Question

我正在尝试设置和构建https://resources.samsungdevelopers.com/Gear_VR/030_Create_VR_App_or_Game_Using_a_Game_Engine/Exercise_2%3A_Create_a_Splash_Screen/Step_7%3A_Build_and_Run_the_Application

当我尝试构建应用程序时，它会抛出以下错误： Assets / Workshop / Scripts / TextureLoader.cs（114,31）：错误CS1105：`TextureLoader.GetFilesWithExtensions（此DirectoryInfo，params string []）'：扩展方法必须声明为static

// Gets the list of files in the directory by extention and filters for our specified ones (images)
public IEnumerable<FileInfo> GetFilesWithExtensions (this DirectoryInfo dir, params string[] extensions) {
    IEnumerable<FileInfo> files = dir.GetFiles();
    return files.Where(f => extensions.Contains(f.Extension));
}

public bool isFinishedLoadingFirstTexture() {
    return mFinishedFirstTexture;
}

我已将其更改为标题中的公共静态类。

Answer 1

我为了制作扩展方法，该类必须是public和static。

该功能也必须是public和static。你错过了这部分。

public static class TextureLoader
{
    public static IEnumerable<FileInfo> GetFilesWithExtensions(this DirectoryInfo dir, params string[] extensions)
    {
        IEnumerable<FileInfo> files = dir.GetFiles();
        return files.Where(f => extensions.Contains(f.Extension));
    }
}

Answer 2

以这种方式修改代码，错误将消失

private IEnumerable<FileInfo> GetFilesWithExtensions(DirectoryInfo dir, string[] extensions)
{
    IEnumerable<FileInfo> files = dir.GetFiles();
    return files.Where(f => extensions.Contains(f.Extension));
}
