Hello Qian,
Hi All,
I want to print some object information for debugging. But the name of
class is incorrect. I do not know why.
module test;
class A {
char[] data;
public char[] toString() {
return "<" + this.classinfo.name + ": " + data + ">";
}
}
class B: A {
char[] data2;
public override char[] toString() {
return "<" + this.classinfo.name + ": " + super.toString + ", " +
data2
+ ">";
}
}
auto b = new B;
b.data = "hello";
b.data2 = "world";
Cout(b.toString); // <test.B: <test.B: hello>, world>
The expected result should be:
<test.B: <test.A: hello>, world>
But the actual result is:
<test.B: <test.B: hello>, world>
use typeof(this).classinfo.name to get type of A. "this" returns runtime
type of instance, "typeof(this)" return static type.

btw. I noticed that you are using "+" for string concatenation, how is possible
that your program even comiples??? "~" should be used for string concatenation.
