You are creating a method by using C#. The method will accept three strings as parameters. The parameters are named string1, string2, and string3. The parameter values range from 5,000 to 15,000 characters.
The method will have the following signature.

You need to ensure that StringCompare only returns true if string1 concatenated to string2 is equal to string3. The comparison must be case-insensitive. The solution must ensure that StringCompare executes as quickly as possible.
Which three code blocks should you use to develop the solution? To answer, move the appropriate code blocks from the list of code blocks to the answer area and arrange them in the correct order. NOTE: Each correct selection is worth one point.

NEW QUESTION 6
You are developing an application. The application converts a Location object to a string by using a method named WriteObject.
The WriteObject() method accepts two parameters, a Location object and an XmlObjectSerializer object.
The application includes the following code. (Line numbers are included for reference only.)

You need to serialize the Location object as XML. Which code segment should you insert at line 20?

• A. new XmlSerializer(typeof(Location))
• B. new NetDataContractSerializer()
• C. new DataContractJsonSerializer(typeof (Location))
• D. new DataContractSerializer(typeof(Location))

Answer: D

Explanation: The code is using [DataContract] attribute here so need to use DataContractSerializer class. The DataContractJsonSerializer class serializes objects to the JavaScript Object Notation (JSON) and deserializes JSON data to objects.
Use the DataContractJsonSerializer class to serialize instances of a type into a JSON document and to deserialize a JSON document into an instance of a type.

NEW QUESTION 7
An application includes a class named Person. The Person class includes a method named GetData. You need to ensure that the GetData() method can be used only by the Person class and not by any class derived from the Person class.
Which access modifier should you use for the GetData() method?

• A. Public
• B. Protected internal
• C. Internal
• D. Private
• E. Protected

Answer: B

Explanation: The protected keyword is a member access modifier. A protected member is accessible within its class and by derived class instances.

NEW QUESTION 9
You are creating a console application by using C#. You need to access the application assembly. Which code segment should you use?

• A. Assembly.GetAssembly(this);
• B. this.GetType();
• C. Assembly.Load();
• D. Assembly.GetExecutingAssembly();

Answer: D

Explanation: Assembly.GetExecutingAssembly - Gets the assembly that contains the code that is currently executing.
Reference: http://msdn.microsoft.com/enus/ library/system.refilection.assembly.getexecutingassembly(v=vs.110).aspx Incorrect:
Not A: Assembly.GetAssembly - Gets the currently loaded assembly in which the specified class is defined.

You need to write a method that retrieves data from a Microsoft Access 2013 database. The method must meet the following requirements:
Be read-only.
Be able to use the data before the entire data set is retrieved.
Minimize the amount of system overhead and the amount of memory usage. Which type of object should you use in the method?

• A. DbDataReader
• B. DataContext
• C. unTyped DataSet
• D. DbDataAdapter

Answer: A

Explanation: DbDataReader Class
Reads a forward-only stream of rows from a data source.

NEW QUESTION 11
You are developing an application by using C#. You have the following requirements:
Support 32-bit and 64-bit system configurations.
Include pre-processor directives that are specific to the system configuration. Deploy an application version that includes both system configurations to testers. Ensure that stack traces include accurate line numbers.
You need to configure the project to avoid changing individual configuration settings every time you deploy the application to testers.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

• A. Update the platform target and conditional compilation symbols for each application configuration.
• B. Create two application configurations based on the default Release configuration.
• C. Optimize the application through address rebasing in the 64-bit configuration.
• D. Create two application configurations based on the default Debug configuratio

Answer: AD

Explanation: A: “include pre-processor directives that are specific to the system configuration” system configuration here refers to bitness ie 32-bit or 64-bit
so the developer wants to use in code different pre-processor directives for 32/64 bit,
this is achieved by defining and using conditional compilation symbols for different platform targets (platform target is VS term for bitness ie for 32/64 bit).
D (not B): The question about testing, debugging, stack trace, line numbers etc. There is not a single word about release
