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);
}

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();

//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);

}
}
// UGUI Button移除所有事件监听
public static void RemoveAllEventListener(this RectTransform target)
{
Button button = target.GetComponent();
if (button)
{
button.onClick.RemoveAllListeners();

else return;
tex.text = valueRich;
}
// 限制Text中的指定子字串的字体加粗
public static void ToRichBold(this Text tex, string subStr)
{
if (subStr.Length <= 0 || !tex.text.Contains(subStr))
{
return;
}
string valueRich = tex.text;
int index = valueRich.IndexOf(subStr);
if (index >= 0) valueRich = valueRich.Insert(index, "");
else return;
index = valueRich.IndexOf(subStr) + subStr.Length;
if (index >= 0) valueRich = valueRich.Insert(index, " ");
else return;
tex.text = valueRich;
}
// 限制Text中的指定子字串的字体斜体
public static void ToRichItalic(this Text tex, string subStr)
{
if (subStr.Length <= 0 || !tex.text.Contains(subStr))
{
return;
}
string valueRich = tex.text;
int index = valueRich.IndexOf(subStr);
if (index >= 0) valueRich = valueRich.Insert(index, "");
else return;
index = valueRich.IndexOf(subStr) + subStr.Length;
if (index >= 0) valueRich = valueRich.Insert(index, " ");
else return;
tex.text = valueRich;
}
// 清除所有富文本样式
public static void ClearRich(this Text tex)
{
string value = tex.text;
for (int i = 0; i < value.Length; i++)
{
if (value[i] == '<')
{
for (int j = i + 1; j < value.Length; j++)
{
if (value[j] == '>')
{
int count = j - i + 1;
value = value.Remove(i, count);
i -= 1;
break;
}
}
}
}
tex.text = value;

{
Transform searchTrans = goParent.transform.Find(childName);
if (searchTrans == null)
{
foreach (Transform trans in goParent.transform)

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*/
