예제

다음 예제에서는 먼저 새로 만듭니다 DataTable 하나의 열이 있는 단일 다음 만들고 DataRow합니다.The following example first creates a new DataTable with one column, and then creates a single DataRow. DataRow 는 생성, 추가, 수정 및 삭제, 해당 RowState 출력 됩니다.As the DataRow is created, added, modified, and deleted, its RowState is printed.

   private void DemonstrateRowState()
   {
       // Run a function to create a DataTable with one column.
       DataTable table = MakeTable();
       DataRow row;

       // Create a new DataRow.
       row = table.NewRow();
       // Detached row.
       Console.WriteLine("New Row " + row.RowState);

       table.Rows.Add(row);
       // New row.
       Console.WriteLine("AddRow " + row.RowState);

       table.AcceptChanges();
       // Unchanged row.
       Console.WriteLine("AcceptChanges " + row.RowState);

       row["FirstName"] = "Scott";
       // Modified row.
       Console.WriteLine("Modified " + row.RowState);

       row.Delete();
       // Deleted row.
       Console.WriteLine("Deleted " + row.RowState);
   }

   private DataTable MakeTable()
   {
       // Make a simple table with one column.
       DataTable table = new DataTable("table");
       DataColumn dcFirstName = new DataColumn(
           "FirstName", Type.GetType("System.String"));
       table.Columns.Add(dcFirstName);
       return table;
   }
Private Sub DemonstrateRowState()
    ' Run a function to create a DataTable with one column.
    Dim table As DataTable = MakeTable()
    Dim row As DataRow 
 
    ' Create a new DataRow.
    row = table.NewRow()
    ' Detached row.
    Console.WriteLine("New Row " & row.RowState)
 
    table.Rows.Add(row)
    ' New row.
    Console.WriteLine("AddRow " & row.RowState)
 
    table.AcceptChanges()
    ' Unchanged row.
    Console.WriteLine("AcceptChanges " & row.RowState)
 
    row("FirstName") = "Scott"
    ' Modified row.
    Console.WriteLine("Modified " & row.RowState)
 
    row.Delete()
    ' Deleted row.
    Console.WriteLine("Deleted " & row.RowState)
 End Sub
 
 Private Function MakeTable() As DataTable
    ' Make a simple table with one column.
    Dim table As New DataTable("table")
    Dim dcFirstName As New DataColumn( _
        "FirstName", Type.GetType("System.String"))
    table.Columns.Add(dcFirstName)
    MakeTable = table
 End Function

설명

값을 RowState 두 가지 요인에 따라 달라 집니다: 행에서 수행 된 작업의 종류 여부에 관계 없이 AcceptChanges 에서 호출한는 DataRow합니다.The value of the RowState depends on two factors: the kind of operation has been performed on the row, and whether AcceptChanges has been called on the DataRow.
