So I am wanting to pass a string value wit the name of the table in it. There are multiple tables, so each will be called at a specific time.

so instead of

profiledt.Rows

is there a way to do something like this ["profiledt"].rows

What I have tried:

I have googled, but could not find any answers that helped with this issue.

You could use a function that takes the table name as a parameter, something like this example: Visual Basic .NET Language - Simple Function to read from Database and return as DataTable | vb.net Tutorial[^]

Yes, you can!

VB

Dim ds As DataSet = New DataSet()
'add 5 datatables with example data
For i= 1 To 5
	Dim dt As DataTable = New DataTable(String.Format("Table{0}", i))
	dt.Columns.AddRange(New DataColumn()  _
		{ _
			New DataColumn("ID", Type.GetType("System.Int32")), _
			New DataColumn("Description", Type.GetType("System.String")) _
		})
	dt.Rows.Add(New Object(){1, "SomeData"})
	ds.Tables.Add(dt)
Next

'get datatable by its name:
Dim d = ds.Tables("Table1")
'd variable is ready to use!
