61. What is the difference between Compiler and Interpreter?
Compiler :A compiler is a program that translates program (called source code) written in some high level language into object code.
Interpreter:
An interpreter translates high-level instructions into an intermediate form, which it then executes. Interpreter analyzes and executes each line of source code in succession, without looking at the entire program; the advantage of interpreters is that they can execute a program immediately. .
62. What is a class?
Class is concrete representation of an entity. It represents a group of objects, which hold similar attributes and behavior. It provides abstraction and encapsulations.
63. What is an Object?
Object represents/resembles a Physical/real entity. An object is simply something you can give a name.
64 What is Abstraction?
Hiding the complexity. It is a process of defining communication interface for the functionality and hiding rest of the things.
65. How do you convert a string into an integer in .NET?
Int32.Parse(string)
Convert.ToInt32()
66. Describe the compilation process for .NET code?
Source code is compiled and run in the .NET Framework using a two-stage process. First, source code is compiled to Microsoft intermediate language (MSIL) code using a .NET Framework-compatible compiler, such as that for Visual Basic .NET or Visual C#. Second, MSIL code is compiled to native code.
67. What Is Boxing And Unboxing?
Boxing :
Boxing is an implicit conversion of a value type to the reference type.
Examples : Stuct Type, Enumeration Type
UnBoxing :
Unboxing is an explicit conversion from the reference to a value type.
Examples : Class , Interface.
68. How do you create threading in .NET? What is the namespace for that?
System.Threading.Thread
69. What is Method overloading?
Method overloading occurs when a class contains two methods with the same name, but different signatures.
70. What is Method Overriding?
An override method provides a new implementation of a member inherited from a base class. The method overridden by an override declaration is known as the overridden base method.
71. What is difference between inline and code behind?
Inline code written along side the html in a page. Code-behind is code written in a separate file and referenced by the .aspx page.
72. What is an abstract class?
An abstract class is a class that must be inherited and have the methods overridden. An abstract class is essentially a blueprint for a class without any implementation.
73. What is the difference between datagrid and gridview?
Datagrid is used in windows application and gridview is used in web and in datagrid we cannot write the code for datagrid properties where as for grid view we can write the code like template column item template etc this will not be done in datagrid.
74. What is the use of System.Diagnostics.Process class?
The System.Diagnostics namespace provides the interfaces, classes, enumerations and structures that are used for tracing.
The System.Diagnostics namespace provides two classes named Trace and Debug that are used for writing errors and application execution information in logs.
75. What is the difference between static or dynamic assemblies?
Assemblies can be static or dynamic.
Static assemblies :
can include .NET Framework types (interfaces and classes), as well as resources for the assembly (bitmaps, JPEG files, resource files, and so on).Staticassemblies are stored on disk in portable executable (PE) files.
Dynamic assemblies :
which are run directly from memory and are not saved to disk before execution. You can save dynamic assemblies to disk after they have executed.
