Finally, let's look at how to use such entity classes in the project: The object class of the custom query is similar to the ordinary PDF.. Net object classes are used in a similar way. They all require oql expressions for operations. For example,

//Name = "My Oh Da", A //CompanyID = c.id, - //}; - //EF. Users.add (u); the //Ef.Companies.Add (c); - - varDF = fromUinchEF. Users - whereU.company.name = ="NX" + Selectu; - varFDDF =DF.

the default value of DateTime is "0001-01-01", when entity framework performs database operations, when the data is imported, the original datetime data field is automatically converted to the datetime2 type (because the time of 0001-01-01 is beyond the minimum date range of datetime in the database ), then, perform database operations. The problem arises. Although EF has automatically converted the data t
