C# Type GetConstructor(BindingFlags, Binder, CallingConventions, Type[], ParameterModifier[])

Description

Type GetConstructor(BindingFlags, Binder, CallingConventions, Type[], ParameterModifier[])searches for a constructor whose parameters match the specified argument types and modifiers, using the specified binding constraints and the specified calling convention.

Syntax

Type.GetConstructor(BindingFlags, Binder, CallingConventions, Type[], ParameterModifier[]) has the following syntax.


[ComVisibleAttribute(true)]/*from  w ww.  jav a2 s.  c o m*/
public ConstructorInfo GetConstructor(
  BindingFlags bindingAttr,
  Binder binder,
  CallingConventions callConvention,
  Type[] types,
  ParameterModifier[] modifiers
)

Returns

Type.GetConstructor(BindingFlags, Binder, CallingConventions, Type[], ParameterModifier[]) method returns An object representing the constructor that matches the specified requirements, if found; otherwise, null.

Example

The following example obtains the type of MyClass1, gets the ConstructorInfo object that matches the specified binding flags, and displays the constructor signature.


using System;/*from  ww w.  j  a  v a2  s . c o m*/
using System.Reflection;
using System.Security;

public class MyClass1
{
    public MyClass1(int i){}
    public static void Main()
    {
            Type  myType = typeof(MyClass1);
            Type[] types = new Type[1];
            types[0] = typeof(int);
            ConstructorInfo constructorInfoObj = myType.GetConstructor(
                BindingFlags.Instance | BindingFlags.Public, null,
                CallingConventions.HasThis, types, null);
            if(constructorInfoObj != null)
            {
                Console.WriteLine(constructorInfoObj.ToString());
            }
            else
            {
                Console.WriteLine("The constructor of MyClass1 that is a public instance " +
                    "method and takes an integer as a parameter is not available.");
            }
    }
}

The code above generates the following result.
