Type.GetMethod Method (String, Type())

Updated: September 2009

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

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

Public Function GetMethod ( _
	name As String, _
	types As Type() _
) As MethodInfo
Dim instance As Type 
Dim name As String 
Dim types As Type()
Dim returnValue As MethodInfo 

returnValue = instance.GetMethod(name, _


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
A MethodInfo object representing the public method whose parameters match the specified argument types, if found; otherwise, Nothing.


_Type.GetMethod(String, Type())


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


name is Nothing.


types is Nothing.


One of the elements in types is Nothing.


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 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.


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.

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


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

Imports System.Runtime.InteropServices

    ' Methods to get: 

    Public Overloads Sub MethodA(ByVal i As Integer, ByVal l As Long)

    End Sub

    ' Method that takes an out parameter. Note that an Imports 
    ' reference is needed to System.Runtime.InteropServices  
    ' for the <OutAttribute>, which can be shortened to <Out>. 
    Public Overloads Sub MethodA(ByVal i As Integer, <Out()> ByRef o As Integer)
        o = 100
    End Sub 

    Public Shared Sub Main(ByVal args() As String)
        Dim mInfo As MethodInfo

        ' Get MethodA(i As Integer i, l As Long)
        mInfo = GetType(Program).GetMethod("MethodA", New Type() {GetType(Integer), GetType(Long)})
        Console.WriteLine("Found method: {0}", mInfo)

        ' Get  MethodA(i As Integer())
        mInfo = GetType(Program).GetMethod("MethodA", New Type() {GetType(Integer())})
        Console.WriteLine("Found method: {0}", mInfo)

        ' Get MethodA(ByRef r As Integer)
        mInfo = GetType(Program).GetMethod("MethodA", New Type() {GetType(Integer).MakeByRefType})
        Console.WriteLine("Found method: {0}", mInfo)

        ' Get MethodA(i As Integer, ByRef r As Integer)
        mInfo = GetType(Program).GetMethod("MethodA", New Type() {GetType(Integer), _
        Console.WriteLine("Found method: {0}", mInfo)

Removed an erroneous statement that Nothing is returned for non-public members outside the assembly, if caller lacks ReflectionPermission.
