Why error is there

[lokiys]

Why I'm sometimes getting error from this code:

var r = new Random();
int rand = r.Next(1, 12);
System.Threading.Thread.Sleep(1000);
if(rand == 1) project.Profile.Login = project.Profile.Surname + project.Profile.Age;
else if(rand == 2) project.Profile.Login = project.Profile.Login;
else if(rand == 3) project.Profile.Login = project.Profile.Name + project.Profile.Age + project.Profile.Surname;
else if(rand == 4) project.Profile.Login = project.Profile.Name + "." + project.Profile.Surname;
else if(rand == 5) project.Profile.Login = project.Profile.Name + project.Profile.Surname + project.Profile.Age;
else if(rand == 6) project.Profile.Login = project.Profile.CurrentRegion + project.Profile.Age;
else if(rand == 7) project.Profile.Login = project.Profile.Interest + project.Profile.Age;
else if(rand == 8) project.Profile.Login = project.Profile.NickName;
else if(rand == 9) project.Profile.Login = project.Profile.Name + project.Profile.ZipCode;
else if(rand == 10) project.Profile.Login = project.Profile.Name + project.Profile.BornYear;
else if(rand == 11) project.Profile.Login = project.Profile.Surname + project.Profile.BornYear;

Error message: Object reference not set to an instance of an object.

Yes works also for me fine in PM - at least never got error, but when i run it in ZP then sometimes I'm getting this error, this is why I'm wondering what is problem with code or there is bug...

Profile.Interest ?

Profile.Interest ?

Looks like really this will make error, but check there is such string in c#. You can define project.Profile.Interest but when you try to execute then there is this error Object reference not set to an instance of an object.

Means that need to delete it from possible options...
