DataTable.AcceptChanges 메서드

정의

AcceptChanges()가 마지막으로 호출된 이후 이 테이블에서 변경된 내용을 모두 커밋합니다.Commits all the changes made to this table since the last time AcceptChanges() was called.

public:
 void AcceptChanges();
public void AcceptChanges ();
member this.AcceptChanges : unit -> unit
Public Sub AcceptChanges ()

예제

다음 예제에서는 각 테이블의 오류를 테스트합니다.The following example tests each table for errors. 테이블의 오류를 정의 되지 않은 함수에 전달 하 여 조정할 수 있는 경우 AcceptChanges가 호출 됩니다. 그렇지 않으면 RejectChanges가 호출 됩니다.If the table's errors can be reconciled (by passing it to an undefined function), AcceptChanges is called; otherwise, RejectChanges is called.

   private void AcceptOrReject(DataTable table)
   {
       // If there are errors, try to reconcile.
       if(table.HasErrors)
       { 
           if(Reconcile(table))
           {
               // Fixed all errors.
               table.AcceptChanges();
           }
           else
           {
               // Couldn'table fix all errors.
               table.RejectChanges();
           }
       }
       else
       {
           // If no errors, AcceptChanges.
           table.AcceptChanges();
       }
   }

   private bool Reconcile(DataTable thisTable)
   {
       foreach(DataRow row in thisTable.Rows)
       {
           //Insert code to try to reconcile error.

           // If there are still errors return immediately
           // since the caller rejects all changes upon error.
           if(row.HasErrors)
               return false;
       }
       return true;
   }
Private Sub AcceptOrReject(table As DataTable)
    ' If there are errors, try to reconcile.
        If (table.HasErrors) Then
            If (Reconcile(table)) Then
                ' Fixed all errors.
                table.AcceptChanges()
            Else
                ' Couldn'table fix all errors.
                table.RejectChanges()
            End If
        Else
            ' If no errors, AcceptChanges.
            table.AcceptChanges()
        End If
 End Sub
 
Private Function Reconcile(thisTable As DataTable) As Boolean
    Dim row As DataRow
    For Each row in thisTable.Rows
       'Insert code to try to reconcile error.

       ' If there are still errors return immediately
       ' since the caller rejects all changes upon error.
       If row.HasErrors Then
           Reconcile = False
           Exit Function
       End If
    Next row
    Reconcile = True
 End Function

설명

AcceptChanges가 호출 되 면 편집 모드의 모든 DataRow 개체가 성공적으로 편집을 종료 합니다.When AcceptChanges is called, any DataRow object still in edit mode successfully ends its edits. DataRowState 또한 모든 AddedModified 행이 Unchanged되 고 Deleted 행이 제거 됩니다.The DataRowState also changes: all Added and Modified rows become Unchanged, and Deleted rows are removed.

DbDataAdapter.Update 메서드를 사용 하 여 DataSet를 업데이트 하려고 시도한 후에는 일반적으로 DataTable에서 AcceptChanges 메서드가 호출 됩니다.The AcceptChanges method is generally called on a DataTable after you attempt to update the DataSet using the DbDataAdapter.Update method.
