예제

다음 예제에서는 DataTable, 두 개 더한 DataColumn 개체는 테이블의 스키마를 확인 하 고 여러 만듭니다 DataRow 사용 하 여 개체를 NewRow 메서드.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 개체에 추가 됩니다 합니다 DataRowCollection 사용 하 여를 Add 메서드.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.

       }

       // Create a DataView using the DataTable.

       dataGrid1.DataSource = view;
   }

    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.

설명

사용 해야 합니다는 NewRow 새로 만들기 방법 DataRow 와 동일한 스키마를 사용 하 여 개체를 DataTable입니다.You must use the NewRow method to create new DataRow objects with the same schema as the DataTable. 만든 후는 DataRow를 추가할 수 있습니다는 DataRowCollection을 통해 합니다 DataTable 개체의 Rows 속성.After creating a DataRow, you can add it to the DataRowCollection, through the DataTable object's Rows property. 사용 하는 경우 NewRow 새 행을 만들려면 행에 추가 하거나 삭제 해야 데이터 테이블에서 호출 하기 전에 Clear입니다.When you use NewRow to create new rows, the rows must be added to or deleted from the data table before you call Clear.
