This is a trick question and depends on what you mean by "high performance".If you mean "do something that is non-standard" then probably c++.If you mean using existing tools then both c# AND vb.net are adequate.But again, it depends on what you mean.

It is not permitted to declare modifier on the members in an interface definition
A) TrueB) False
pankajbanga

Interface members are implicitly public, explicit modifiers are not allowed.
Rohit Sharma

A is the correct answer. By default all the members in an Interface definition are public, so there is no need to declare access modifier public. It would be a compile time error otherwise.

Which method is implicitly called when an object is created

When a obeject create then constructor of the class execute at that moment. If you don't define any constructor in a class then JVM pass a default constructor but if you define any parametrized constructor in class then this is programmers responsiblity to pass default constructor in that class.

If we can'nt make the object of abstract class what is the use of defining of data members and non abstract functions in that abstract class?
Sreedhar
- Jan 25th, 2007
Its basically for Polymorphism, So that we can call same method on different classes based on the subtype.Say you implement a factory and get back the subclass requried, then u can call the method without any issue as all the subclassed implment the same abstract class.

What are Indexers?What is the use of it,and when to use Indexers?
baccha
- Jul 20th, 2011
An indexer allows an instance of a class or a struct to be indexed as an array,which is useful for looping or iterating or data binding operations.

Indexers are one neat feature of C#. They allow us to access a particular class as it is an array. They are similar to the properties in means that they encapsulate method calls into more convenient r...

How do I do implement a trace and assert?
Use a conditional attribute on the method, as shown below: class Debug{[conditional("TRACE")]public void Trace(string s){Console.WriteLine(s);}}class MyClass{public static void Main(){Debug.Trace("hello");}}In this example, the call to Debug.Trace() is made only if the preprocessor symbol TRACE is defined at the call site. You can define preprocessor symbols on the command line by using the /D switch....

Is there an equivalent to the instanceof operator in Visual J++?
C# has the is operator: expr is type
Elean0r
- May 24th, 2011
The C# "is" operator can be used to test whether an object reference ( run-time type) is compatible with a defined type? ( compile type). ?The operator returns a Boolean result and is hence most often used within an if statement.

Is there a way of specifying which block or loop to break out of when working with nested loops?
The easiest way is to use goto: using System;class BreakExample {public static void Main(String[] args) {for(int i=0; i<3; i++) {Console.WriteLine("Pass {0}: ", i);for( int j=0 ; j<100 ; j++ ) {if ( j == 10) goto done;Console.WriteLine("{0} ", j);}Console.WriteLine("This will not print");}done:Console.WriteLine("Loops complete.");}}
