预计读取4个头字节但仅接收0

我编写了一个Windows服务，它使用SSH（Secure Shell）将数据从CSV文件复制到PhpMyAdmin在线数据库。

连接打开时出现错误触发，

MySql.Data.MySqlClient.MySqlProtocolException HResult=0x80131509 Message=Packet received out-of-order. Expected 2; got 1. Source=mscorlib StackTrace: at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) 

作为解决方案，我决定保持当前线程并在连接打开之前添加以下行。

 Task.Delay(TimeSpan.FromMilliseconds(10000)).Wait(); 

不幸的是，这会导致另一个错误，

 MySql.Data.MySqlClient.MySqlException HResult=0x80004005 Message=Failed to read the result set. Source=MySqlConnector StackTrace: Inner Exception 1: EndOfStreamException: Expected to read 4 header bytes but only received 0. 

当我随机改变线程保持的时间值时，上述2个错误彼此不同。

相关代码块：

  Public void insert(string connString){ using (var conn = new MySqlConnection(connString)) { Task.Delay(TimeSpan.FromMilliseconds(10000)).Wait(); conn.Open(); using(var reader = new StreamReader(@"C:\Users\Admin\source\Bargstedt.csv")) { while (!reader.EndOfStream) { var line = reader.ReadLine(); var values = line.Split(','); string querynew = "INSERT INTO jobs" + "(nJobNumber,strClientReference,datPromisedDelivery)" + "VALUES (@jobNo, @strClientName, @strClientReference)"; using (var cmd = new MySqlCommand()) { cmd.Connection = conn; cmd.CommandText= querynew; cmd.Parameters.AddWithValue("jobNo", values[0]); cmd.Parameters.AddWithValue("strClientName", values[1]); cmd.Parameters.AddWithValue("strClientReference",values[2]); cmd.ExecuteNonQuery(); } } } } } 

有任何建议如何修复此exception？
