Question

is it possible inject static property, like I do below, because it does not work for me?

    public static IMerchantModule MerchantModule { get; set; }

    public RequestBaseValidationRules()
    {
        MerchantModule = ObjectFactory.GetInstance<IMerchantModule>();
    }

It works when I inject to non static property.

Any tip welcome. Thanks, X.

Update: MerchantModule is null when it is accessed, see the example below

    public static IBusinessRule<T> Sha1HashChecksum
    {
        get
        {
            return new BusinessRule<T>(
                MethodBase.GetCurrentMethod().Name, "Sha1Hash is not valid",
                request =>
                    {
                        string sharedSecret =
                            MerchantModule.GetSharedSecretForMerchantId(request.MerchantId);
                        string hashCheck = HashHelper.GetSha1Hash(request.StringToHash, sharedSecret);
                        return request.Sha1Hash.Equals(hashCheck);
                    });
        }
    }

No, there is no problem with storing a value returned from StructureMap into a static property.

In your example, you are setting the MerchantModule property in an instance constructor, but then referencing it from a static property (Sha1HashChecksum). If you haven t yet created an instance of your class (which executes the instance constructor), the MerchantModule property will be null. Either change your code to use instance methods/properties, or set the static MerchantModule property in a static constructor (replace the word "public" with "static" in your constructor declaration).
