用BeginExecuteNonQuery编写异步web服务？

Question

我有一个sql存储proc将启动批量插入，我不需要我的web服务被挂断，等待响应。我的问题是：我将如何在这种情况下实现BeginExecuteNonQuery？

Answer 1

我认为这可能让你开始：

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(); 
    } 
}
