속성 값

DataRowState

DataRowState 값 중 하나입니다.One of the DataRowState values.

예제

다음 예에서는 먼저 DataTable 하나의 열이 있는 새를 만든 다음 단일을 만듭니다 DataRow .The following example first creates a new DataTable with one column, and then creates a single DataRow. DataRow가 생성, 추가, 수정 및 삭제 되 면 RowState 이 인쇄 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

의 값은 RowState 두 가지 요인, 즉 행에서 수행 된 작업의 종류 및 AcceptChanges 가에서 호출 되었는지 여부에 따라 달라 집니다 DataRow .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.
