read/write Enable 无法在项目运行时更改

Answer 1

/// <summary>
/// 以IO方式进行加载
/// </summary>
private void LoadByIO()
{
    string ImagePath = string.Format("{0}/{1}", Application.streamingAssetsPath, "Test.jpg");
    Debug.LogFormat("ImagePath:{0}", ImagePath);
    //创建文件读取流
    FileStream fileStream = new FileStream(ImagePath, FileMode.Open, FileAccess.Read);
    fileStream.Seek(0, SeekOrigin.Begin);
    //创建文件长度缓冲区
    byte[] bytes = new byte[fileStream.Length];
    //读取文件
    fileStream.Read(bytes, 0, (int)fileStream.Length);
    //释放文件读取流
    fileStream.Close();
    fileStream.Dispose();
    fileStream = null;

    //创建Texture
    int width = 300;
    int height = 372;
    Texture2D texture = new Texture2D(width, height);
    texture.LoadImage(bytes);

    Color[] colors = texture.GetPixels();
    Debug.LogFormat("pixels:{0}", colors.Length);

}
    看看能不能帮到你
