Class DynamicElementAccess
An element access where the qualifier is a dynamic
expression, for example
d[0]
on line 12 in
class A {
public A() { }
public int this[int i] { get { return i + 1; } }
}
class B {
string[] Array = new[] { "a", "b", "c" };
public dynamic GetItem(bool b) {
dynamic d = b ? new A() : (dynamic) Array;
return d[0];
}
}
Unlike an ordinary element access (ElementAccess
), the type of the member
being accessed may not be known at compile-time (it can be either an indexer
or an array).
