I have created methods for converting a property lambda to a delegate:
public
static Delegate MakeGetter<T>(Expression<Func<T>> propertyLambda)
{
var result = Expression.Lambda(propertyLambda.Body).Compile();
return result;
}
public
static Delegate MakeSetter<T>(Expression<Action<T>> propertyLambda)
{
var result = Expression.Lambda(propertyLambda.Body).Compile();
return result;
}
These work:
Delegate getter = MakeGetter(() => SomeClass.SomeProperty);
object o = getter.DynamicInvoke();
Delegate getter = MakeGetter(() => someObject.SomeProperty);
object o = getter.DynamicInvoke();
but these won't compile:
Delegate setter = MakeSetter(() => SomeClass.SomeProperty);
setter.DynamicInvoke(new object[]{propValue});
Delegate setter = MakeSetter(() => someObject.SomeProperty);
setter.DynamicInvoke(new object[]{propValue});
The MakeSetter lines fail with "The type arguments cannot be inferred from the usage. Try specifying the type arguments explicitly."
Is what I'm trying to do possible? Thanks in advance.
