推荐答案

如果您的意思是在 Visual Studio 项目中的文件夹中的项目文件夹，我通常会右键单击文件并将构建操作设置为嵌入式资源".在运行时，您可以像这样从嵌入的资源中读取数据:

If you mean project folders as in the folders in your visual studio project, I usually right click on the files and set the build action to 'Embedded Resource'. At runtime, you can read the data from the embedded resource like so:

// The resource name will correspond to the namespace and path in the file system.
// Have a look at the resources collection in the debugger to figure out the name.
string resourcePath = "assembly namespace" + "path inside project";
Assembly assembly = Assembly.GetExecutingAssembly();
string[] resources = assembly .GetManifestResourceNames();
List<string> files = new List<string>();

if (resource.StartsWith(resourcePath))
{
    StreamReader reader = new StreamReader(assembly.GetManifestResourceStream(resource), Encoding.Default);
    files.Add(reader.ReadToEnd());
}

要读取图像，您需要这样的东西来读取流:

To read the images you would need something like this to read the stream:

    public static byte[] ReadAllBytes(Stream input)
    {
        byte[] buffer = new byte[32 * 1024];

        using (MemoryStream ms = new MemoryStream())
        {
            int read;

            while ((read = input.Read(buffer, 0, buffer.Length)) > 0)
            {
                ms.Write(buffer, 0, read);
            }

            return ms.ToArray();
        }
    }
