Resizing a two dimensional Array
How can I resize the two dimensional array size without affe开发者_开发知识库cting its value?
Use Didn't read the documentation right. ReDim
with the Preserve
modifier. VB.NET will make sure the original values are untouched.ReDim Preserve
will only allow you to change the length of the last dimension of the array.
You need to allocate a new array (with the correct size) and manually copy the elements from the first array to the second.
As Adam said, you can't resize 2D arrays dynamically. You can easily copy the existing array into a bigger one like so:
Dim smaller(1, 1) As Byte
Dim bigger(2, 2) As Byte
Array.Copy(smaller, bigger, smaller.length)
Try using array.resize
if you are on .net 2 framework or above.
For example:
Dim MyArray() as string
Array.Resize(myarray,12)
