070-516試験無料問題集「Microsoft TS: Accessing Data with Microsoft .NET Framework 4 認定」
You use Microsoft .NET Framework 4 to develop an application that connects to a Microsoft SQL Server
2008 database.
The database contains a ClassStudent table that contains the StudentID for students who are enrolled in
the classes.
You add the following stored procedure to the database.
CREATE PROCEDURE [dbo].[GetNumEnrolled] @ClassID INT, @NumEnrolled INT OUTPUT
AS BEGIN SET NOCOUNT ON SELECT @NumEnrolled = COUNT(StudentID)
FROM ClassStudent
WHERE (ClassID = @ClassID)
END
You write the following code. (Line numbers are included for reference only.)
01 private int GetNumberEnrolled(string classID)
02 {
03 using (SqlConnection conn = new SqlConnection(GetConnectionString())
04 {
05 SqlCommand cmd = new SqlCommand("GetNumEnrolled", conn);
06 cmd.CommandType = CommandType.StoredProcedure;
07 SqlParameter parClass = cmd.Parameters.Add("@ClassID", SqlDbType.Int,
4, "classID");
08 SqlParameter parNum = cmd.Parameters.Add("@NumEnrolled",
SqlDbType.Int);
09 ...
10 conn.Open()
11 ...
12 }
13 }
You need to ensure that the GetNumberEnrolled method returns the number of students who are enrolled
for a specific class.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application.
The application uses the ADO.NET Entity Framework to model entities.
You define a Category class by writing the following code segment. (Line numbers are included for
reference only.)
01 public class Category
02 {
03 public int CategoryID { get; set; }
04 public string CategoryName { get; set; }
05 public string Description { get; set; }
06 public byte[] Picture { get; set; }
07 ...
08 }
You need to add a collection named Products to the Category class. You also need to ensure that the
collection supports deferred loading.
Which code segment should you insert at line 07?

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application.
The application uses the ADO.NET Entity Framework to model entities. You create an entity as shown in
the following code fragment.
<EntityType Name="ProductCategory">
<Key>
<PropertyRef Name="ProductCategoryID" />
</Key>
<Property Name="ProductCategoryID" Type="int" Nullable="false" StoreGeneraedPattern="Identity" />
<Property Name="ParentProductCategoryID" Type="int" />
<Property Name="Name" Type="nvarchar" Nullable="false" MaxLength="50" />
...
</EntityType>
You need to provide two entity-tracking fields:
-rowguid that is automatically generated when the entity is created
-ModifiedDate that is automatically set whenever the entity is updated. Which code fragment should you add to the .edmx file?

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application.
The application connects to a Microsoft SQL Server database. The application uses the ADO.NET Entity
Framework to manage order data.
The application makes a Web service call to obtain orders from an order-tracking system.
You need to ensure that the orders are added to the local data store. Which method should you call on the
ObjectContext?
