MySqlConnector.MySqlException (0x80004005): Failed to read the result set.
---> MySqlConnector.MySqlEndOfStreamException: An incomplete response was received from the server
at MySqlConnector.Protocol.Serialization.ProtocolUtility.ReadPayloadAsync(BufferedByteReader bufferedByteReader, IByteHandler byteHandler, Func`1 getNextSequenceNumber, ArraySegmentHolder`1 previousPayloads, ProtocolErrorBehavior protocolErrorBehavior, IOBehavior ioBehavior) in /_/src/MySqlConnector/Protocol/Serialization/ProtocolUtility.cs:line 424
相关Mysqlconnector的代码如下：
public static async ValueTask<ArraySegment<byte>> ReadPayloadAsync(BufferedByteReader bufferedByteReader, IByteHandler byteHandler, Func<int> getNextSequenceNumber, ArraySegmentHolder<byte> previousPayloads, ProtocolErrorBehavior protocolErrorBehavior, IOBehavior ioBehavior)
{
previousPayloads.Clear();
while (true)
{
// read the packet header
var headerBytes = await bufferedByteReader.ReadBytesAsync(byteHandler, 4, ioBehavior).ConfigureAwait(false);
if (headerBytes.Count < 4)
{
return protocolErrorBehavior == ProtocolErrorBehavior.Ignore ? default :
throw new MySqlEndOfStreamException(4, headerBytes.Count);
}
