GetParameters Method

MethodBase.GetParameters Method

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

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

'Declaration
Public MustOverride Function GetParameters As ParameterInfo()

Return Value

Type: System.Reflection.ParameterInfo()
An array of type ParameterInfo containing information that matches the signature of the method (or constructor) reflected by this MethodBase instance.

Implements

_MethodBase.GetParameters

The following example uses the GetParameters method to retrieve the parameters of the Invoke method of a delegate.

The example defines a delegate named MyDelegate and an event named ev of type MyDelegate. The code in the Main method discovers the event signature by getting the delegate type of the event, getting the Invoke method of the delegate type, and then retrieving and displaying the parameters.


' The following example uses instances of classes in 
' the System.Reflection namespace to discover an event argument type.
Imports System
Imports System.Reflection
Imports Microsoft.VisualBasic

Public Delegate Sub MyDelegate(ByVal i As Integer)
Public Class MainClass
    Public Event ev As MyDelegate

    Public Shared Sub Main()
        Dim delegateType As Type = GetType(MainClass).GetEvent("ev").EventHandlerType
        Dim invoke As MethodInfo = delegateType.GetMethod("Invoke")
        Dim pars As ParameterInfo() = invoke.GetParameters()
        Dim p As ParameterInfo
        For Each p In pars
            Console.WriteLine(p.ParameterType)
        Next p
    End Sub 'Main
End Class 'MainClass
