Name of the constructor arguments in c#

I've a requirement in which i need to get the variables names of the constructor in my class. I tried it using c# reflection, but constructorinfo does not give sufficient information. As it only provides the datatype of the parameters but i want the names, ex

class a
{    
    public a(int iArg, string strArg)
    {
    }
}

Now i want "iArg" and "strArg"

Thanks
