SqlDataAdapter更新问题 [英] SqlDataAdapter update problem

问题描述

SqlDataAdapter dataAdpater;
SqlCommandBuilder commandBuilder;
this.QCDataAdapterDictionary.TryGetValue(table.TableName, out dataAdpater);
this.QCCommandBuilderDictionary.TryGetValue(table.TableName, out commandBuilder);
if (dataAdpater != null && dataAdpater != null)
    {
        dataAdpater.InsertCommand = commandBuilder.GetInsertCommand();

        dataAdpater.Update(table);
        table.AcceptChanges();
    }

表是从DB加载的，它已经插入并删除了一些记录，

当我执行上面的程序时，它会执行delete命令，但dataAdpater.DeleteCommand设置为null。非常混淆......



谢谢〜

when i execute above program, it will execute delete command, but the dataAdpater.DeleteCommand set null. very confuse...

thanks~
