查看實體框架5.0中的查詢執行Visual Studio 2013

Question

我更新實體框架（5.0）。我正在使用Linq Method語法來查詢數據庫中的數據。我希望看到在查詢Execution.How時預先加載和延遲加載的區別我可以看到，在Visual Studio 2013年

Answer 1

public async Task<ActionResult> Details(int? id) 
{ 
if (id == null) 
{ 
    return new HttpStatusCodeResult(HttpStatusCode.BadRequest); 
} 

// Commenting out original code to show how to use a raw SQL query. 
//Department department = await db.Departments.FindAsync(id); 

// Create and execute raw SQL query. 
string query = "SELECT * FROM Department WHERE DepartmentID = @p0"; 
Department department = await db.Departments.SqlQuery(query, id).SingleOrDefaultAsync(); 

if (department == null) 
{ 
    return HttpNotFound(); 
} 
return View(department); 

}
