Question No: 85 DRAG DROP – (Topic 1)

You are developing an application by using C#. The application will output the text string quot;First Linequot; followed by the text string quot;Second Linequot;.

You need to ensure that an empty line separates the text strings.

Which four code segments should you use in sequence? (To answer, move the appropriate code segments to the answer area and arrange them in the correct order.)

Dumps4Cert 2018 PDF and VCE

Answer:

Dumps4Cert 2018 PDF and VCE

Explanation:

Box 1:

Dumps4Cert 2018 PDF and VCE

First we create the variable. Box 2:

Dumps4Cert 2018 PDF and VCE

We create the first text line. Box 3:

Dumps4Cert 2018 PDF and VCE

We add a blank line.

The StringBuilder.AppendLine method appends the default line terminator to the end of the current StringBuilder object.

Box 4:

Dumps4Cert 2018 PDF and VCE

Finally we add the second line.

Question No: 86 – (Topic 1)

You are developing an application that accepts the input of dates from the user.

Users enter the date in their local format. The date entered by the user is stored in a string variable named inputDate. The valid date value must be placed in a DateTime variable named validatedDate.

You need to validate the entered date and convert it to Coordinated Universal Time (UTC). The code must not cause an exception to be thrown.

Which code segment should you use?

Dumps4Cert 2018 PDF and VCE

  1. Option A

  2. Option B

  3. Option C

  4. Option D

Answer: A Explanation:

AdjustToUniversal parses s and, if necessary, converts it to UTC.

Note: The DateTime.TryParse method converts the specified string representation of a date and time to its DateTime equivalent using the specified culture-specific format information and formatting style, and returns a value that indicates whether the conversion succeeded.

Question No: 87 DRAG DROP – (Topic 1)

You are developing an application that includes a class named Customer.

The application will output the Customer class as a structured XML document by using the following code segment:

Dumps4Cert 2018 PDF and VCE

You need to ensure that the Customer class will serialize to XML.

How should you complete the relevant code? (To answer, drag the appropriate code segments to the correct locations in the answer area. Each code segment may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.)

Dumps4Cert 2018 PDF and VCE

The EmployeeType property value must meet the following requirements:

-> The value must be accessed only by code within the Employee class or within a class derived from the Employee class.

-> The value must be modified only by code within the Employee class.

You need to ensure that the implementation of the EmployeeType property meets the requirements.

Which two actions should you perform? (Each correct answer represents part of the complete solution. Choose two.)

  1. Replace line 03 with the following code segment: public string EmployeeType

  2. Replace line 06 with the following code segment: protected set;

  3. Replace line 05 with the following code segment: private get;

  4. Replace line 05 with the following code segment: protected get;

  5. Replace line 03 with the following code segment: protected string EmployeeType

  6. Replace line 06 with the following code segment: private set;

Answer: E,F
