In visual basic, we can insert elements into the list either by using Insert() or InsertRange() methods.įollowing is the example of inserting elements into the list by using Insert and InsertRange methods in visual basic.To add the controls to the Userform, execute the following steps.ġ. When we execute the above visual basic program, we will get the result like as shown below. If you observe the above example, we are accessing generic list elements in different ways by using index positions, For and For Each loops based on our requirements. In visual basic, we can add elements to the list either by using Add / AddRange methods or at the time of initialization based on our requirements.įollowing is the example of adding elements to the list using Add or AddRange methods in visual basic.ĭim lst As List( Of Integer) = New List( Of Integer)() From ", u.Id, u.Name, u.Location) This is how we can use the generic list in visual basic to store the group of defined type elements based on our requirements.įollowing are the some of useful examples to work with generic list in visual basic programming language. When we execute the above visual basic program, we will get the result as shown below. Here, we added only the defined data type ( Integer, String) values to the newly created lists ( lst, lst2) by using the Add method and accessing the generic list ( lst, lst2) elements by using For Each loop. If you observe the above example, we are able to define a new generic lists ( lst, lst2) collection. WriteLine( "List2 Capacity: " & lst2.Capacity)Ĭonsole. WriteLine( "List2 Elements Count: " & lst2.Count)Ĭonsole. WriteLine( "List1 Capacity: " & lst.Capacity)Ĭonsole. WriteLine( "List1 Elements Count: " & lst.Count)Ĭonsole. Visual Basic Generic List (List(Of T)) Exampleįollowing is the example of using the generic list ( List(Of T)) in visual basic programming language.ĭim lst As List ( Of Integer) = New List ( Of Integer)()ĭim lst2 As List ( Of String) = New List ( Of String)()Ĭonsole. It will copies the elements of List to new array object. It is used to remove a range of elements from the List. It is used to remove an element from the list based on the specified index position. It is used to remove the first occurrence of specified element from the List. It is used to insert all the elements of specified collection into List starting from the specified index. It is used to insert an element into the list at the specified index. It is used to iterate through the List to access elements. It is used to retrieve all the elements that matches the conditions defined by the specified predicate. It is used to search for an element that matches the conditions defined by the specified predicate and returns the first occurrence of the List. It is used to copy entire List to a compatible one-dimensional array. It is used to determine whether the specified element exists in the List or not. It will remove all the elements from the List. It is used to add all the elements of specified collection at the end of the List. It is used to add an element at the end of the List. It is used get or set an element at the specified index.įollowing are the some of commonly used methods of generic list to perform add, search, insert, delete or sort operations in a visual basic programming language. It is used to get the number of elements in list. It is used to get or set the number of elements a list can contain. The following are some of the commonly used properties of the generic list in a visual basic programming language. If you observe the above example, we defined a list ( lst) with String data type to store only string elements. Dim lst As List( Of String) = New List( Of String)()
