Microsoft Programming in C# - 70-483 FREE EXAM DUMPS QUESTIONS & ANSWERS
You are developing an application by using C#. The application will process several objects per second.
You need to create a performance counter to analyze the object processing.
Which three actions should you perform in sequence? (To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.)
You need to create a performance counter to analyze the object processing.
Which three actions should you perform in sequence? (To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.)
Correct Answer:
1 - Create a CounterCreationDataCollection collection. Then create the counters as CounterCreationData objects and set the necessary properties.
2 - Add the CounterCreationData objects to the collection by calling the Add() method of the collection.
3 - Call the Create() method of the PerformanceCounterCategory class and pass the collection to the method.
Explanation:
Note:
Example:
CounterCreationDataCollection counterDataCollection = new CounterCreationDataCollection(); // Box1
// Add the counter. Box 1
CounterCreationData averageCount64 = new CounterCreationData();
averageCount64.CounterType = PerformanceCounterType.AverageCount64;
averageCount64.CounterName = "AverageCounter64Sample";
counterDataCollection.Add(averageCount64);
// Add the base counter.
CounterCreationData averageCount64Base = new CounterCreationData();
averageCount64Base.CounterType = PerformanceCounterType.AverageBase;
averageCount64Base.CounterName = "AverageCounter64SampleBase";
counterDataCollection.Add(averageCount64Base); // Box 2
// Create the category. Box 3
PerformanceCounterCategory.Create("AverageCounter64SampleCategory",
"Demonstrates usage of the AverageCounter64 performance counter type.", PerformanceCounterCategoryType.SingleInstance, counterDataCollection);
You are developing an application that will write string values to a file. The application includes the following code segment. (Line numbers are included for reference only.)
01 protected void ProcessFile(string fileName, string value)
02 {
03
04 }
You need to ensure that the ProcessFile() method will write string values to a file.
Which four code segments should you insert in sequence at line 03? (To answer, move the appropriate code segments from the list of code segments to the answer area and arrange them in the correct order.)

Which four code segments should you insert in sequence at line 03? (To answer, move the appropriate code segments from the list of code segments to the answer area and arrange them in the correct order.)
Correct Answer:
Explanation:
Note:
* Example:
1. StreamWriter.Null Field
Provides a StreamWriter with no backing store that can be written to, but not read from.
2. The StreamWriter Constructor (String) initializes a new instance of the StreamWriter class for the specified file by using the default encoding and buffer size.
3. The StreamWriter.Write method writes data to the stream.
4. The StreamWriter.Close method closes the current StreamWriter object and the underlying stream.
Incorrect:
Not StreamWrite.Open();
The StreamWriter Class does not have any method named Open.

You are developing an application that includes a class named Order. The application will store a collection of Order objects.
The collection must meet the following requirements:
* Internally store a key and a value for each collection item.
* Provide objects to iterators in ascending order based on the key.
* Ensure that item are accessible by zero-based index or by key.
You need to use a collection type that meets the requirements.
