When the key in the dictionary is an entity, you can use containskey to compare the results. Even if the model is the same, the results do not exist; Use the following code to convert keys to toarray () and compare them with the array contains; However, you must note that you must rewrite equals for the object class to compare a field in the object that is equal to that in the object; VaR menumodel = new dictionary Namespace model {public class menug

Preface Before going into the details of the object framework, we will first discuss the convenience of data access from the traditional dataset Method to the object-based method, and how these two methods work differently to lead to the use of O/RM tools like Entity Framework. Use dataset and datareader as data containers Let's first look at an example. Suppose there is a database with two tables: Order and orderdetail. The table structure is a

If lazy loading enable = true is not set in the Entity Framework, the handler must handle the loading of the metadata, for example, using load or include, however, because the include parameter number is string, it is very difficult for a person to find the parameter easily after tablename is changed with string, so I want to introduce an extension method. // Adventureworkslt2008r2entities context = new adventureworkslt2008r2entities (); var customer

the needs of the database, and data separation is difficult for applications to use. Designing an object model first is a top-down approach. The main advantage of top-down is that applications are almost independent from databases to shape their models. The disadvantage is that sometimes it may not be conducive to the organization of the database, and may also lose performance. Databases are an important part of applications. Therefore, model design and database design should be seamlessly c

Domain Layerentity is one of the core concepts of DDD (domain driven design). Eric Evans describes this as "a lot of objects are not defined by their attributes, but by a series of continuity events and Identity Definitions" (a reference to the domain-driven design book). Translators note that objects are not defined by their attributes, but by their linear continuity and identity. Therefore, an entity is an ID that has a unique identity and is store
