DataTable RowChanged如何获取前一个Row值？

Question

我有一个DataTable.当行发生变化时,我需要得到这一行,它是以前的值(DataRow).我怎么才能得到它？

Answer 1

您应该订阅该ColumnChanged事件,这样您就可以看到之前和当前的值.

例:

//code to wire up the handler
custTable.ColumnChanged += new DataColumnChangeEventHandler(Column_Changed);

//code for the event
private static void Column_Changed(object sender, DataColumnChangeEventArgs e )
{
    Console.WriteLine("Column_Changed Event: name={0}; Column={1}; original name={2}", 
        e.Row["name"], e.Column.ColumnName, e.Row["name", DataRowVersion.Original]);
}
