 一：系统工具

一：获取本机IP地址

 public static string GetLocalIP(){//Dns.GetHostName()获取本机名Dns.GetHostAddresses()根据本机名获取ip地址组IPAddress[] ips = Dns.GetHostAddresses(Dns.GetHostName());foreach (IPAddress ip in ips){if (ip.AddressFamily == AddressFamily.InterNetwork){return ip.ToString();  //ipv4}}return null;}

二：获取本机MAC地址

 public static string GetMacAddress(){try{NetworkInterface[] nis = NetworkInterface.GetAllNetworkInterfaces();for (int i = 0; i < nis.Length; i++){if (nis[i].Name == "本地连接"){return nis[i].GetPhysicalAddress().ToString();}}return "null";}catch{return "null";}}

三：获取字符串的MD5
 

 // 计算字符串的MD5值public static string Md5String(string source){MD5CryptoServiceProvider md5 = new MD5CryptoServiceProvider();byte[] data = System.Text.Encoding.UTF8.GetBytes(source);byte[] md5Data = md5.ComputeHash(data, 0, data.Length);md5.Clear();string destString = "";for (int i = 0; i < md5Data.Length; i++){destString += System.Convert.ToString(md5Data[i], 16).PadLeft(2, '0');}destString = destString.PadLeft(32, '0');return destString;}

四：计算文件的MD5
 

 public static string Md5File(string file){try{FileStream fs = new FileStream(file, FileMode.Open);string size = fs.Length / 1024 + "";//Debug.Log("当前文件的大小：  " + file + "===>" + (fs.Length / 1024) + "KB");System.Security.Cryptography.MD5 md5 = new System.Security.Cryptography.MD5CryptoServiceProvider();byte[] retVal = md5.ComputeHash(fs);fs.Close();StringBuilder sb = new StringBuilder();for (int i = 0; i < retVal.Length; i++){sb.Append(retVal[i].ToString("x2"));}return sb + "|" + size;}catch (Exception ex){throw new Exception("md5file() fail, error:" + ex.Message);}}

五：MD5的32位加密
 

 // MD5  32位加密public static string UserMd5(string str){string cl = str;StringBuilder pwd = new StringBuilder();MD5 md5 = MD5.Create();//实例化一个md5对像// 加密后是一个字节类型的数组，这里要注意编码UTF8/Unicode等的选择　byte[] s = md5.ComputeHash(Encoding.UTF8.GetBytes(cl));// 通过使用循环，将字节类型的数组转换为字符串，此字符串是常规字符格式化所得for (int i = 0; i < s.Length; i++){// 将得到的字符串使用十六进制类型格式。格式后的字符是小写的字母，如果使用大写（X）则格式后的字符是大写字符pwd.Append(s[i].ToString("x2"));//pwd = pwd + s[i].ToString("X");}return pwd.ToString();}

六：字节的加密解密

  public static void Encypt(ref byte[] targetData, byte m_key){//加密，与key异或，解密的时候同样如此int dataLength = targetData.Length;for (int i = 0; i < dataLength; ++i){targetData[i] = (byte)(targetData[i] ^ m_key);}}

七：Base64编码解码

// Base64编码public static string Encode(string message){byte[] bytes = Encoding.GetEncoding("utf-8").GetBytes(message);return Convert.ToBase64String(bytes);}// Base64解码public static string Decode(string message){byte[] bytes = Convert.FromBase64String(message);return Encoding.GetEncoding("utf-8").GetString(bytes);}

八：随机生成字符串

 public static string RandomCharacters(){string str = string.Empty;long num2 = DateTime.Now.Ticks + 0;System.Random random = new System.Random(((int)(((ulong)num2) & 0xffffffffL)) | ((int)(num2 >> 1)));for (int i = 0; i < 20; i++){char ch;int num = random.Next();if ((num % 2) == 0){ch = (char)(0x30 + ((ushort)(num % 10)));}else{ch = (char)(0x41 + ((ushort)(num % 0x1a)));}str = str + ch.ToString();}return str;}

二：UI控件常用功能及事件监听

一：UI控件添加事件监听
 

 /// <summary>/// UGUI 控件添加事件监听/// </summary>/// <param name="target">事件监听目标</param>/// <param name="type">事件类型</param>/// <param name="callback">回调函数</param>public static void AddEventListener(this RectTransform target, EventTriggerType type, UnityAction<BaseEventData> callback){EventTrigger trigger = target.GetComponent<EventTrigger>();if (trigger == null){trigger = target.gameObject.AddComponent<EventTrigger>();trigger.triggers = new List<EventTrigger.Entry>();}//定义一个事件EventTrigger.Entry entry = new EventTrigger.Entry();//设置事件类型entry.eventID = type;//设置事件回调函数entry.callback = new EventTrigger.TriggerEvent();entry.callback.AddListener(callback);//添加事件到事件组trigger.triggers.Add(entry);}

二：UGUI按钮添加移除点击监听事件

 // UGUI Button添加点击事件监听public static void AddEventListener(this RectTransform target, UnityAction callback){Button button = target.GetComponent<Button>();if (button){button.onClick.AddListener(callback);}else{Debug.Log(target.name + " 丢失了组件 Button！");}}// UGUI Button移除所有事件监听public static void RemoveAllEventListener(this RectTransform target){Button button = target.GetComponent<Button>();if (button){button.onClick.RemoveAllListeners();}else{Debug.Log(target.name + " 丢失了组件 Button！");}}

三：判定鼠标是否停留在ui控件上
 

   public static bool IsPointerOverUGUI(){if (EventSystem.current){return EventSystem.current.IsPointerOverGameObject();}else{return false;}}

四：限制Text内容的长度

   // 限制Text内容的长度在length以内，超过的部分用replace代替public static void RestrictLength(this Text tex, int length, string replace){if (tex.text.Length > length){tex.text = tex.text.Substring(0, length) + replace;}}

五：富文本限制Text内指定内容的大小颜色加粗斜体

三:坐标系转换

  public enum UIType{/// <summary>/// 屏幕UI/// </summary>Overlay,/// <summary>/// 摄像机UI/// </summary>Camera,/// <summary>/// 世界UI/// </summary>World}

二：读文件

    //读出来public static string ReadFile(string pathName){StreamReader sr;FileInfo fi = new FileInfo(pathName);sr = fi.OpenText();string info = sr.ReadToEnd();sr.Close();sr.Dispose();return info;}

六：数学工具

一：几率问题设置

 /**加*///rate:几率数组（%），  total：几率总和（100%）// Debug.Log(rand(new int[] { 10, 5, 15, 20, 30, 5, 5,10 }, 100));public static int rand(int[] rate, int total){int r = UnityEngine.Random.Range(1, total + 1);int t = 0;for (int i = 0; i < rate.Length; i++){t += rate[i];if (r < t){return i;}}return 0;}/**减*///rate:几率数组（%），  total：几率总和（100%）// Debug.Log(randRate(new int[] { 10, 5, 15, 20, 30, 5, 5,10 }, 100));public static int randRate(int[] rate, int total){int rand = UnityEngine.Random.Range(0, total + 1);for (int i = 0; i < rate.Length; i++){rand -= rate[i];if (rand <= 0){return i;}}return 0;}
