Certkiller .com has asked you to create a file management application to monitor the hosts file.
Certkiller .com has instructed you to change the hosts file if it has been changed.
You, therefore, need to display the size and whether the hosts file is set to read-only.
What should you do?（）

Certkiller .com has asked you to develop an application that displays the properties for all Certkiller.com's network drives.
The information generated by this application will be utilized by Certkiller .com's network administrators to verify client setups.
You need to ensure that these requirements are fully satisfied.
What should you do?（）

You have recently completely creating a new application for Certkiller .com.
This new application has to load an instance of the Inventory class from a large file named Inventory.dat.
You need to ensure that the application executes the loading process in as little time as possible.

you have recently written the code shown below:
Hashtable emailAddresses = new Hashtable ();
emailAddresses.Add ("Mia", "mia@ Certkiller .com");
emailAddresses.Add ("Andy", "andy@ Certkiller .com");
emailAddresses.Add ("Kara", "kara@ Certkiller .com");
You need to ensure that these e-mail addresses are stored in the Email.dat file so that you can load them again
when the user restarts the application.

You have recently written the code shown below:
Hashtable emailAddresses = new Hashtable ();
emailAddresses.Add ("Mia", "mia@ Certkiller .com");
emailAddresses.Add ("Andy", "andy@ Certkiller .com");
emailAddresses.Add ("Kara", "kara@ Certkiller .com");
FileStream stream = new FileStream ("Email.dat", FileMode.Create);
BinaryFormatter formatter = new BinaryFormatter ();
formatter.Serialize (stream, emailAddresses);
You need to ensure that you are able to load the emailAddresses object from the Email.dat file into your application.

您最近创建了一个名为车辆的可序列化的类。
类如下所示：
[Serializable]
public class Vehicle {
public string VIN;
public string Make;
private string Model;
private int Year;
private string Owner;
}
Certkiller.com 不想要序列化一个车辆对象，出于安全原因时永久保存的所有者字段。
您需要确保实现这一目标。
你应该做什么？（）

You develop a serializable class for persisting objects as files.
Every time an object is serialized, you have to update the database with the name of the object and location of that file.
You elect to employ the OnSerialized attribute to achieve this objective.
You now need to apply the OnSerialized attribute to a certain method.
What should you do?（）

You have recently created a serializable class named Vehicle.
The class is shown below:
[Serializable]
public class Vehicle{
public string VIN;
public string Make;
public string Model;
public string Year;
}
You are planning to create a custom formatter class to control the formatting of Vehicle objects when they are serialized.
You need to ensure that is achieved with as little development effort as possible.
What should you do?（）

Certkiller.com has given you the task of serializing an object and writing it to a data file using binary serialization.
You need to ensure that you meet these requirements.
