使用BeginExecuteNonQuery编写异步Web服务？

Question

我有一个sql存储过程将启动批量插入，我不需要挂起我的web服务，等待响应。我的问题是：如何在此上下文中实现BeginExecuteNonQuery？

Answer 1

我认为这可以让你开始：

private void ExecuteCommandAsync(string sql)
{
   SqlConnection conn = new SqlConnection(connectString + "Async=true;");
   SqlCommand cmd = conn.CreateCommand();
   cmd.CommandText = sql;
   conn.Open();
   cmd.BeginExecuteNonQuery(new AsyncCallback(AsyncCommandCompletionCallback), cmd);
}

private void AsyncCommandCompletionCallback(IAsyncResult result)
{
   SqlCommand cmd = null;
   try
   {
       cmd = (SqlCommand)result.AsyncState;
       cmd.EndExecuteNonQuery(result);

       // Do some more work here...
   }
   catch (Exception ex)
   {
       // Handle errors here
   }
   finally
   {
       cmd.Connection.Close();
       cmd.Dispose();
   }
}
