2022-01-24 12:30:00 Explain Code Compilation in C#

There are four steps in code compilation which include:

Compiling the source code into Managed code by C# compiler.

Combining the newly created code into assemblies.

Loading the Common Language Runtime(CLR).

Executing the assembly by CLR. Открыть/Комментировать

2022-01-17 12:30:00 Explain type in C#

Anonymous types allow us to create a new type without defining them. This is way to defining read only properties into a single object without having to define type explicitly. Here Type is generating by the compiler and it is accessible only for the current block of code. The type of properties is also inferred by the compiler. Открыть/Комментировать

2022-01-10 12:30:01 In how many ways you can pass parameters to a method?

There are three ways that parameters can be passed to a method:

Value parameters − This method copies the actual value of an argument into the formal parameter of the function. In this case, changes made to the parameter inside the function have no effect on the argument.

Reference parameters − This method copies the reference to the memory location of an argument into the formal parameter. This means that changes made to the parameter affect the argument.

Output parameters − This method helps in returning more than one value. Открыть/Комментировать

2022-01-06 12:30:00 List some different ways for equality check in .NET

The ReferenceEquals() method - checks if two reference type variables(classes, not structs) are referred to the same memory address.

The virtual Equals() method. (System.Object) - checks if two objects are equivalent.

The static Equals() method - is used to handle problems when there is a null value in the check.

The Equals method from IEquatable interface.

The comparison operator == - usually means the same as ReferenceEquals, it checks if two variables point to the same memory address. The gotcha is that this operator can be override to perform other types of checks. In strings, for instance, it checks if two different instances are equivalent. Открыть/Комментировать
