Load Texture2D in c#

www methods changed at each Unity version.

I used from Unity 5.6.3, so summary with this function.

IEnumerator LoadTexture (string filePath) {

    string url;

    if (filePath.StartsWith ("http")) {

        // from WEB

        url = filePath;

    } else {

        // from local

#if UNITY_ANDROID

        url = "file://" + Uri.EscapeUriString (filePath);

#elif UNITY_IOS

        url = "file://" + filePath;

#endif

    }

#if UNITY_2017_2_OR_NEWER

    using (UnityWebRequest www = UnityWebRequestTexture.GetTexture (url)) {

          yield return www.SendWebRequest ();

         if (www.isNetworkError) {

             Debug.Log ("www.error: " + www.error);

         } else {

              Texture2D loadedTexture = DownloadHandlerTexture.GetContent (www);

#elif UNITY_2017_1_OR_NEWER

    using (UnityWebRequest www = UnityWebRequestTexture.GetTexture (url)) {

        yield return www.Send ();

        if (www.isNetworkError) {

            Debug.Log ("www.error: " + www.error);

        } else {

             Texture2D loadedTexture = DownloadHandlerTexture.GetContent (www);

#elif UNITY_5_6_OR_NEWER

    using (WWW www = new WWW (url)) {

         yield return www;

        if (www.error != null) {

            Debug.Log ("www.error: " + www.error);

        } else {

            Texture2D loadedTexture = www.texture;

#endif

            // Do action as you want.

        }

    }

}
