Type.GetMethod Method (String, Type[])


The .NET API Reference documentation has a new home. Visit the .NET API Browser on docs.microsoft.com to see the new experience.

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

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

abstract GetMethod : 
        name:string *
        types:Type[] -> MethodInfo
override GetMethod : 
        name:string *
        types:Type[] -> MethodInfo


Type: System.String

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

Type: System.Type[]

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


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

Return Value

Type: System.Reflection.MethodInfo

An object representing the public method whose parameters match the specified argument types, if found; otherwise, null.

Exception Condition

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


name is null.


types is null.


One of the elements in types is null.


types is multidimensional.

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


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

If the current 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.


The name parameter cannot include type arguments. For example, the C# code GetMethod("MyGenericMethod<int>") searches for a method with the text name "MyGenericMethod<int>", rather than for a method named MyGenericMethod that has one generic argument of type int. Instead, use GetMethod("MyGenericMethod") with the appropriate parameter in the types array.

The following example finds specific overloads of MethodA, specifying a variety of argument types.


The Visual C# 2005 example requires the /unsafe compiler option.

No code example is currently available or this language may not be supported.

The following example retrieves MethodInfo objects that represent the Add methods of a non-generic type (the ArrayList class), an open generic type (the List<'T> class), and a closed generic type (the List(Of String) type.

No code example is currently available or this language may not be supported.

The example defines a GetAddMethod method that retrieves the appropriate MethodInfo object. To provide the types argument for an open generic type, it calls the Type.GetGenericArguments method. To provide the types argument for a closed generic type, it retrieves the value of the Type.GenericTypeArguments property.
