Examples

The following examples show how to get and set values using the ItemArray property.

private void CreateRowsWithItemArray()
{
    // Make a DataTable using the function below.
    DataTable dt = MakeTableWithAutoIncrement();
    DataRow relation;
    // Declare the array variable.
    object [] rowArray = new object[2];
    // Create 10 new rows and add to DataRowCollection.
    for(int i = 0; i <10; i++)
    {
        rowArray[0]=null;
        rowArray[1]= "item " + i;
        relation = dt.NewRow();
        relation.ItemArray = rowArray;
        dt.Rows.Add(relation);
    }
    PrintTable(dt);
}

private DataTable MakeTableWithAutoIncrement()
{
    // Make a table with one AutoIncrement column.
    DataTable table = new DataTable("table");
    DataColumn idColumn = new DataColumn("id",
        Type.GetType("System.Int32"));
    idColumn.AutoIncrement = true;
    idColumn.AutoIncrementSeed = 10;
    table.Columns.Add(idColumn);

    DataColumn firstNameColumn = new DataColumn("Item",
        Type.GetType("System.String"));
    table.Columns.Add(firstNameColumn);
    return table;
}

private void PrintTable(DataTable table)
{
    foreach(DataRow row in table.Rows)
    {
        foreach(DataColumn column in table.Columns)
        {
            Console.WriteLine(row[column]);
        }
    }
}

Private Sub CreateRowsWithItemArray()
    ' Make a DataTable using the function below.
    Dim dt As DataTable = MakeTableWithAutoIncrement()
    Dim relation As DataRow

    ' Declare the array variable.
    Dim rowArray(1) As Object

    ' Create 10 new rows and add to DataRowCollection.
    Dim i As Integer
    For i = 0 to 9
       rowArray(0) = DBNull.Value
       rowArray(1)= "item " & i.ToString()
       relation = dt.NewRow()
       relation.ItemArray = rowArray
       dt.Rows.Add(relation)
    Next
    PrintTable(dt)
End Sub
 
Private Function MakeTableWithAutoIncrement() As DataTable
    ' Make a table with one AutoIncrement column.
    Dim table As New DataTable("table")
    Dim idColumn As New DataColumn("id", _
        Type.GetType("System.Int32"))
    idColumn.AutoIncrement = True
    idColumn.AutoIncrementSeed = 10
    table.Columns.Add (idColumn)
    
    Dim firstNameColumn As New DataColumn( _
        "Item", Type.GetType("System.String"))
    table.Columns.Add(firstNameColumn)
    MakeTableWithAutoIncrement = table
End Function
 
Private Sub PrintTable(table As DataTable)
    Dim row As DataRow
    Dim column As DataColumn
    For Each row in table.Rows
       For Each column in table.Columns
          Console.WriteLine(row(column))
       Next
    Next
End Sub

Remarks

You can use this property to set or get values for this row through an array. If you use this property to set values, the array must have the same size and ordering as the column collection. Passing null in the ItemArray indicates that no value was specified.

Users can generate exceptions in the ColumnChanging event or the RowChanging event.
