How to retrieve component by specific Schema?

How to resolve it?

You can get a list of components wich uses that schema by this TOM.NET code:

UsingItemsFilter filter = new UsingItemsFilter(schema.Session);
filter.ItemTypes = new List<ItemType> { ItemType.Component };
filter.IncludedVersions = VersionCondition.OnlyLatestVersions;

IEnumerable<IdentifiableObject> components = schema.GetUsingItems(filter);

Then, for each component of the returned list you can retrieve the propertiy "RevisionDate".

Also you cas use Tridion CoreService to obtain the list of components based on that schema:

SearchQueryData query = new SearchQueryData() {
    BasedOnSchemas = new BasedOnSchemaData[] { 
        new BasedOnSchemaData(){ 
            Schema = new LinkToSchemaData(){ IdRef= "{schemaId}" }
        }
    },
    SearchIn = new LinkToIdentifiableObjectData() { IdRef = "{publicationId}" }, 
    ItemTypes = new ItemType[]{ ItemType.Component }
};

XElement xResults = channel.GetSearchResultsXml(query);

This is from this post: How to get all Components based on a Schema and from a particular Publication?

Hope it helps.
