DataSet() DataSet() DataSet()

Initializes a new instance of the DataSet class.

DataSet(String) DataSet(String) DataSet(String) DataSet(String)

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

DataSet(SerializationInfo, StreamingContext) DataSet(SerializationInfo, StreamingContext) DataSet(SerializationInfo, StreamingContext) DataSet(SerializationInfo, StreamingContext)

Initializes a new instance of a DataSet class that has the given serialization information and context.

DataSet(SerializationInfo, StreamingContext, Boolean) DataSet(SerializationInfo, StreamingContext, Boolean) DataSet(SerializationInfo, StreamingContext, Boolean) DataSet(SerializationInfo, StreamingContext, Boolean)

Initializes a new instance of the DataSet class.

DataSet() DataSet() DataSet()

Initializes a new instance of the DataSet class.

public:
 DataSet();
public DataSet ();
Public Sub New ()

Examples

The following example creates a new DataSet, and adds two DataTable objects to it.

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

    ' 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.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"))
    MakeTable = table
End Function

Remarks

This implementation of the DataSet constructor takes no parameters, and creates a default name, "NewDataSet," for the new instance.

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.

DataSet(String) DataSet(String) DataSet(String) DataSet(String)

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

public:
 DataSet(System::String ^ dataSetName);
public DataSet (string dataSetName);
new System.Data.DataSet : string -> System.Data.DataSet
Public Sub New (dataSetName As String)
Parameters
dataSetName
String String String String

The name of the DataSet.

Examples

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
