Creating Using Dynamic Array Length in Asp.Net C# VB.Net

In some cases developers need to use dynamic array in But it’s not straight forward as like VB. If you were a VB developer then you knew that for dynamic array’s VB uses REDIM keyword to generate dynamic array’s. Here in this post i will discuss how developer can use dynamic arrays in pages where developer don’t need to mention the array size or length before. Basically there is no straight forward way to use but you can achieve the dynamic size by using a collection named ArrayList. The ArrayList collection provide us to add any type of object (int, float, string, object, collection, user defined datatype) in its index by using ADD() method and by using count method we will know how many object the ArrayList currently hold. So let’s go for an example on dynamic arrays in both C# and VB.Net.

C# Dynamic Array Example:

    protected void Page_Load(object sender, EventArgs e)
        ArrayList Dynamic_List = new ArrayList();

        for (int i = 0; i < 5; i++)

        Dynamic_List.Add("You can put Object/any datatype here !!");

        for (int i = 0; i < Dynamic_List.Count; i++)
            Response.Write("Index " + i.ToString() + ": " + Dynamic_List[i].ToString() + "</br>");

Note: Don’t forget to add “System.Collections” namespace.

VB.Net Dynamic Array Example:

    Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load
        Dim Dynamic_List As New ArrayList()
        Dim i As Integer

        For i = 0 To 5
        Next i

        Dynamic_List.Add("You can put Object/any datatype here !!")

        For i = 0 To Dynamic_List.Count - 1
            Response.Write("Index " + i.ToString() + ": " + Dynamic_List(i).ToString() + "</br>")
        Next i
    End Sub

Note: Don’t forget to add “System.Collections” namespace.
