What are threads (multi-threading) in C# ?

2015-10-11T20:31:00.002+05:30

Threads are the independent units of execution and can run simultaneously with other threads. Threads helps in achieving parallel execution in C#, which is also called multithreading.

A C# program typically starts with a single thread create automatically by CLR (Common Language Runtime) and operating system. If needed, additional threads has to be created manually through code.

How to measure execution speed (time) in Milliseconds, Microseconds and Nanoseconds using Stopwatch in C# ?

2015-10-10T11:35:00.000+05:30

There are situations in the programming world where developers need to measure the execution time of the code.
.NET framework provides Stopwatch class to measure elapsed time for an interval which has two properties ElapsedMilliseconds and ElapsedTicks.

What is difference between DateTime.Now and DateTime.UtcNow ?

2015-10-04T21:51:00.002+05:30

DateTime.Now is a built in property provided by .NET framework which returns the current time of the machine which is executing the code.
This property internally converts the DateTime.UtcNow provided value to the date and time format of the machine executing the code. Hence this property has an overhead of execution, so must be used carefully.

What is IL (Intermediate Language) in .Net framework ?

2015-09-20T14:40:00.000+05:30

Intermediate Language is also known as MSIL (Microsoft Intermediate Language) or CIL (Common Intermediate Language). All .NET source code is compiled to IL. IL is then converted to machine code at the point where the software is installed, or at run-time by a Just-In-Time (JIT) compiler.

What is Object-Oriented Programming ?

2015-05-03T15:41:00.000+05:30

Object-oriented programming (OOP) is a programming language model organized around "OBJECTS" instead of "actions" and data rather than logic. In procedural programming language, a program has been viewed as a logical procedure that takes input data, processes it, and produces output data.

What is C# programming language ?
