DataTableCollection.Add Method (String, String)


Creates a DataTable object by using the specified name and adds it to the collection.

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

Public Function Add (
	name As String,
	tableNamespace As String
) As DataTable


Type: System.String

The name to give the created DataTable.

Type: System.String

The namespace to give the created DataTable.

Return Value

Type: System.Data.DataTable

The newly created DataTable.

Exception Condition

A table in the collection has the same name. (The comparison is not case sensitive.)

If either null or an empty string ("") is passed in, a default name is given to the newly created DataTable. This name is based on the order in which the table was added ("Table1", "Table2", and so on).

The CollectionChanged event occurs if the table is successfully added to the collection.

The following example adds a DataTable with the given name to the DataTableCollection.

Private Sub AddTable()
    ' Presuming a DataGrid is displaying more than one table, 
    ' get its DataSet.
    Dim thisDataSet As DataSet = _
        CType(DataGrid1.DataSource, DataSet)

    ' Use the Add method to add a new table with a given name.
    Dim table As DataTable = thisDataSet.Tables.Add("NewTable")

    ' Code to add columns and rows not shown here.

End Sub
