One request to share an instance (value) to store (instance) values in the current request thread area

There is a dbcontext context in EF, and if each access to the database produces a dbcontext that's a bad idea, it's a good practice to have a dbcontext instance once in a single request, and you can store dbcontext to the current request thread area.

The test uses the current request thread store code:

1 usingSystem;2 usingSystem.Collections.Generic;3 usingSystem.Linq;4 usingSystem.Text;5 6 namespaceRuntimedemo7 {8     /// <summary>9     ///to test the storage of thread valuesTen     /// </summary> One     class Program A     { -         Static voidMain (string[] args) -         { theSystem.Runtime.Remoting.Messaging.CallContext.SetData ("Valuekey","value stored in the current request thread area");//storing values in the current request thread area stores the values in the current thread area to be recovered by the sleeping thread being recycled -  -             stringstr = System.Runtime.Remoting.Messaging.CallContext.GetData ("Valuekey") as string;//gets the value stored in the thread area of the current request -  + Console.WriteLine (str); -  + console.readline (); A  at         } -     } -}

The above code runs the result:
