UWP判斷文件是否存在 ? ?http://blog.csdn.net/lindexi_gd/article/details/51387901

UWP網(wǎng)絡(luò)連接中用到異步處理接收數(shù)據(jù)的方法

/// <summary>
/// 開(kāi)始接收數(shù)據(jù)
/// </summary>
public void StartRecive()
{

DataReaderLoadOperation drlo = tcpinput.LoadAsync((uint)buffer.Length);
drlo.Completed = new AsyncOperationCompletedHandler<uint>(DataReadHandler);
}

/// <summary>
/// 用.net core實(shí)現(xiàn)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(dāng)遠(yuǎn)程關(guān)閉連接或關(guān)閉程序時(shí)，status的值為error，而不是觸發(fā)異常，與.net中socket的機(jī)制不一樣
