DataTableCollection.Add Method ()

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

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

public DataTable Add ()
public DataTable Add ()
public function Add () : DataTable
Not applicable.

Return Value

The newly created DataTable.

Because no name is specified, the DataTable is created by using a default name, relative to its order of addition. The default name is "Table1."

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

The following example adds three new DataTable objects to the DataTableCollection using the Add method without arguments.

private void AddTables()
{
    // Presuming a DataGrid is displaying more than one table, 
    // get its DataSet.
    DataSet thisDataSet = (DataSet)DataGrid1.DataSource;

    for (int i = 0; i < 3; i++)
        thisDataSet.Tables.Add();
    Console.WriteLine(thisDataSet.Tables.Count.ToString() 
        + " tables");
    foreach (DataTable table in thisDataSet.Tables)
        Console.WriteLine(table.TableName);
}
