The built-in data type in C# is called primitive data types. Here we are giving you the range of most commonly used primitive data types in C#. Data Type Description Size (bits) Range int Whole numbers 32 <->‡231 through 231 <-> 1 long Whole numbers 64 <-> §263 through 263 <-> 1 Float Floating-point …
Creating Fields and Using Initializers The first type of class member we’ll take a look at is the field, also called a data member.Outside any method, A field is just a class-level variable, outside any method.

Standard operators list are given below. Note that when we are writing any classes classes it is possible to change the default behaviors of some …
Type conversion is a process of converting one type into another. Using C# type conversion techniques, not only you can convert data types, you can convert object types also. The type conversion in C# can be either implicit conversion or an explicit conversion. If one type of data is automatically converted into another type …
“The great power comes with a great responsibility.” Enums are basically a set of named constants. They are declared in C# using the keyword enum. Every enum type automatically derives from System.Enum namespace and thus we can use System.Enum methods on our Enums. Enums are value types and are created on the stack …
At the first, what is type safe code and why is it relevant to secure programming? Type safety is certainly one of the most confusing aspects for somebody learning .Net.

If you want a method to return information (means its return type is not void). You must write a return statement inside the method. You can do this by using the keyword return followed by an expression that calculates the returned value and a semi colon. The return value type must be the same …
