Is it possible to see a variable with a variable hardcoded using a disassembler like Reflector?
Given the source code example below, is it possible for someone to see the value _secret
using a disassembler? I haven't seen a way to get the value through Reflector, but I haven't used it very much. Let's assume the code is not obfuscated in any way.
class Foo
{
private string _secret = @"all your base are belong to us";
public void Foo()
{
...
}
}
Thank!

It displays in the constructor in Reflector.
class Foo { private string _secret = @"all your base are belong to us"; }
translates to constructor
public Foo() { this._secret = "all your base are belong to us"; }
which is displayed in Reflector under Foo
the method .ctor
.
You can also see this information in ildasm
(comes with Microsoft Visual Studio) at Foo::.ctor : void
:
.method public hidebysig specialname rtspecialname instance void .ctor() cil managed {
// Code size 19 (0x13)
.maxstack 8
IL_0000: ldarg.0
IL_0001: ldstr "all your base are belong to us"
IL_0006: stfld string Playground.Foo::_secret
IL_000b: ldarg.0
IL_000c: call instance void [mscorlib]System.Object::.ctor()
IL_0011: nop
IL_0012: ret
} // end of method Foo::.ctor
Finally, if someone knows the name of your type and the name of your private field, you can get the value as such:
object o = typeof(Foo).GetField(
"_secret",
BindingFlags.Instance | BindingFlags.NonPublic
).GetValue(f);
Console.WriteLine(o); // writes "all your base are belong to us" to the console
Of course, I can always see all of your personal fields with
var fields = typeof(Foo).GetFields(
BindingFlags.Instance | BindingFlags.NonPublic
);
