In .NET v1.1.4322 , in a VS.NET application , has anyone ever run into the
bizarre situation where at runtime .NET believes that the ToString() method
does not exist ...
Sometimes this problem will show up as a runtime exceptions, sometimes this
problem will only be clear via QuickWatch in Debug mode
But the error message is always identical :
"error: '{object name}.ToString' does not exist:"
It could be
System.Data.Sql Connection.SqlC lient.State.ToS tring()
or it could be
Application["key name"].ToString()
or a variety of other uses of the ToString() method ...
I've tried rebuilding , restarting the machine ... but the problem
continues.
This is the strangest behavior I have ever encountered

Quick checklist
Typo?
Did you remember the parens?
Bill
Well, neither of the 2 lines you are showing look valid to me; the first has
the namespace knackered, and doesn't seem to involve an instance; the second
(assuming System.Windows. Forms.Applicati on) simply doesn't have a static
indexer.
QuickWatch will allow these as lines, but they will report error - simply
because they don't exist; I'd be more interested in the runtime exceptions,
as I don't think that code can compile.
Are you sure the problem isn't the code? Perhaps calling .ToString() on some
null objects? If you can get as far as runtime, then (assuming it isn't
reflection) it knows it exists. Have you overridden the ToString() method
and screwed it up, perhaps?
Marc
Ok, this is a production project that was working fine. It somehow
"entered" a state where somehow .NET is reporting that the .ToString()
method does not exist on various classes.
ToString() is not overriden anywhere in the project.
There was a typo: I meant
System.Data.Sql Client.SqlConne ction con = new
System.Data.Sql Client.SqlConne ction();
con.State.ToStr ing();
QuickWatch on con.State.ToStr ing() gives the error "error: '{object
name}.ToString' does not exist:"
Also, this is an ASP.NET app , so the intrinsic Application object is an
instance of the HttpApplication State class
QuickWatch can be performed on Application[{key-name}] with no problem.
But QuickWatch on Application[{key-name}].ToString() gives the errror
"error: '{object name}.ToString' does not exist:"

You have to over ride ToString(). It is completely virtual. Hope that
helps.
I've never had to override ToString() before ... ever. I've seen the source
for dozens of high quality projects, and none of them includes overrides of
intrinsic ToString() methods on .NET framework classes.
Project was in a working state before -- it never threw any of these
exceptions.

I'm not 100%, but I think overriding ToString() started with VS 2005. Not
sure why some other things still work with ToString(); maybe they inherit
something else that has a built in version, but that's just a guess.
I'm on VS03 with .NET 1.1

why I can not override it?
This line: virtual String^ ToString() override = Object::ToString;

If we have something like this

MessageBox.Show(x.ToString())
we get an error. That kindof makes sense but there is no reason the
behaviour couldn't be to return an empty string. When we call x.ToString we
are really calling a function like this:
