DataTableCollection.Add Method (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)

'Declaration
Public Function Add ( _
	name As String _
) As DataTable

Parameters

name
Type: System.String

The name to give the created DataTable.

Return Value

Type: System.Data.DataTable
The newly created DataTable.

ExceptionCondition
DuplicateNameException

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

If either Nothing 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.

    Console.WriteLine(table.TableName)
    Console.WriteLine(thisDataSet.Tables.Count.ToString())
End Sub
