Accessing Registry .NET Compact Framework v1.0

Question

Hello, I'm feeling really stupid here.  I am writing a mobile app that has to use the .NET Compact Framework v1.0.  I need to read and write some registry keys.  Simple!  There are plenty of examples to copy.  But I can't even get something using RegistryKey to compile.  I have a reference to mscorlib and say "using Microsoft.Win32", but see the following error: "The type or namespace name 'Microsoft' could not be found (are you missing a using directive or an assembly reference?)" (This is C# and Visual Studio 2005.)  Must be doing something trivial wrong?

Answer 1

Hi,

The Microsoft.Win32.RegistryKey is not present in .NET CF v1.0, as stated in the following MSDN page :-

http://msdn.microsoft.com/en-us/library/microsoft.win32.registrykey.aspx

You may be interested in the OpenNETCF.Win32 namespace which is part of the SDF :-

http://opennetcf.com/CompactFramework/Products/SmartDeviceFramework/tabid/65/Default.aspx

You may need to use one of the previous versions (1.4) as I am unsure whether the latest versions can be used with .NET CF v1.0.

Hope this helps.

Answer 2

Thanks for your help again Paul.  Is this the only way of accessing the registry in .NET CF v1.0?

Answer 3

Hi,

You can P/Invoke the appropriate native methods however it would be simplier to use the SDF.

Hope this helps.
