GetGenericArguments()

Returns an array of Type objects that represent the type arguments of a generic method or the type parameters of a generic method definition.

Declaration

public override Type[] GetGenericArguments()

Returns

Type	Description
Type[]	An array of Type objects that represent the type arguments of a generic method or the type parameters of a generic method definition. Returns an empty array if the current method is not a generic method.

Overrides

MethodInfo.GetGenericArguments()

Exceptions

Type	Condition
NotSupportedException	This method is not supported.

GetMethodImplementationFlags()

When overridden in a derived class, returns the MethodImplAttributes flags.

Declaration

public override MethodImplAttributes GetMethodImplementationFlags()

Returns

Type	Description
MethodImplAttributes	The MethodImplAttributes flags.

Overrides

MethodBase.GetMethodImplementationFlags()

GetParameters()

When overridden in a derived class, gets the parameters of the specified method or constructor.

Declaration

public override ParameterInfo[] GetParameters()

Returns

Type	Description
ParameterInfo[]	An array of type ParameterInfo containing information that matches the signature of the method (or constructor) reflected by this MethodBase instance.

Overrides

Invoke(object, BindingFlags, Binder, object[], CultureInfo)

When overridden in a derived class, invokes the reflected method or constructor with the given parameters.

Declaration

public override object Invoke(object obj, BindingFlags invokeAttr, Binder binder, object[] parameters, CultureInfo culture)

Parameters

Type	Name	Description
object	obj	The object on which to invoke the method or constructor. If a method is static, this argument is ignored. If a constructor is static, this argument must be null or an instance of the class that defines the constructor.
BindingFlags	invokeAttr	A bitmask that is a combination of 0 or more bit flags from BindingFlags. If binder is null, this parameter is assigned the value Default; thus, whatever you pass in is ignored.
Binder	binder	An object that enables the binding, coercion of argument types, invocation of members, and retrieval of MemberInfo objects via reflection. If binder is null, the default binder is used.
object[]	parameters	An argument list for the invoked method or constructor. This is an array of objects with the same number, order, and type as the parameters of the method or constructor to be invoked. If there are no parameters, this should be null. If the method or constructor represented by this instance takes a ByRef parameter, there is no special attribute required for that parameter in order to invoke the method or constructor using this function. Any object in this array that is not explicitly initialized with a value will contain the default value for that object type. For reference-type elements, this value is null. For value-type elements, this value is 0, 0.0, or false, depending on the specific element type.
CultureInfo	culture	An instance of CultureInfo used to govern the coercion of types. If this is null, the CultureInfo for the current thread is used. (This is necessary to convert a string that represents 1000 to a double value, for example, since 1000 is represented differently by different cultures.)

Returns

Type	Description
object	An Object containing the return value of the invoked method, or null in the case of a constructor, or null if the method's return type is void. Before calling the method or constructor, Invoke checks to see if the user has access permission and verifies that the parameters are valid.

Overrides

MethodBase.Invoke(object, BindingFlags, Binder, object[], CultureInfo)

Exceptions

Type	Condition
TargetException	The obj parameter is null and the method is not static. -or- The method is not declared or inherited by the class of obj. -or- A static constructor is invoked, and obj is neither null nor an instance of the class that declared the constructor.
ArgumentException	The type of the parameters parameter does not match the signature of the method or constructor reflected by this instance.
TargetParameterCountException	The parameters array does not have the correct number of arguments.
TargetInvocationException	The invoked method or constructor throws an exception.
MethodAccessException	The caller does not have permission to execute the method or constructor that is represented by the current instance.
InvalidOperationException	The type that declares the method is an open generic type. That is, the ContainsGenericParameters property returns true for the declaring type.

IsDefined(Type, bool)

When overridden in a derived class, indicates whether one or more attributes of the specified type or of its derived types is applied to this member.

Declaration

public override bool IsDefined(Type attributeType, bool inherit)

Parameters

Type	Name	Description
Type	attributeType	The type of custom attribute to search for. The search includes derived types.
bool	inherit	true to search this member's inheritance chain to find the attributes; otherwise, false. This parameter is ignored for properties and events.

Returns

Type	Description
bool	true if one or more instances of attributeType or any of its derived types is applied to this member; otherwise, false.

Overrides

MemberInfo.IsDefined(Type, bool)

MakeGenericMethod(params Type[])

Substitutes the elements of an array of types for the type parameters of the current generic method definition, and returns a MethodInfo object representing the resulting constructed method.

Declaration

public override MethodInfo MakeGenericMethod(params Type[] typeArguments)

Parameters

Type	Name	Description
Type[]	typeArguments	An array of types to be substituted for the type parameters of the current generic method definition.

Returns

Type	Description
MethodInfo	A MethodInfo object that represents the constructed method formed by substituting the elements of typeArguments for the type parameters of the current generic method definition.

Overrides

MethodInfo.MakeGenericMethod(params Type[])

Exceptions

Type	Condition
InvalidOperationException	The current MethodInfo does not represent a generic method definition. That is, IsGenericMethodDefinition returns false.
ArgumentNullException	typeArguments is null. -or- Any element of typeArguments is null.
ArgumentException	The number of elements in typeArguments is not the same as the number of type parameters of the current generic method definition. -or- An element of typeArguments does not satisfy the constraints specified for the corresponding type parameter of the current generic method definition.
NotSupportedException	This method is not supported.

ToString()

Returns a string that represents the current object.

Declaration

public override string ToString()

Returns

Type	Description
string	A string that represents the current object.
