从DataReader读取数据时出现OutOfMemoryException

这是这种情况：我正在建立TCP连接（对我自己）以字符串格式发送一些数据。创建一个连接，发送数据，然后立即关闭连接（我不想同步等待数据）。在发送字符串之前，我将其长度（data.Length）附加在字符串的前面，因此我知道接收到该字符串时要读取多少数据。我正在StreamSocketListener侦听来自TCP连接的传入数据，并制作了一些“帮助程序”类，以简化外部环境。该类被实例化一次，并Start调用该方法以开始侦听连接。就是这种情况。当我发送数据（给自己，但这没关系）时，我System.OutOfMemoryException在方法中得到了StreamReadLine。

对我来说，为什么发生这种情况不是很明显，所以这就是为什么我在这里。我希望有人以前已经处理过这个问题，并且知道是什么问题。
