Explicit Loading with DBContextEven with lazy loading disabled, it's still possible to lazily load related entities, but it must was done with an Explici T call. Use the Load method of Dbentityentry object to accomplish this.The following code explicitly loads standard of particular Student using the Reference () method of Dbentityentry:using(varContext =Newschooldbentities ()) { //Disable Lazy LoadingContext. configuration.lazyloadingenabled =false; varStudent = ( fromSinchcontext.

[Address1], [Extent1]. [Address2] As [Address2], [Extent1]. [City] As [city], [Extent1]. [State] As [State]from [dbo]. [Studentaddress] As [Extent1]where [Extent1]. [StudentID] = @EntityKeyValue1', N'@EntityKeyValue1 int',@ EntityKeyValue1=1However, you can also turn off lazy loading for a particular property or an entire context. To turn off-lazy loading for a particular property, does not make it virtual. To turn off-lazy loading for all entities in the context, set it configuration property

nodes can be placed irregularly on the surface, the TIN can have a higher resolution in areas where the surface is fluctuating or where more detail is required, whereas in areas with smaller surface fluctuations it can have a lower resolution.The input features used to create the tin are in the same position as the nodes or edges in the tin. This allows the TIN to model the values between known points while preserving all the precision of the input data. You can introduce precisely positioned f

For example:Class CTest {static void Main () {EditBox editbox = new EditBox ();EditBox. Paint (); Error: Different methodsIControl control = EditBox;Control.

Paint () is the correct way to call.Note: The inte

C ++ tutorial Chapter 2-variable Basics 1. Basic built-in types C ++ contains the arithmetic and Null Types. The arithmetic type includes characters, integer numbers, Boolean values, and floating point numbers. Char, int, long, bool, float, double, etc. Note that there is an unsigned type called the unsigned number, and the unsigned number constant is greater than 0. Note that if you execute in while: un

Now, let's look at a "mutable" tuple:>>> t = (‘a‘, ‘b‘, [‘A‘, ‘B‘])Notice that T has 3 elements: ' A ', ' B ' and a list:[' a ', ' B '. List as a whole is the 3rd element of a tuple. The list object can be obtained
