i am not getting the values in textbox.
You say you want to show array value in textbox but you write code for assigning textbox value in an array!

getting error as "Conversion from string "" to type 'Double' is not valid."
You get this error as you are trying to assign a string (textbox.text) to an array of type double. Invalid!

display of array in textbox
What exactly you are trying to display here? Whole array as a string? Array in matrix format? Or you want to access any specific value form array and display it?

Solution 2

Try this:

VB

Dim value(,) As Double = New Double(,) {{1, 2}, {3, 4}, {5, 6}, {44, 66}}
       For i As Integer = 0 To UBound(value, 1)
           TextBox1.Text &= String.Format("{0}{1}{2}", value(i, 0).ToString.PadLeft(10), value(i, 1).ToString.PadLeft(10), vbNewLine)
       Next

To your 2nd question :

VB

Dim value(,) As Double = New Double(,) {{0, 0}}
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim maxDim0 As Integer = UBound(value, 1)
        Dim maxDim1 As Integer = UBound(value, 2) + 1

        ReDim Preserve value(maxDim0, maxDim1)
        value(maxDim0, 0) = Double.Parse(TextBox2.Text)
        value(maxDim0, 1) = Double.Parse(TextBox3.Text)

        For i As Integer = 0 To UBound(value, 1)
            TextBox1.Text &= String.Format("{0}{1}{2}", value(i, 0).ToString.PadLeft(15), value(i, 1).ToString.PadLeft(15), vbNewLine)
        Next
    End Sub
