Type.GetMethod Method (String, Type[], ParameterModifier[])

Updated: September 2009

Searches for the specified public method whose parameters match the specified argument types and modifiers.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public MethodInfo GetMethod(
	string name,
	Type[] types,
	ParameterModifier[] modifiers
)

Parameters

name
Type: System.String

The String containing the name of the public method to get.

types
Type: System.Type[]

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

-or-

An empty array of Type objects (as provided by the EmptyTypes field) to get a method that takes no parameters.

modifiers
Type: System.Reflection.ParameterModifier[]

An array of ParameterModifier objects representing the attributes associated with the corresponding element in the types array. To be only used when calling through COM interop, and only parameters that are passed by reference are handled. The default binder does not process this parameter.

Return Value

Type: System.Reflection.MethodInfo
A MethodInfo object representing the public method that matches the specified requirements, if found; otherwise, null.

Implements

_Type.GetMethod(String, Type[], ParameterModifier[])

ExceptionCondition
AmbiguousMatchException

More than one method is found with the specified name and specified parameters.

ArgumentNullException

name is null.

-or-

types is null.

-or-

One of the elements in types is null.

ArgumentException

types is multidimensional.

-or-

modifiers is multidimensional.

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 search for name is case-sensitive. The search includes public static and public instance methods.

NoteNote:

You cannot omit parameters when looking up constructors and methods. You can only omit parameters when invoking.

If the current T:System.Type represents a constructed generic type, this method returns the MethodInfo with the type parameters replaced by the appropriate type arguments.

If the current Type represents a type parameter in the definition of a generic type or generic method, this method searches the methods of the class constraint, or the methods of Object if there is no class constraint.

NoteNote:

For generic methods, do not include the type arguments in name. For example, the C# code GetMember("MyMethod<int>") searches for a member with the text name "MyMethod<int>", rather than for a method named MyMethod that has one generic argument of type int.

Removed an erroneous statement that null is returned for non-public members outside the assembly, if caller lacks ReflectionPermission.
