This is how we can use the required methods of Array class in our applications to implement required functionality. The DataRow type provides ways to add, remove, or read cells from the enclosing. It narrows the data abstraction to the level of the row. A DataRow contains an individual row of data. If you observe the above result, we sorted the elements of an array and changed the order of array elements using Array class based on our requirements. VB.NET DataRow Examples Use the DataRow type to store values in a row in a DataTable. When we execute the above visual basic program, we will get the result as shown below. If you observe the above example, we are sorting and changing the order of array elements using Sort and Reverse methods of an Array class. WriteLine( '-Elements After Reverse-')Д¬onsole. WriteLine( '-Elements After Sort-')Д¬onsole. WriteLine( '-Initial Array Elements-')Д¬onsole. ' Declaring and Initializing an array with size of 5Дim array As Integer() = New Integer(4) Д¬onsole. In visual basic, Arrays can be declared by specifying the type of elements followed by the brackets () like as shown below. If you were to right-click on ComboBox1 in this statement and select 'Go To Definition', then file will open and you will be positioned at it. If you observe the above diagram, we are storing the values in an array starting from index 0 and it will continue to store the values based on the defined number of elements. Dim myUri As New Uri(Me.ComboBox1.Text) At this point in the initialization of the form, ComboBox1 may be declared but does not yet have an instance of the ComboBox class assigned to it. Suppose if we have an array with n elements, then it will start storing the elements from index 0 to n-1.ДЇollowing is the pictorial representation of storing the multiple values of the same type in a visual basic array data structure. In case, if we want to hold more than one value of the same data type, then the arrays came into the picture in visual basic to solve this problem.ДЄn array can start storing the values from index 0. In the previous chapter, we learned about variables in visual basic, which will help us to hold a single value like Dim id As Integer =10. In visual basic, Arrays are useful to store multiple elements of the same data type at contiguous memory locations and arrays will allow us to store the fixed number of elements sequentially based on the predefined number of items.
