Question

我目前正在使用我的 Raspberry Pi Grove 传感器和 Windows IoT 进行试验。我正在尝试启动最简单的程序，但收到错误消息。

代码看起来是这样的：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net.Http;
using Windows.ApplicationModel.Background;
using GrovePi;
using GrovePi.I2CDevices;
using GrovePi.Sensors;
using GrovePi.Common;

// The Background Application template is documented at http://go.microsoft.com/fwlink/?LinkID=533884&clcid=0x409

namespace IoT_THS_final
{
    public sealed class StartupTask : IBackgroundTask
    {
        IRgbLcdDisplay LCDDisplay;
        public void Run(IBackgroundTaskInstance taskInstance)
        {
            LCDDisplay = DeviceFactory.Build.RgbLcdDisplay();

            for (int i = 1; i < 1000; i++)
            {
                i = i + 50;

                LCDDisplay.SetBacklightRgb(BitConverter.GetBytes(i)[0], BitConverter.GetBytes(i)[0], BitConverter.GetBytes(i)[0]);
                LCDDisplay.SetText("Hello");
                System.Threading.Tasks.Task.Delay(1000).Wait();
            }
        }
    }
}

出现错误：

Error Validation Error. error C00CE169: App manifest validation error: The app manifest must be valid as per schema: Line 10, Column 13, Reason: 'IoT_THS_final-uwp' conflicts with pattern declaration '[-.A-Za-z0-9]+'.

Answer 1

阅读错误日志时，我们可以看到以下内容：

Reason: 'IoT_THS_final-uwp' verstößt gegen pattern-Einschränkung von '[-.A-Za-z0-9]+'

这意味着 IoT_THS_final-uwp 包含不允许的字符。允许的字符为 [-.A-Za-z0-9]+。这意味着您需要从名称中删除下划线 (_)，这应该可以解决您的问题。（也感谢评论中的@yW0K5o）
