adding/removing objects to a list in vb.net - vb.net

Question

i have a list of objects called gobletinv that i want to add and remove objects from
right now to add a new object I've just done this
gobletinv(gobletpointer).mainstattype = MST.Text
gobletinv(gobletpointer).mainstatvalue = MSV.Text
gobletinv(gobletpointer).substat1type = ST1.Text
gobletinv(gobletpointer).substat1value = SV1.Text
gobletinv(gobletpointer).substat2type = ST2.Text
gobletinv(gobletpointer).substat2value = SV2.Text
gobletinv(gobletpointer).substat3type = ST3.Text
gobletinv(gobletpointer).substat3value = SV3.Text
gobletinv(gobletpointer).substat4type = ST4.Text
gobletinv(gobletpointer).substat4value = SV4.Text
gobletpointer += 1
i currently have no idea how i would remove an object from this list

Answer 1

Let's assume that the type your collection holds is called Stat. Let's also assume that gobletpointer is an Integer with an initial value of 0.
Each line where you are referencing the collection, you start it off with:
gobletinv(gobletpointer)
What this does is get the item from the collection at a given index.
So right now when you set the various property values to their respective TextBox value, you are overwriting the existing item in the collection.
If you wanted to add a new item to the collection, you would use the Add method (documentation). For example:
gobletinv.Add(New Stat() With {
mainstattype = MST.Text,
mainstatvalue = MSV.Text
substat1type = ST1.Text,
substat1value = SV1.Text,
substat2type = ST2.Text,
substat2value = SV2.Text,
substat3type = ST3.Text,
substat3value = SV3.Text,
substat4type = ST4.Text,
substat4value = SV4.Text
})
Now if you wanted to remove the object from the collection, it depends on how you want to remove it. But here is an example of leveraging the RemoveAt method (documentation) to remove the first record from the collection:
gobletinv.RemoveAt(0)
