Q.6. What are the benefits of using the ExpandoObject class over a using dictionary?

• It offers easier data binding from XAML.

• It’s interoperable with dynamic languages, which will be expecting DLR properties rather than dictionary entries.

• WPF data binding will understand dynamic properties, so WPF controls can bind to an ExpandoObject more readily than a dictionary.

• ExpandoObject can help in creating complex hierarchical objects. ExpandoObject implements the INotifyPropertyChanged interface, which gives more control over properties than a dictionary.

• private string Tabs(uint numTabs) { StringBuilder sb = new StringBuilder(); for (uint i = 0; i <= numTabs; i++) { sb.Append(“\t”); } return sb.ToString(); }

• private string Tabs(uint numTabs) { string output = “”; for (uint i = 0; i <= numTabs; i++) { output += ‘\t'; } return output; }

• private string Tabs(uint numTabs) { String output = new String(‘\t’, numTabs); return output; }

Q.12. There is a class that has a public int counter field that is accessed by multiple threads. This int is only incremented or decremented. To increment this field, three thread-safe approaches are mentioned below:

A) lock(this.locker) this.counter++;
B) Interlocked.Increment(ref this.counter);
C) Change the access modifier of counter to public volatile

Which statement is incorrect with regards to these approaches?

• All 3 are equivalent and can be used interchangeably.

• Though A is safe to do, it prevents any other threads from executing any other code which is guarded by locker.

• B is the best approach as it effectively does the read, increment, and write in ‘one hit’ which can’t be interrupted.

• C on it’s own isn’t actually safe at all. The point of volatile is that multiple threads running on multiple CPU’s can, and will, cache data and re-order instructions.

__________________________________________________________________

Q.13. What will happen if the following code is compiled in .NET 4 or above (Assume required namespaces are included)?

public class var { }
public class main
{
    public static void main(string[] args)
    {
        var testVar = new var();
    }
}

 

• This code will not compile, as var is a reserved keyword, so it can not be used as a class name.

• This code will compile, as var is merely a contextual keyword and it is used to provide a specific meaning in the code, so it will cause no problems.

• This code will not compile, as a new object cannot be created like var testVar = new var();

• None of these.

__________________________________________________________________

Q.14. Which object oriented term is related to protecting data from access by unauthorized functions?

• Inheritance

• Data hiding

• Polymorphism

• Operator overloading

• Abstraction

• List<string> ls = new List<string>(); ls.Add(“one”); ls.Add(“two”); string type = string.Join(“,”, ls.ToArray());

• string commaSeparatedList = input.Aggregate((a, x) => a + “, ” + x)

• public static string Join(this IEnumerable<string> source, string separator) { return string.Join(separator, source); }

__________________________________________________________________

Q.19. What is the advantage of using IList<T> over List<T>?

 

• IList<T> uses reflection, which is the most efficient way to process an object inside memory.

• IList<T> implements hashing to store objects in the collection; which produces optimum performance.

• Using IList<T> rather than List<T> allows the code to be more flexible. It can replace the implementation with any collection that implements IList<T> without breaking any calling code.

• IList<T> only allows immutable types to be stored inside the collection.

        s1 = "New Value";
        Console.WriteLine(s2);

• “New Value”, because string is a reference type.

• “Old Value”, because string is a value type.

• “New Value”, because string is a value type.

• “Old Value”, because string is a reference type.

• “Old Value”, because string is a reference type which is treated as a special case by the assignment operator.

Q.39. What will be the output if in a WinForms application, the following code is executed in the Load event of a form? Assume this form has lblMessage as a Label Control.

private void Form1_Load(object sender, EventArgs e)
{
    try

    }
    catch (Exception ex)
    {
    }
}

}

class Y : X { }

 

• c

• f

• i

• All of these

Q.45. If i == 0, why is (i += i++) == 0 in C#?

 

• //source code i += i++; //abstract syntax tree += / \ i i (post) \ ++

• // source code i += i++; //abstract syntax tree += / \ i ++ (post) \ i First, i++ returns 0. Then i is incremented by 1. Lastly i is set to the initial value of i which is 0 plus the value i++ returned, which is zero too. 0 + 0 = 0.

• int i = 0; i = i + i; i + 1;

• int ++(ref int i) { int c = i; i = i + i; return c;}

• int FindSum (object[] values) { int sum = 0; foreach (object o in values) { int? x = o as int?; if (x.HasValue) { sum += x.Value; } } return sum; }

• int FindSum (object[] values) { int sum = values.OfType<int>().Sum(); return sum; }

Q.47. Consider the following code block:
 
public class Person
{
    public string GetAge()
    {
        lock (this)
        {
            // Code to get Age of this person object.
        }
    }
}

Which of the following statements is true?

 

• lock(this) actually modifies the object passed as a parameter, and in some way makes it read-only or inaccessible.

• lock(this) can be problematic if the instance can be accessed publicly, because code beyond one’s control may lock on the object as well. This could create deadlock situations where two or more threads wait for the release of the same object.

• lock(this) marks current object as a critical section by obtaining the mutual-exclusion lock for a given object, all private fields of the object become read-only.

• Implement locking using current application instance or some private variable is absolutely the same and does not produce any synchronization issue, either technique can be used interchangeably.

            Read = 1,
            Write = 2,
            Delete = 4
        }

What will be the output of the following Main program (which has access to the enum defined above) in this C# console application (Assume required namespaces are included) :

static void Main(string[] args)
{
    var permissions = Permissions.Read | Permissions.Write;

        default:
            sValue = "-1";
            break;
    }
    return sValue;
}

• The code will not compile as there shouldn’t be a break statement in the default case label.

• The code will compile but if case 1 is passed as the input parameter to the function, the code for case 2 will also execute (after the code for case 1), and so the wrong value may be returned.

• The code will compile and run without any issues.
