Question

Assume the class is public and and the constructor is internal like as

Public class A
{
    private string text;

    internal A(string submittedText);

    public string StrText { get; }
}

In this case how could I Access the constructor by using Reflection. What I have done so far

Type[] pTypes = new Type[1];

pTypes[0] = typeof(object);

object[] argList = new object[1];

argList[0] = "Some Text";


ConstructorInfo c = typeof(A).GetConstructor
                (BindingFlags.NonPublic |
                 BindingFlags.Instance,
                 null,
                 pTypes,
                 null);


A foo = (A)c.Invoke(BindingFlags.NonPublic,
                    null,
                    argList,
                    Application.CurrentCulture);

But it shows an error. Any Suggestions

I think the error might casued by the GetConstructor, you passed in Object type instead of String type.

var ctr = typeof(A).GetConstructor(BindingFlags.Instance | BindingFlags.NonPublic, null, new Type[] { typeof(String) }, null);

btw, if the type A itself is internal, and you know public Type B and A in the same assembly, you can try:

Type typeA = typeof(B).Assembly.GetType("Namespace.AssemblyName.A", false);
var ctr = typeA.GetConstructor(BindingFlags.Instance | BindingFlags.NonPublic, null, new Type[] { typeof(String) }, null);
