Program Version Number

[Bill Cart]

We are using c# windows forms and just trying to get started with .net. I
want to do something that should be easy but I can't find any way to make it
work. We are using Click Once to publish to a network drive and I need to be
able to check if a program is the current version. Because the users can
choose to not download the latest version this may be a problem. I just want
to show what version they are running.

I found some code that gave me:

private void FrmMain_Load(ob ject sender, EventArgs e)
{
FileVersionInfo fvi =
FileVersionInfo .GetVersionInfo (Application.Ex ecutablePath);
string version = fvi.FileVersion .ToString();
MessageBox.Show (version);
}

I am not sure if this will give me what I need. And it also gets an error I
don't understand. Why would gettting the version number be a security
exception?

System.Security .SecurityExcept ion was unhandled
Message="Reques t failed."
Source="AfterSc hool1"

For ClickOnce, that won't give the current version number... instead (from a
post by Andrej Tozon):

if (System.Deploym ent.Application .ApplicationDep loyment.IsNetwo rkDeployed)
{
Version version =
System.Deployme nt.Application. ApplicationDepl oyment.CurrentD eployment.Curre ntVersion;
string versionString = version.ToStrin g();
}

I tried the System.Deployme nt method
System.Deployme nt.Application. ApplicationDepl oyment ad1 =
System.Deployme nt.Application. ApplicationDepl oyment.CurrentD eployment;
System.Windows. Forms.MessageBo x.Show(ad1.Curr entVersion.ToSt ring());

but when I test it I get the following error:

System.Deployme nt.Application. InvalidDeployme ntException was unhandled
Message="Applic ation is not installed."
Source="System. Deployment"

I just found out the it only does this in the debuger so I guess that makes
sense, it really is not deployed yet.
