SqlCommandBuilder.GetInsertCommand();抛出异常

Question

打电话时出现以下异常

SqlCommandBuilder.GetInsertCommand()

System.InvalidOperationException：'当分配给命令的连接处于挂起的本地事务中时，ExecuteReader 要求该命令具有事务。命令的 Transaction 属性尚未初始化。'

我在 SqlCommandBuilder.GetInsertCommand() 之前调用 SqlConnection.BeginTrans()

Answer 1

我通过将

SqlTransaciton

 分配给 

SqlDataAdapter.SelectCommand 解决了这个问题

  using (SqlCommandBuilder builder = new SqlCommandBuilder(_adapter))
    {
        _adapter.SelectCommand.Transaction = Database.transaction; // This fix problem
        _adapter.InsertCommand = builder.GetInsertCommand(); // No exception now
        _adapter.UpdateCommand = builder.GetUpdateCommand(); // No exception now
        _adapter.DeleteCommand = builder.GetDeleteCommand(); // No exception now

        _adapter.InsertCommand.Transaction = Database.transaction;
        _adapter.UpdateCommand.Transaction = Database.transaction;
        _adapter.DeleteCommand.Transaction = Database.transaction;
        _adapter.Update(this);
    }
