VAB - IValidatorDescr iptor is inaccessible due to protection level

[Jay]

In both of the UnitTest projects that ship with the Ent Lib, (VSTS and
Nunit), there is a TestMethod with the name:
AttributeWithLo werAndUpperBoun dsOnlyCreatesAp propriateValida tor.

Each of these tests creates a StringLengthVal idatorAttribute :
ValidatorAttrib ute attribute = new StringLengthVal idatorAttribute (10,
20);

The next line creates a validator object based on the settings defined
in the Attribute:
Validator validator =
((IValidatorDes criptor)attribu te).CreateValid ator(null, null, null);

The final step prior to being able to access the properties of the
StringLengthVal idator is:
StringLengthVal idator stringLengthVal idator = validator as
StringLengthVal idator;

The following is what I have completed in my UnitTest class. The
concept of my Unit Test is to loop through all properties defined in
my Entity class, and then through the Attributes defined for each
property.

Sample:

foreach (PropertyInfo myInfo in myType.GetPrope rties())
{
foreach (Attribute attribute in myInfo.GetCusto mAttributes(tru e))
{
if (attribute is
MSValidation.Va lidators.String LengthValidator Attribute)
{
Validator validator = ((IValidatorDes criptor)
(ValidatorAttri bute)attribute) .CreateValidato r(null, null, null);
Assert.IsNotNul l(validator);

StringLengthVal idator stringLengthVal idator = validator as
StringLengthVal idator;
Assert.IsNotNul l(stringLengthV alidator);
}
}
}

The issue is that I am getting a compile error of:

Microsoft.Pract ices.Enterprise Library.Validat ion.IValidatorD escriptor'
is inaccessible due to its protection level
D:\Development\ UnitTest\Entity \CustomerUnitTe st.cs

As expected, the IValidatorDescr iptor is not color-coded in my unit
test but is in the sample UnitTests. My project is referencing the
EntLib...Valida tion DLL but I am obviously missing something. Can you
help?

Thanks

If I'm not mistaking the EntLib dll's have a [InternalsVisibl eTo]
Attribute which allows specific assemblies (including the provided test
assemblies) to see the internal variables.

Attribute which allows specific assemblies (including the provided test
assemblies) to see the internal variables.

I was looking at that attribute. However, isn't the attribute used in
the configuration of the source DLL and specifying the target assembly
that is permitted to use the Internals?

Meaning that in this scenario wouldn't I have to add that line
AssemblyInfo.cs file of the Enterprise Library object and permit my
object's access to the Enterprise Library methods?

Sorry, I'm new to the VAB and am trying to soak in as much as I can.

Thanks for your help,

Update...I managed to get this working.

I opened the actual VAB c# project ("D:\EntLib3Src \App Blocks\Src
\Validation\Val idation.csproj" ) and modified the AssemblyInfo.cs file
within this project to include the line:

[assembly: InternalsVisibl eTo("SourceAppl ication.UnitTes t")]

The SourceApplicati on.UnitTest is the namespace of my unit testing
project.

After re-compiling the application, I have taken the updated
"Microsoft.Prac tices.Enterpris eLibrary.Valida tion.dll" file and then
updated the reference to this DLL in my application. Presto! the
IValidatorDescr iptor is now accessible and can convert the attribute
into a valid Validator.

Thanks all for the help.

That is correct. So it isn't going to work with the default
pre-compiled, pre-signed assemblies.

Don't worry.

You're welcome :)
