[英]Raspberry Pi, Grove, Windows IoT, C#
I am currently experimenting with my Raspberry Pi with Grove sensors and Windows IoT.我目前正在用 Grove 传感器和 Windows IoT 试验我的 Raspberry Pi。 I am trying to launch the simpliest program but I recieve an error.我正在尝试启动最简单的程序,但收到错误消息。
The code looks this way:代码如下所示:
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();
}
}
}
}
and there is an error:并且有一个错误:
Error Validation Error.错误验证错误。 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]+'.错误 C00CE169:应用程序清单验证错误:应用程序清单必须按照架构有效:第 10 行,第 13 列,原因:“IoT_THS_final-uwp”与模式声明“[-.A-Za-z0-9]+”冲突。 Analysis from attribute 'Name' with value 'IoT_THS_final-uwp' failed.对值为“IoT_THS_final-uwp”的属性“Name”的分析失败。 IoT THS final C:\\Users\\k39540\\Desktop\\IoT THS final\\IoT THS final\\bin\\ARM\\Debug\\AppxManifest.xml IoT THS final C:\\Users\\k39540\\Desktop\\IoT THS final\\IoT THS final\\bin\\ARM\\Debug\\AppxManifest.xml

When reading the error log, we can see the following:在读取错误日志时,我们可以看到以下内容:
Reason: 'IoT_THS_final-uwp' verstößt gegen pattern-Einschränkung von '[-.A-Za-z0-9]+'原因:'IoT_THS_final-uwp' verstößt gegen pattern-Einschränkung von '[-.A-Za-z0-9]+'
This means that IoT_THS_final-uwp
contains characters which are not allowed.这意味着IoT_THS_final-uwp
包含不允许的字符。 The characters that are allowed are [-.A-Za-z0-9]+
.允许的字符是[-.A-Za-z0-9]+
。 This means you need to remove the underscore ( _
) from the name, which should fix your issue.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。 (Thanks to @yW0K5o in the comments as well) (也感谢评论中的@yW0K5o)
