Question

Today I came across a problem I had never had before. I’m trying to check if a file exists from a value in Windows registry. To be more specific, I’m getting the installation path from Flight Simulator and checking if there is a module installed.

I get the registry key just fine and it is converted to a string (from an object) but I don’t seem to be able to concatenate the filename after it (before is just fine).

RegistryKey pRegKey = Registry.CurrentUser;
pRegKey = pRegKey.OpenSubKey(@"Software\Microsoft\Microsoft Games\Flight Simulator\10.0");
string fSPath = pRegKey.GetValue("AppPath").ToString(); // Receives "S:/Apps/FSX/"

If I show a messagebox like this it does not concatenate:

MessageBox.Show(fSPath + "Modules");

Answer 1

Add the following line:

string fSPath = fsPath.Replace("\0","");

before using messagebox.
