最近經常需要些一個編譯工作腳本,經常操作一個文件。下面是一個彙總了的文件操作方法。
using UnityEngine;
#if UNITY_EDITOR
using UnityEditor;
using System;
using System.IO;
using System.Threading;
public static class FileStaticAPI

public static bool IsFileExists (string fileName)
{
if (fileName.Equals (string.Empty)) {
return false;
}

}
/// 在Application.dataPath目錄下創建文件
public static void CreateFile (string fileName)
{
if (!IsFileExists (fileName)) {
CreateFolder (fileName.Substring (0, fileName.LastIndexOf ('/')));
#if UNITY_4 || UNITY_5
FileStream stream = File.Create (GetFullPath (fileName));
stream.Close ();
#else
File.Create (GetFullPath (fileName));
#endif
}
}
/// 寫入數據到對應文件
public static void Write (string fileName, string contents)

AssetDatabase.Refresh ();

需要的可以拿去用用。
