Unity Texture和Base64互转_unity base64转texture

一、TextureToBase64

	/// <summary>
	/// TextureToBase64普通转换
	/// </summary>
	/// <param name="texture2D"></param>
	/// <returns></returns>
	public static string TextureToBase64(Texture2D texture2D)
	{
		byte[] imageData = texture2D.EncodeToJPG();
		string baser64 = Convert.ToBase64String(imageData);
		return baser64;
	}

    /// <summary>
    /// 图片文件普通转换
    /// </summary>
    /// <param name="filePath"></param>
    /// <returns></returns>
    public static string TextureFileBase64(string filePath)
    {
        FileStream filestream = new FileStream(filePath, FileMode.Open);
        byte[] arr = new byte[filestream.Length];
        filestream.Read(arr, 0, (int)filestream.Length);
        string baser64 = Convert.ToBase64String(arr);
        filestream.Close();
        return baser64;
    }

	/// <summary>

	/// <param name="texture2D"></param>
	/// <returns></returns>
	public static string TextureToBase64_Prefixing(Texture2D texture2D)
	{
		return "data:image/jpeg;base64," + TextureToBase64(texture2D);

二、Base64ToTexture

    public static Texture2D Base64ToTexture(string imageData)
    {
        Texture2D pic = new Texture2D(190, 190, TextureFormat.RGBA32, false);
        byte[] data = System.Convert.FromBase64String(imageData);
        pic.LoadImage(data);
        return pic;
    }
