DataSet Constructor (String)

Initializes a new instance of a DataSet class with the given name.

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

public DataSet(
	string dataSetName
)

Parameters

dataSetName
Type: System.String

The name of the DataSet.

A name for the DataSet is required to ensure that the XML representation of the DataSet always has a name for the document element, which is the highest level element in a schema definition.

The following example creates a new DataSet, to which two DataTable objects are added.

Private Sub CreateDataSet()
    Dim  dataSet As DataSet = New DataSet("aNewDataSet")

    ' Create two DataTable objects using a function. 
    Dim table1 As DataTable = MakeTable("idTable1", "thing1")
    Dim table2 As DataTable = MakeTable("idTable2", "thing2")

    dataSet.Tables.Add(table1)
    dataSet.Tables.Add(table2)
    Console.WriteLine(dataSet.DataSetName, dataSet.Tables.Count)
End Sub 


Private Function MakeTable(c1Name As String, c2Name As String) _
    As DataTable
    Dim table As New DataTable

    ' Add two DataColumns 
    Dim column As DataColumn = New DataColumn( _
        c1Name, System.Type.GetType("System.Integer"))
    table.Columns.Add(column)
    column = New DataColumn(c2Name, _
        System.Type.GetType("System.String"))
    table.Columns.Add(column)
    MakeTable = table
End Function
