New Post: Windows App Certification Kit - FAIL

uesleilima — Tue, 14 May 2013 14:20:55 GMT

Trying to test my app certification, it has failed. The following error has come:

Debug configuration
Error Found: The debug configuration test detected the following errors:
The binary KellermanSoftware.Compare-NET-Objects.dll is built in debug mode.
Impact if not fixed: Windows Store doesn’t allow a debug version of an app.
How to fix: Please make sure the app isn’t linking to any debug versions of a framework, and it is built with release configuration. If this is a managed app please make sure you have installed the correct version of .NET framework.

Please download the latest version and re-send the stack trace. The line numbers do not match. I am not sure what is going on.

Rex,

By default, it should only show the first difference. See the MaxDifferences property.

Thanks,

New Post: Dilemma over the usage of AttributesToIgnore.Add()

JoeHax — Fri, 26 Apr 2013 01:33:13 GMT

@swainjena

Not sure if you figured this out yet, but if you take a look at Greg's Unit Tests you can figure out how to use the attributes. Specifically:

Attribute class setup

Decoration of a Property

Leveraging its usage in a comparison (IgnorePropertyAttribute method)

@Greg

Great code, very useful; thanks for sharing with the community.

Thank you. It will be quite a while before this issue can be looked into.

New Post: Culture exception when comparing objects

tequilacat — Tue, 19 Mar 2013 11:36:32 GMT

The usage is very simple, I compare 2 objects having properties representing lists of sub-objects etc using VisualStudio generated unit test project.

CompareObjects compareObjects = new CompareObjects();
Assert.IsTrue(compareObjects.Compare(p,np));

The error details:

Error message:

Test method TestProject1.ProjectTest.TestProjectPersistenceXml threw exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.NotSupportedException: Culture 'fr' is a neutral culture. It cannot be used in formatting and parsing and therefore cannot be set as the thread's current culture..

New Post: Culture exception when comparing objects

tequilacat — Tue, 19 Mar 2013 07:08:34 GMT

Hi

I try to compare the 2 objects and get the exception that "the current culture "fr" is neutral and cannot be set as thrread current".
It's thrown deep in the C# System code , called from info.GetValue(object1, null) called from CompareObjects.PerformCompareProperties
I tried to set specific thread cultures before test, like en-US or fr-FR, all in vain.

Is there some specific way of test configuration to run in culture independent environment? Can it depend on kind of compared objects?
Or is there some generic C# knowledge I miss here like problems when adding the 3rd party tool dll's to my project, etc.

Thanks in advance
Alex

New Post: Compare returns all properties in list as different when they are not.

rexdefuror — Mon, 11 Mar 2013 10:08:03 GMT

I pass two lists of objects:

public class FieldData
{
    public Identifier FieldID { get; set; }
    public string Value { get; set; }
    public int SectionNumber { get; set; }
}

Each lists consist of 173 objects that are generally identical unless something on the form changed. So I change that one thing it should return only that one change, and not full list of 173, as it does now.

var compare_objects = new CompareObjects();
compare_objects.Compare(source_object.Fields, target_object.Fields);

Anything I'm doing wrong?

New Post: Not possible of reading config file

KoenVanHoeck — Tue, 29 Jan 2013 15:47:36 GMT

gfinzer,

I fixed the problem by setting all the setting values to 'Application' instead of 'User'. That was 1 :-)

I did other changes in SetupWithSettings (some code missing) and CompareIndexer (will not work if first list has less objects than the second list).

New Post: Not possible of reading config file

KoenVanHoeck — Mon, 28 Jan 2013 07:10:09 GMT

gfinzer,

That is just my whole point. I cannot use the NuGet implementation because it does not use the config file.

Even with your solution (which I already did) the solution will not work because IsUseCustomTypeComparer is null.

A better solution is to always configure CompareNETObjects without configuration file, and after that, read the config file and overwrite local defaults when specified in the config file. That is how I changed the code here in our project. Something like this:

	private void SetupWithSettings()
        {
	    SetupWithoutReadingSettings();
 
            if (ConfigurationManager.AppSettings["MaxDifferences"] != null)
            {
                int maxDifferences;
                if (Int32.TryParse(ConfigurationManager.AppSettings["MaxDifferences"].ToString(), out maxDifferences))
                    MaxDifferences = maxDifferences;
            }
        }

Isn't this a better solution? In this case everyone can use the NuGet implementation with or without having a config file.

Tia,

Koen

Koen,

You can use a config file. Simply get the source and define

//#define USE_SETTINGS

Thanks,

New Post: Not possible of reading config file

KoenVanHoeck — Fri, 25 Jan 2013 13:47:10 GMT

Hi,

When i use dotPeek to see the NuGet package provides, I see this:

public CompareObjects() {

this.Differences = new List<Difference>();

this.AttributesToIgnore = new List<Type>();

this.CustomComparer = (Action<CompareObjects, object, object, string>) null;

this.SetupWithoutReadingSettings();

}

Is is not possible to configure CompareNETObjects with a config file? I just want to adjust MaxDifferences, because 1 is to low.

I want to do this once, for all CompareObjects made in my project, not in code, and I don't want to use a personal build. If there is no override of the property in the config file, the default value must be used.

At the moment I have fixed it by referencing my own build of CompareNetObjects.

Tia,

Koen

RachanaDikshit — Wed, 15 Aug 2012 16:41:11 GMT

Hello,

I need to cpmpare 2 xml's that have many differences. I am using the dll, but it shows me just the first difference. What do I need to do to be able to see all the difference?

My requirement is to comapre the 2 xml's generated from the same xsd and show the differences in the format like Example: ADD Address; Update DOB; Delete Make. etc

StringReader stream = null;
            XmlTextReader reader = null;
            StringReader stream1 = null;
            XmlTextReader reader1 = null;
            String xml = "C:\\Basic\\SP\\Trial1.xml";
            String xml1 = "C:\\Basic\\SP\\Trial2.xml";
            String docTXT = File.ReadAllText(xml);
            String docTXT1 = File.ReadAllText(xml1);
            // serialise to object
            XmlSerializer serializer = new XmlSerializer(typeof(fullRecordDetails));
            stream = new StringReader(docTXT); // read xml data
            reader = new XmlTextReader(stream); // create reader

            stream1 = new StringReader(docTXT1); // read xml data
            reader1 = new XmlTextReader(stream1); // create reader
            // covert reader to object

fullRecordDetails detail1 = (fullRecordDetails)serializer.Deserialize(reader);
fullRecordDetails detail2 = (fullRecordDetails)serializer.Deserialize(reader1);

            string differenceString=null;
            CompareObjects compareObjects = new CompareObjects();
            if (!compareObjects.Compare(detail1, detail2))
                differenceString = compareObjects.DifferencesString;
