.NET Forum / Visual Studio.NET / Extensibility / May 2007CodeProperties2 on CSharp
Yes, that's right. I just examined the same. There is a difference between VisualBasic and CSharp: where VisualBasic will deliver any CodeProperties as CodeProperties2 CSharp did not. If you are only interested in the ReadWrite Property than you could easily check the Getter / Setter Property on the CodeProperty interface to figure out whether a get-/set- method exists or not. Obviously there are many more differences between the CSharp and the VisualBasic implementation in the VisualStudio automation which makes writing a wizard for both languages error-prone and having multiple trial-n-error iterations..... Hope that will be fixed sometime ?! cheers andi On 26 May, 14:00, andi.reid...@googlemail.com wrote: > Yes, that's right.

So you have to set try-catches to figure out the kind of the property.....(nice stuff :( ). On VisualBasic you will also get an exception for the Getter - even a get-Property method exists..... so: better to forget that way ! After some examinations I came up with the following solution: /// <summary> /// returns the kind of the property by examine the ReadWrite in case of CodeProperty2 or /// checking the access for getter / setter in case of CodeProperty /// </summary> /// <param name="propSID">the property that should be checked</ param> /// <returns>the property kind - that is: read-only, write- only or read-write</returns> public vsCMPropertyKind ExaminePropertyKind ( CodeProperty propSID ) { vsCMPropertyKind propKind = vsCMPropertyKind.vsCMPropertyKindReadWrite; if ( propSID is CodeProperty2 ) { propKind = ( propSID as CodeProperty2 ).ReadWrite; } else { try { if ( propSID.Getter == null ) { propKind = vsCMPropertyKind.vsCMPropertyKindWriteOnly; } } catch ( Exception ) { propKind = vsCMPropertyKind.vsCMPropertyKindWriteOnly; } try { if ( propSID.Setter == null ) { propKind = vsCMPropertyKind.vsCMPropertyKindReadOnly; } } catch ( Exception ) { propKind = vsCMPropertyKind.vsCMPropertyKindReadOnly; } } return propKind; } That method works for VisualBasic by checking the ReadWrite property (via the interface CodeProperty2) and CSharp by checking the access to the Getter / Setter methods. andi After some examinations I came up with the following solution: /// <summary> /// returns the kind of the property by examine the ReadWrite in case of CodeProperty2 or /// checking the access for getter / setter in case of CodeProperty /// </summary> /// <param name="propSID">the property that should be checked</ param> /// <returns>the property kind - that is: read-only, write- only or read-write</returns> public vsCMPropertyKind ExaminePropertyKind ( CodeProperty propSID ) { vsCMPropertyKind propKind = vsCMPropertyKind.vsCMPropertyKindReadWrite; if ( propSID is CodeProperty2 ) { propKind = ( propSID as CodeProperty2 ).ReadWrite; } else { try { if ( propSID.Getter == null ) { propKind = vsCMPropertyKind.vsCMPropertyKindWriteOnly; } } catch ( Exception ) { propKind = vsCMPropertyKind.vsCMPropertyKindWriteOnly; } try { if ( propSID.Setter == null ) { propKind = vsCMPropertyKind.vsCMPropertyKindReadOnly; } } catch ( Exception ) { propKind = vsCMPropertyKind.vsCMPropertyKindReadOnly; } } return propKind; } That method works for VisualBasic by checking the ReadWrite property (via the interface CodeProperty2) and CSharp by checking the access to the Getter / Setter methods. andi After some examinations I came up with the following solution: /// <summary> /// returns the kind of the property by examine the ReadWrite in case of CodeProperty2 or /// checking the access for getter / setter in case of CodeProperty /// </summary> /// <param name="propSID">the property that should be checked</ param> /// <returns>the property kind - that is: read-only, write- only or read-write</returns> public vsCMPropertyKind ExaminePropertyKind ( CodeProperty propSID ) { vsCMPropertyKind propKind = vsCMPropertyKind.vsCMPropertyKindReadWrite; if ( propSID is CodeProperty2 ) { propKind = ( propSID as CodeProperty2 ).ReadWrite; } else { try { if ( propSID.Getter == null ) { propKind = vsCMPropertyKind.vsCMPropertyKindWriteOnly; } } catch ( Exception ) { propKind = vsCMPropertyKind.vsCMPropertyKindWriteOnly; } try { if ( propSID.Setter == null ) { propKind = vsCMPropertyKind.vsCMPropertyKindReadOnly; } } catch ( Exception ) { propKind = vsCMPropertyKind.vsCMPropertyKindReadOnly; } } return propKind; } That method works for VisualBasic by checking the ReadWrite property (via the interface CodeProperty2) and CSharp by checking the access to the Getter / Setter methods. andi Free MagazinesGet these publications absolutely FREE for up to 12 months.
