VS 2010将非GUI类文件设置为Component

Question

我对Visual Studio 2010已经发生了很长一段时间的烦恼.我有一个类文件,我将VS保存为类型"组件",我无法辨别.如果我忘记并尝试打开文件,它会查找不存在的设计器.

我查看了Google并发现了VS 2005的一些类似问题,但问题似乎与从GUI组件类(listbox,combobox等)派生有关.这个课不这样做.

该文件是GpsUtilities.cs.它如下,出现在的csproj文件SubType中Component.没有其他对该文件的引用,即没有任何声称它DependentUpon.

<Compile Include="Utilities\GpsUtilities.cs">
  <SubType>Component</SubType>
</Compile>

即使我删除SubType标记,即使我明确地将其设置为Code替代Component,它仍然将其保存为SubType的Component.

这是类结构(所有代码都被删除).正如我所说,它不会继承,甚至不导入与GUI相关的任何名称空间.

        public bool IsCloseTo(GpsPositionData otherPoint, double tolerance = 0.0001) {}

        public GpsPositionData(DateTime time, double latitude, double longitude, GpsFixQuality fixQuality, int numberOfSatellites, double hdop, double altitude, double geodialSeparation, int ageOfDgps, string dgpsRefStationId){}

提前致谢.

Answer 1

如果要将所有类保留在一个文件中,可以使用该类[System.ComponentModel.DesignerCategory("Code")]上的属性GPSPort来覆盖默认行为. 详细信息请注意,即使您有语句,您也必须使用完全限定属性,using System.ComponentModel否则VS将忽略它.

Answer 2

猜测一下,我会说这是由于你的GPSPort课程延伸SerialPort而来的Component.尝试删除它(或将其移动到单独的文件中),看看它是否解决了问题.
