType
The type of object to create. - bindingAttr
- Type: System.ReflectionBindingFlags
A combination of zero or more bit flags that affect the search for the type constructor. If bindingAttr is zero, a case-sensitive search for public constructors is conducted. - binder
- Type: System.ReflectionBinder
An object that uses bindingAttr and args to seek and identify the type constructor. If binder is null, the default binder is used. - args
- Type: SystemObject
An array of arguments that match in number, order, and type the parameters of the constructor to invoke. If args is an empty array or null, the constructor that takes no parameters (the default constructor) is invoked. - culture
- Type: System.GlobalizationCultureInfo
Culture-specific information that governs the coercion of args to the formal types declared for the type constructor. If culture is null, the CultureInfo for the current thread is used.
Return Value
Type:
ObjectA reference to the newly created object.
Exceptions Exception | Condition |
---|
ArgumentNullException | type is null. |
ArgumentException | type is not a RuntimeType. -or-type is an open generic type (that is, the ContainsGenericParameters property returns true). |
NotSupportedException | type cannot be a TypeBuilder.-or- Creation of TypedReference, ArgIterator, Void, and RuntimeArgumentHandle types, or arrays of those types, is not supported. -or-The assembly that contains type is a dynamic assembly that was created with Save.-or-The constructor that best matches args has varargs arguments. |
TargetInvocationException | The constructor being called throws an exception. |
MethodAccessException | The caller does not have permission to call this constructor. |
MemberAccessException | Cannot create an instance of an abstract class, or this member was invoked with a late-binding mechanism. |
InvalidComObjectException | The COM type was not obtained through GetTypeFromProgID or GetTypeFromCLSID. |
MissingMethodException | No matching constructor was found. |
COMException | type is a COM object but the class identifier used to obtain the type is invalid, or the identified class is not registered. |
TypeLoadException | type is not a valid type. |
