Fail to read simple string from the registry ( code attached )

[Lost User]

Try to read string from the registry - i get beck null all the time Code:

public static string ReadStringFromRegistry( string hive, string key )
{
string strRetVal = null;

        try
        {

            using( RegistryKey regKey = Registry.LocalMachine.OpenSubKey( hive ) )
            {
                if( null != regKey )
                {
                    strRetVal = regKey.GetValue( key ) as string;

                    if( String.IsNullOrEmpty( strRetVal ) )
                    {
                        strRetVal = null;
                        Debug.Assert( false, "fail to read from the registry" );
                    }
                }
            }
        }
        catch( Exception e )
        {

        }

        
        return strRetVal;
    }

Your code is working fine for me, so there is nothing wrong with it. You probably have wrong input strings. Please check if "hive" and "key" are correct.

Thanks, In the line strRetVal = regKey.GetValue( key ) as string; i get strRetVal as null.

So, what is the value that you expect to read? And of which type is it?

You can also see this site that explains how to use the .GetValue() method with different registry value types: http://msdn.microsoft.com/en-us/library/fdf576x1%28VS.80%29.aspx[^]

I read simple string that i created. If i try to read some other string ( that i did not created ) from the next hive - i see that the result are ok. Very Strange... P.S: using win7 - and i check the premmision of the registry access.

Have you checked in the registry editor if your created string is somehow different from the one you are able to read? (is it of type REG_SZ?) I just tested creating one key and then read it back and it worked fine with XP.

when you swallow exceptions like you do, you deserve the trouble you're getting. X|
