Question

我使用vs 2017和Windows 7。我已经按照以下步骤安装了32feet.NET：Looking to write Bluetooth 'hcitool' equivelant in Windows。

但是我得到了错误：

找不到类型或名称空间名称'BluetoothAddress'

找不到类型或名称空间名称'BluetoothClient'

找不到类型或名称空间名称'BluetoothSecurity'

找不到类型或名称空间名称'BluetoothDeviceInfo'

找不到类型或名称空间名称'ServiceRecord'

我已经成功安装了InTheHand.Devices.Bluetooth，并且using语句中没有警告，因此成功引用了命名空间。

Answer 1

尝试将以下名称空间添加到您的代码中：

using InTheHand.Net;
using InTheHand.Net.Sockets;
using InTheHand.Net.Bluetooth;

Answer 2

BluetoothAddress 位于 32feet.NET nuget程序包中。

您正在使用InTheHand的预览版，其中缺少 BluetoothAddress ， BluetoothRadio ， BluetoothDeviceInfo 等。我认为您引用的是 32feet.NET 的Wiki，它是旧版nuget程序包。如果安装 32feet.NET v3.5.0.0 ，则会找到所有缺少的绑定。

添加 32feet.NET 并进行以下更改：

var dev = new BluetoothDevice(); 
//this becomes this:
var dev = new BluetoothDeviceInfo(_searchAddress);

它将成功编译。

找不到类型或名称空间名称“ BluetoothAddress”
