Returns a string representation of the integer argument as an unsigned integer in base 16. The unsigned integer value is the argument plus 2^32 if the argument is negative; otherwise, it is equal to the argument. This value is converted to a string of ASCII digits in hexadecimal (base 16)...
Java.Lang 組件: Mono.Android.dll 以base 16中的不帶正負號整數形式傳回整數自變數的字串表示。 [Android.Runtime.Register("toHexString", "(I)Ljava/lang/String;", "")] public static string ToHexString(int i); 參數 i Int32 要轉換成字串的整數。
public static String bytes2HexString(byte[] b) { String ret = ""; for (int i = 0; i < b.length; i++) { String hex = Integer.toHexString(b[ i ] & 0xFF); if (hex.length() == 1) { hex = '0' + hex; } ret += hex.toUpperCase(); } return ret; } 1. 2. 3. 4....
8进制(oct)—前缀加0,16进制(hex)—前缀加0x或者0X。string前后加上双引号,告诉编译器把它当成一串字符来解释。 2 int转化为string或者char* 2.1 to_string函数 c++11标准增加了全局函数std::to_string: string to_string (int val); string to_string (long val); string to_string (long long val); s...
