The above method does not work if the DataRow status is Detached. This code snippet could be used in such case:
如果 DataRow 状态为 Detached，则上述方法不起作用。在这种情况下可以使用此代码片段：
DataRow dRow = dataTable.NewRow();
//...
DataRowView dRowView = dRow.Table.DefaultView.AddNew();
for (int i = 0; i < dRow.ItemArray.Length; i++)
{
dRowView.Row[i] = dRow[i];
}

Use. It also works if the DataGrid is ordered.
用。如果订购了 DataGrid，它也可以工作。
DataRowView selecRow = dataTable.DefaultView.Cast<DataRowView>().Where(a => a.Row == desRow).FirstOrDefault();
回答by omei
DataRowView selecRow = dataTable.DefaultView.Cast<DataRowView>().FirstOrDefault(a => a.Row == desRow);
works, this is a litte shorter without "where" ;-)
有效，这是一个没有“where”的短一点；-)
