That's because in the direct array access code, the structs are being
directly modified. In
The problem is a restriction on the foreach construct: it doesn't allow
modifications to the elements you are iterating on, see [1].
Interestingly, if you define Foo as a class instead of a struct then Foo
[0].Bar can be modified and has the correct "bar" value after the loop. If
Foo is an struct
Jim,
I was able to get the last example to compile with the following
modification:
Foo[] foos = new Foo[1];
foos[0] = new Foo();
foreach(Object obj in foos) {
Foo foo = (Foo) obj;
foo.Bar = "bar";
}
//but foos[0].Bar is still "" here...
Note that difference is that the type of t

struct Foo {
string _bar;
public string Bar {
get{return _bar;}
set{_bar = value;}
}
}
Why can I do this:
Foo foo = new Foo();
foo.Bar = "bar";
and this:
Foo[] foos = new Foo[1];
foos[0] = new
