UWP網絡連接中用到異步處理接收數據的方法
/// <summary>
/// 開始接收數據
/// </summary>
public void StartRecive()
{
DataReaderLoadOperation drlo = tcpinput.LoadAsync((uint)buffer.Length);
drlo.Completed = new AsyncOperationCompletedHandler<uint>(DataReadHandler);
}
/// <summary>
/// 用.net core實現接收信息
/// </summary>
/// <param name="operation"></param>
/// <param name="status"></param>
public void DataReadHandler(IAsyncOperation<uint> operation, AsyncStatus status)
{
uint dd1;
int iii = 0;
int length;
try
{
if (status == AsyncStatus.Completed)
{
length = (int)operation.GetResults();
byte[] data = new byte[length];
tcpinput.ReadBytes(data);
Buffer_Manager(data);
DataReaderLoadOperation drlo = tcpinput.LoadAsync((uint)buffer.Length);
drlo.Completed = new AsyncOperationCompletedHandler<uint>(DataReadHandler);
}
else
{
}
}
catch (Exception ex)
{
return;
}
}
其中當遠程關閉連接或關閉程序時，status的值為error，而不是觸發異常，與.net中socket的機制不一樣
