VB.net DataSet to Array

Question

I want my DataSet query results to be transferred to an array.

Here is my query:

This is the only way I know to display the contents of my query: Trans_TableTableAdapter.SelectDistinct(DBDataSet.Trans_Table)

My problem is I don't know how to apply this query to an array.

This is the last piece of my puzzle, I really need help to complete my project. Thanks in advance.

Answer 1

So you want a String() from the query that returns a single column? You can use LINQ:

Dim accounts As String() = DBDataSet.Trans_Table.AsEnumerable().
    Select(Function(row) row.Field(Of String)("Account")).
    ToArray()

If you prefer query syntax:

Dim accounts = From row In DBDataSet.Trans_Table.AsEnumerable()
               Select row.Field(Of String)("Account")
Dim accountArray As String() = accounts.ToArray()

Since that seems to be a strongly typed DataSet there should be a named column which you can use directly:

Dim accounts = From row In DBDataSet.Trans_Table Select row.Account
Dim accountArray As String() = accounts.ToArray()
