ToString() does not exist ... anywhere !

[John A Grandy]

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

Project was in a working state before -- it never threw any of these
exceptions.

Which exceptions? (type, message, stacktrace, code snippets please!)

QuickWatch sometimes does silly things. But it would be interesting to
see these exceptions and the code that generates them.

Well, as I mentioned above, it's things like :

using System.Data.Sql Client;

SqlConnection sqlConnection = new
SqlConnection(" server=SERVER1; database=DB1;TR USTED_CONNECTIO N=true");
sqlConnection.O pen();
if (sqlConnection. State.ToString( ) = "open")
{
....
....
}

If I QuickWatch over sqlConnection.S tate.ToString() I receive

"error: '{object name}.ToString' does not exist:"

Is there any particular reason not to use enumeration?

if(sqlConnectio n.State == ConnectionState .Open)
{
....
}

This isn't a code-design exercise. This is a huge project written by
someone else. They already used .ToString() in thousands of places,
thousands of contexts. Somehow, ToString has stopped being recognized.

I've tried de-installing, re-installing .NET Framework 1.1.4322 , to no
avail.

You can't use the Watch window on methods. It only works for fields and
properties (at least in VS2003, dunno about VS2005).

If you get real (runtime) exceptions, please post their type, message
and stacktrace.

Hi, Just wondering if you found the answer to the .Tostring problem,
Currently i am having the same problem.
If i try the same code in vb instead of c# it works fine. Appear to be
affecting c# only.

I'd love to see an answer posted for this issue too. I'm having the
exact same problem in VS2003.

Here's the line:

cmd.Parameters. Add("@DestDB", newCompany.ToSt ring() + RequestYear);

It's a very simple concat that's been working since before I started
with this company. In fact, it was working about an hour ago. The
project compiles, and I even get a "ToString" option from Intellisense,
but I still get the not recognized error at runtime.

"newCompany " is an enum type that has a verifiable value before trying
to execute this line. "RequestYea r" is a string representing a 4 digit
year.

What error do you get at runtime *not* in the debugger? I suggest we
ignore the debugger for the moment, as the VS2003 debugger in
particular had some issues.

I replied to this a while ago, but don't see it here now.

To reiterate:

I was having other runtime issues not involving this one, so I can't say
that it was strictly a debugger issue...though I believe that it was.

Here's what I did instead that worked:

string Company = System.Convert. ToString(newCom pany);
string Year = System.Convert. ToString(Reques tYear);

cmd.Parameters. Add("@DestDB", System.String.C oncat(Company + Year));

Sorry about that.

I never specified that I wanted to email you. Hopefully, you don't get
this one too.

I didn't see anything in the FAQ about it either. Did I miss something?
