how to cast string to generic type

Question

I've class name which is in string format,I need to execute dynamically function and cast result into dynamically

    Type type = Type.GetType(method.NameSpace + "." + method.ClassName, false);
    //

      Type calledType = Type.GetType(namespaceName + "." + className + "," + assemblyName);
             //this function return object type of class type which is I've created from string className      
var result=  calledType.InvokeMember(
                                methodName,
                                BindingFlags.InvokeMethod | BindingFlags.Public | BindingFlags.Static,
                                null,
                                null,
                                obj);

OR AlTERNAtely

public T CAST<T>(Object o){
//some mechanism
}

CAST<type >(result);

gives type or namespace name expected .. How do I Cast dynamically generated class type to generic type

Now I need to cast var result to a Type type (dynamic class). How?

I think what you need is Convert.ChangeType . Below is a samples for invoking MyMethod with string[] parameters.

public static string MyMethod(string s, int i, DateTime d)
{
    return s + " " + i + " " + d.ToString();
}

public T Execute<T>()
{
    //They are all strings in object array
    object[] myparams = new object[] {"test","3","04/03/2012" };

    Type[] types = this.GetType()
                       .GetMethod("MyMethod")
                       .GetParameters()
                       .Select(p=>p.ParameterType)
                       .ToArray();

    object result = 
        this.GetType().InvokeMember(
        "MyMethod",
        BindingFlags.InvokeMethod | BindingFlags.Public | BindingFlags.Static,
        null,
        this,
        myparams.Select((s,i)=>Convert.ChangeType(s,types[i])).ToArray()
        );

    return (T)result;
}
