DataTableCollection.Remove Method (String)

Removes the DataTable object with the specified name from the collection.

Namespace:  System.Data
Assembly:  System.Data (in System.Data.dll)

Public Sub Remove ( _
	name As String _


Type: System.String

The name of the DataTable object to remove.


The collection does not have a table with the specified name.

The CollectionChanged event occurs when a table is successfully removed.

To determine whether a given table exists and can be removed before invoking Remove, use the Contains and the CanRemove methods.

The following example uses the Contains and CanRemove methods to test whether a named table exists and can be removed. If so, the Remove method is called to remove the table.

Private Sub RemoveTables()
   ' Set the name of the table to test for and remove. 
   Dim name As String = "Suppliers" 

   ' Presuming a DataGrid is displaying more than one table, get its DataSet. 
   Dim thisDataSet As DataSet = CType(DataGrid1.DataSource, DataSet)
   Dim tablesCol As DataTableCollection = thisDataSet.Tables
   If tablesCol.Contains(name) _
   And tablesCol.CanRemove(tablesCol(name)) Then 
   End If 
End Sub
