If you observe the above example, our variable text converted to upper case and even after we set the variable text as “ Rohini”, it displayed text as “ Suresh Dasari” because of the Set accessor validation fails in property. When we execute the above visual basic program, we will get the result as shown below. If you observe the above example, we are extending the behaviour of private variables ( name, location) using properties ( Uname, Ulocation) with Property keyword, Get and Set accessors by performing the some validations like to make sure Uname value is equals to only “ Suresh” using Set accessor and converting property text to uppercase with Get accessor. WriteLine( "Location: " & u.Ulocation)Ĭonsole. In visual basic properties, the Get accessor will be invoked while reading the value of property and when we assign a new value to the property, then the Set accessor will be invoked by using an argument that provides a new value.įollowing is the example of invoking the Get and Set accessors of properties in a visual basic programming language.Ĭonsole. So, if you want to make any changes to this field, you can do it only by calling the property ( UName). Here the field “ name” is marked as Private. If you observe above example, we are extending the behavior of Private variable name using property called Uname with Get and Set accessors by performing some validations like to make sure Uname value is equals to “ Suresh” using Set accessor and converting the property text to uppercase with Get accessor. In visual basic, Properties won’t accept any parameters and we should not pass property as a ref or out parameter in our application.įollowing is the simple example of defining the private variable and property in a visual basic programming language. In visual basic, the properties are categorized as three types, those are.Ī property which contains a both Get and Set accessors with Property keyword, we will call it as read-write property.Ī property which contains only Get accessor with ReadOnly property, we will call it as a read-only property.Ī property which contains only Set accessor with WriteOnly property, we will call it as write-only property. Here, the Get accessor code block will be executed whenever the property is read and the code block of Set accessor will be executed whenever the property is assigned to a new value.
If you observe the above syntax, we used an access modifier, Property keyword, and return type to define a property along with G et and Set accessors to make the required modifications to the class variables based on our requirements.
