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)

public abstract ParameterInfo[] GetParameters()

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.

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.
using System;
using System.Reflection;

public delegate void MyDelegate(int i);
public class MainClass 
{
    public event MyDelegate ev;

    public static void Main() 
    {
        Type delegateType = typeof(MainClass).GetEvent("ev").EventHandlerType;
        MethodInfo invoke = delegateType.GetMethod("Invoke");
        ParameterInfo[] pars = invoke.GetParameters();
        foreach (ParameterInfo p in pars) 
        {
            Console.WriteLine(p.ParameterType);
        }
    }
}
// The example displays the following output:
//       System.Int32
