Combining the newly created code into assemblies. Answer: A Jagged array is an array whose elements are arrays. The idea is relatively simple: Boxing is a process that converts a value type to an object type — by “boxing” the variable inside a dedicated object or interface. This is another programming language that .NET developers use, and it represents the lowest possible level for a language that humans can still read. This is a compiled code library that Microsoft developed as an open specification. Ans. Answer: The different types of Serialization are: XML serialization, SOAP, and Binary. For example, Collections has methods for finding the max element in a Collection. Sets doesn't contain duplicates whereas multiset can have duplicates. Set - There is no relevance of sequence and index. In Inheritance there is only one object in memory ( derived object ) whereas in Composition , parent object holds references of all composed objects. A Method that cannot be overriden in the sub class. Use these to test if your candidates can design and build quality applications using C#. A Single dimensional array is a linear array where the variables are stored in a single row. Members of StreamWriter are: Close(), Write(), Writeline(). Answer: A Class is an encapsulation of properties and methods that are used to represent a real-time entity. Programmatically, a class that raises an event is called a publisher and a class which responds/receives the event is called a subscriber. Examples of unmanaged code used in .NET include COM components, ActiveX interfaces and Win32 API functions. Pretend I’m a tech novice. Delegates are similar to function pointers in C/C++ and have the advantage of being type-safe. The delegates will be called in the order in which they are added. It is present in the namespace System. Encapsulation Allow the state of an object to be accessed and modified through behaviors. C# developers are in high demand today. Ans. This usually occurs in multi-threading. PerformtaskB tries to access ObjB which is locked by PerformtaskA. Consider a class called Patient. Here are 50 questions with their answers. System.out and System.err both represent the monitor by default and hence can be used to send data or results to the monitor. //----------------code to read-------------------//, //-------------code to write-------------------//, //-------Do Something with the deathDate event------------//, //--------Subscribe the function GetDeathDetails----------//, //--------Subscribe the function GetPatInfo ----------//, //Write Code to calculate Count of characters in a file//, //-----------------some code------------//, Class is Pass by reference (reference type), Can use waste collector for memory management, Cannot use Garbage collector and hence no Memory management, Following instructions and receiving feedback. The finally keyword is used to create a block of code that follows a try block. In the above Example, lock(ObjA) means the lock is placed on ObjA until this process releases it, no other thread can access ObjA. Abstraction lets you focus on what the object does instead of how it does it while Encapsulation means hiding the internal details or mechanics of how an object does something. You’ll also gain insight into whether they pay close attention to user experience. This is a Microsoft programming model and methodology that offers developers a way to manipulate data using a succinct yet expressive syntax. If you’re lucky enough to receive applications for this hard-to-fill position, you’ll want to go into the interviews ready to make quick decisions. SQL stands for Structured Query Language. Their answer may also touch on the transitive nature of inheritance — for example, the Ford class inherits from Car, which inherits from Vehicle. It is of 2 types, Compile-time and Runtime. Calculatecount() starts execution and calculates something. Ans. Software Engineer Interview Questions: Here are a few interview questions a software developer is usually asked by an interviewer. Answer: A Virtual method must always have a default implementation. Process is a program in execution whereas thread is a separate path of execution in a program. Read Robert Half's tips for making a graceful exit. You should use the Junior Developer C# programming interview questions in this section if you‘re looking for a junior or entry level developer with less experience. 500 is an integer. Ans. Xsd.exe tool converts the files to XSD format. It means whenever the myDel is called, both the subscribers get called. They are used when we want to read or write charact90, Reader-based data, respectively. Ans. Another way of understanding encapsulation is to think of it as “hiding” the state of an object as private or protected. They are interested in event deathEvent of type void. Ans. However, it can be overridden in the derived class, though not mandatory. Asynchronous call waits for the method to complete before continuing with the program flow.
