c# - Implementing Binding Paths -

trying implement field binding system , have following method:

    public void setvalue<tfield>(expression<func<tfield>> field, object value)     {         ((field.body memberexpression).member fieldinfo).setvalue(this, value);          // check bindings etc.     } 

that used this:

    myobj.setvalue(() => myobj.somestringfield, "somestring"); 

it works intended, value set , can other stuff want checking bindings etc.

now i'm trying implement support of binding paths, i.e. allow like:

    myobj.setvalue(() => myobj.names[1].firstname, "john"); 

i got fieldinfo of firstname need (at least) reference object myobj.names[1] expression. ideas on how this?

a general approach create expression assigns value expression:

public static void setvalue<tfield>(expression<func<tfield>> field, tfield value) {     var expression = expression.lambda<action>(         expression.assign(field.body, expression.constant(value)));     expression.compile()(); }
