如何为此制作通用方法？ [英] How to make a Generic method for this?

问题描述

 public static int Insert(Model.ItemMaster entity) {
    using (Model.Entities ae1 = new Model.Entities())
    {
        ae1.Set(typeof(Model.ItemMaster)).Add(entity);
        return  ae1.SaveChanges();
            
    }
            
}

鉴于上面的代码，我想抽象这个插入方法。  但是我不想传递Model.ItemMaster类型的特定类作为实体，我想传入从使用EF5.0导入的任何表中生成的任何类。 
我该如何抽象？

Given the code above I am wanting to abstract this insert method.  But I don't want to pass in a specific class of type Model.ItemMaster as the entity, I want to pass in any class that was generated from any of the tables I imported using EF5.0.  How would I abstract that?

推荐答案

请参阅以下代码段。您还可以应用存储库模式并创建一个通用类来执行CRUD操作。请参阅我的博客链接。

Please see the following code snippet. You can also apply the Repository pattern and make a generic class to perform CRUD operations. Please see my blog link as well. http://ovaismehboob.wordpress.com/2012/10/13/implementing-repository-pattern-with-entity-framework-code-first-model-approach/

public static int Insert<T>(T TObject) where T : class
{
   Model.Entities ae1=new Model.Entities();   
   var newEntry = ae1.Set<T>().Add(TObject);
   return ae1.SaveChanges();
}
