DataTable.NewRow Method

Definition

테이블과 동일한 스키마를 갖는 새 DataRow를 만듭니다.Creates a new DataRow with the same schema as the table.

public:
 System::Data::DataRow ^ NewRow();
public System.Data.DataRow NewRow ();
member this.NewRow : unit -> System.Data.DataRow
Public Function NewRow () As DataRow

Returns

DataRow

DataRow과 동일한 스키마를 갖는 DataTable를 반환합니다.A DataRow with the same schema as the DataTable.

Examples

다음 예에서는 DataTable를 만들고, 테이블의 스키마를 결정 하는 두 개의 DataColumn 개체를 추가 하 고, NewRow 메서드를 사용 하 여 여러 개의 DataRow 개체를 새로 만듭니다.The following example creates a DataTable, adds two DataColumn objects that determine the table's schema, and creates several new DataRow objects using the NewRow method. 이러한 DataRow 개체는 Add 메서드를 사용 하 여 DataRowCollection에 추가 됩니다.Those DataRow objects are then added to the DataRowCollection using the Add method.

private void MakeDataTableAndDisplay()
{
    // Create new DataTable and DataSource objects.
    DataTable table = new DataTable();

    // Declare DataColumn and DataRow variables.
    DataColumn column;
    DataRow row;
    DataView view;

    // Create new DataColumn, set DataType, ColumnName and add to DataTable.
    column = new DataColumn();
    column.DataType = System.Type.GetType("System.Int32");
    column.ColumnName = "id";
    table.Columns.Add(column);

    // Create second column.
    column = new DataColumn();
    column.DataType = Type.GetType("System.String");
    column.ColumnName = "item";
    table.Columns.Add(column);

    // Create new DataRow objects and add to DataTable.
    for(int i = 0; i < 10; i++)
    {
        row = table.NewRow();
        row["id"] = i;
        row["item"] = "item " + i.ToString();
        table.Rows.Add(row);
    }

    // Create a DataView using the DataTable.
    view = new DataView(table);

    // Set a DataGrid control's DataSource to the DataView.
    dataGrid1.DataSource = view;
}
Private Sub MakeDataTableAndDisplay()
    ' Create new DataTable and DataSource objects.
    Dim table As New DataTable()

    ' Declare DataColumn and DataRow variables.
    Dim column As DataColumn 
    Dim row As DataRow 
    Dim view As DataView 

    ' Create new DataColumn, set DataType, ColumnName and add to DataTable.    
    column = New DataColumn()
    column.DataType = System.Type.GetType("System.Int32")
    column.ColumnName = "id"
    table.Columns.Add(column)
 
    ' Create second column.
    column = New DataColumn()
    column.DataType = Type.GetType("System.String")
    column.ColumnName = "item"
    table.Columns.Add(column)
 
    ' Create new DataRow objects and add to DataTable.    
    Dim i As Integer
    For i = 0 to 9 
       row = table.NewRow()
       row("id") = i
       row("item") = "item " & i
       table.Rows.Add(row)
    Next
    ' Create a DataView using the DataTable.
    view = New DataView(table)

    ' Set a DataGrid control's DataSource to the DataView.
    DataGrid1.DataSource = view
End Sub

Remarks

NewRow 메서드를 사용 하 여 DataTable와 동일한 스키마를 사용 하 여 새 DataRow 개체를 만들어야 합니다.You must use the NewRow method to create new DataRow objects with the same schema as the DataTable. DataRow를 만든 후에 DataTable 개체의 Rows 속성을 통해 DataRowCollection에 추가할 수 있습니다.After creating a DataRow, you can add it to the DataRowCollection, through the DataTable object's Rows property. NewRow를 사용 하 여 새 행을 만드는 경우 Clear를 호출 하기 전에 데이터 테이블에서 행을 추가 하거나 삭제 해야 합니다.When you use NewRow to create new rows, the rows must be added to or deleted from the data table before you call Clear.
