我写了一些代码来将数据从外部服务器传输到Hololens。我能够将Hololens连接到服务器。但是我在将数据从服务器发送到Hololens时遇到了问题。每当我调用func handleLongGesture(gesture: UILongPressGestureRecognizer) {
switch(gesture.state) {
case UIGestureRecognizerState.Began:
guard let selectedIndexPath = self.collectionView.indexPathForItemAtPoint(gesture.locationInView(self.collectionView)) else {
break
}
collectionView.beginInteractiveMovementForItemAtIndexPath(selectedIndexPath)
case UIGestureRecognizerState.Changed:
collectionView.updateInteractiveMovementTargetPosition(gesture.locationInView(gesture.view!))
case UIGestureRecognizerState.Ended:
collectionView.endInteractiveMovement()
default:
collectionView.cancelInteractiveMovement()
}
}
功能时，它甚至没有连接（它打印未连接）。
我对ReadData和团结并不熟悉，也无法解决这个问题。
我正在使用c#和DataReader类分别连接和读取数据。函数StreamSocket以Connect()方法与服务器连接，然后我在start()方法中调用ReadData函数，以便在每一帧从服务器获取数据。我附上了我的代码文件。
你能帮助我解决我的问题吗，提前谢谢你。

是否需要异步调用因此我更新了代码，但即使现在也无法正常工作。
2.我正在使用Unity Editor，我已启用所需的设置，我可以连接到服务器。只是我无法传输数据。
3.我使用netcat创建服务器。
我的更新代码
ReadData()答案 0 :(得分：1)
我怀疑你没有启用UWP功能＆＃34; InternetClient＆＃34;这将阻止它实际连接到远程服务器。您没有提到您正在使用的工具链，但如果您在Unity中，请检查Build Settings - ＆gt;发布设置 - ＆gt; Windows应用商店 - ＆gt;发布设置 - ＆gt;能力。如果您在Visual Studio中工作，则可以在项目属性中进行调整。
