    copied!<p>I've been working on a WiX project for some time, and consuming the registry values that my setup initializes has proven to be "interesting". I am looking for a sanity check here, please.</p> <p>I have the following line in my WiX script that creates a registry value:</p> <pre><code>&lt;RegistryValue Type="multiString" Name="polling_manifest" Value="" /&gt; </code></pre> <p>This creates a registry value with the data that looks like this (from regedit/export):</p> <pre><code>"polling_manifest"=hex(7):00,00,00,00 </code></pre> <p>which, to me, looks like a string[2] with two null strings in it. In actuality, if you open this registry value with something like:</p> <pre><code> public static string[] pollingManifestValue { get { return (string[])RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry64) .OpenSubKey(AppSettingsGet("RegPathKeyConary")) .GetValue(AppSettingsGet("rTISRegKeyPollingManifest")); } set { RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry64) .OpenSubKey(AppSettingsGet("RegPathKeyConary"), true) .SetValue(AppSettingsGet("rTISRegKeyPollingManifest"), value); } } </code></pre> <p>pollingManifestValue comes back as null. Consequently, all my code that accesses this construct has to have the "check for null first, then access properties"-type code.</p> <p>I understand that those checks are the right thing to do, and I am not looking to be a more lazy programmer here. I am looking for thoughts and suggestions of those more experienced than I with the WiX deep magic, because it feels to me like I am not doing it optimally. Any code review / usage guidance is most welcome, and I thank you in advance.</p>
