Public static void Main(String args) // Main Method We can create multiple objects each of the objects have its copy of the instance variable. In the program, the instance variables are markEnglish, markMaths. For instance variables, we can use the access specifiers. These variables are created once the object of a class created and it will destroy when the object becomes destroyed. Instance variables are called the non-static variables the instance variables are declared in a class but declared outside of any method, block or constructor. Instance Variables or Non – Static Variables WriteLine("Customer Age: "+ customer_age) ĬustomerEntry _customerObj=new CustomerEntry() Ģ. The compiler will generate an error, once we apply the variable customer_age outside GetAge() function.Ĭonsole. In the sample program, the variable “customer_age” is a local variable to the function GetAge(). The variable is created when the function is called or the block is entered and it will be demolished once after existing from block or while the call returns from the function. Once the variable is declared, those variables exist only within the block and we can access these variables only within the block.

Instance Variables or Non – Static VariablesĪ local variable defined within a method or block or constructor.

There are several types of variable, such as To assign a value to a variable called initialization, variables can be initialized with an equal sign by the constant expression, variables can also be initialized at their declaration.Ĭhar name='Rock' Types of Variables in C# with Examples

Int value = 100 How to Initialize Variables in C#? You can also initialize a variable at the time of definition as follows, They are some suitable methods to describe the variable names in c# programming language. is the name of a variable that holds the value in our application and is assigning a specific value to the variable and finally is used to give access permission for the variable. Here the is a type of data in which the variable can hold the types they are an integer, Sting, float and so on. Variable names should not contain any reserve keywords like int, char, float and so on.There should not be any white space allowed in between the variable name.Every variable name should start with alphabets or underscore.We must define a variable name with the combination of numbers, alphabets and underscore.

Start Your Free Software Development Course There are some rules to declare C# Variables:

The value of a variable can be changed at any time until the program accessibility.

Values must be assigned to a variable before we make use of it otherwise, it will show a compile-time error.

Variables can be defined by multiple separated by a comma and also in single and multi-line till the end of the semicolon.

Declaration and initialization of variables are in separate statements.

Variables can hold the value of particular data types, for example, int, string, float and so on.

Variables are nothing but a name given to data value.

Let’s see a few basic things about variables, To perform any operation on variables it is essential to define a variable with a particular data type to specify the type of data that the variable can hold in our application.

All the variables should be declared before they are in use every variable has a specific type that decides the size and range of variables. RandomAccessFile enables us to write at a specific position in the file given the offset - from the beginning of the file - in bytes.In C#, a variable is a name that we give to the memory location and every variable has a specified type that specifies the type of values that can be stored in a variable. Let's now illustrate how to write and edit inside an existing file rather than just writing to a completely new file or appending to an existing one.
