Unity3D: C# replacement for the python version of PostprocessBuildPlayer

PostprocessBuildPlayer.cs

using UnityEngine;
using System.Collections;
using UnityEditor;
using UnityEditor.Callbacks;
using System.IO;

public class PostprocessBuildPlayer : ScriptableObject {

  [PostProcessBuild]
  static void OnPostprocessBuildPlayer(BuildTarget target, string buildPath) {
    string editorPath = Path.GetFullPath(Path.GetDirectoryName(AssetDatabase.GetAssetPath(MonoScript.FromScriptableObject(ScriptableObject.CreateInstance<PostprocessBuildPlayer>()))));

    if (!Directory.Exists(editorPath)) {
      Debug.LogError("No directory at: " + editorPath);
      return;
    }

    if (!Directory.Exists(buildPath)) {
      Debug.LogError("No directory at: " + buildPath);
      return;
    }

    var files = Directory.GetFiles(editorPath, "*.*", SearchOption.TopDirectoryOnly);

    files = System.Array.FindAll<string>(files, (x) => {
      var name = Path.GetFileName(x).ToLower();

      return name.StartsWith("postprocessbuildplayer_") && !name.EndsWith("meta");
    });

    if (files.Length == 0) {
      Debug.LogError("No postprocess scripts at: " + editorPath);
      return;
    }

    var args = new string[] {
      buildPath,
      target.ToString()
    };

    foreach (var file in files) {
      Debug.Log("executing: " + file);

      using (var process = new System.Diagnostics.Process()) {
        process.StartInfo.FileName = file;
        process.StartInfo.Arguments = string.Join(" ", args);
        process.StartInfo.RedirectStandardError = true;
        process.StartInfo.UseShellExecute = false;

        process.Start();
        string error = process.StandardError.ReadToEnd();

        process.WaitForExit();

        if (process.ExitCode != 0) {
          Debug.LogError(process.ExitCode + " : " + error);
        }
      }
    }
  }
}

Thanks for sharing the script. I wonder if you are using the same Apache license on this as your other gist.
