Sion.Useful

NuGet package that provides static and extension methods to DateTime and string.

Sion.Useful.DateTimeMethods

public static long ConvertToUnixMilliseconds(DateTime date)
public static long ConvertToUnixSeconds(DateTime date)
public static long GetUnixMillisecondsNow()
public static long GetUnixSecondsNow()
public static long ToUnixMilliseconds(this DateTime date)
public static long ToUnixSeconds(this DateTime date)

Sion.Useful.StringMethods

public static string Base64ToUtf8(this string base64)
public static string Utf8ToBase64(this string utf8)

How to use

First, download the Sion.Useful NuGet package, then include this using statement at the top of the file:

using Sion.Useful;

DateTimeMethods

Getting Unix seconds and milliseconds

// Using extension methods
DateTime date = Convert.ToDateTime("2000-01-01T12:00:00.000");
long unixMilliseconds = date.ToUnixMilliseconds();
long unixSeconds = date.ToUnixSeconds();

long unixMillisecondsNow = DateTime.Now.ToUnixMilliseconds();
long unixSeconds = DateTime.Now.ToUnixSeconds();

// Using static methods
DateTime date = Convert.ToDateTime("2000-01-01T12:00:00.000");
long unixMilliseconds = DateTimeMethods.ConvertToUnixMilliseconds(date);
long unixSeconds = DateTimeMethods.ConvertToUnixSeconds(date);

long unixMillisecondsNow = DateTimeMethods.GetUnixMillisecondsNow();
long unixSecondsNow = DateTimeMethods.GetUnixSecondsNow();

StringMethods

Converting between UTF-8 and Base64 strings

// Using extension methods
string utf8 = "hello";
string base64 = utf8.Utf8ToBase64(); // aGVsbG8=

base64 = "Ym9uam91cg==";
utf8 = base64.Base64ToUtf8(); // bonjour

// Using static methods
string utf8 = "hello";
string base64 = StringMethods.Utf8ToBase64(utf8); // aGVsbG8=

base64 = "Ym9uam91cg==";
utf8 = StringMethods.Base64ToUtf8(base64); // bonjour
