This library includes utilities and services for tasks, security, JSON, etc.


using Trivial.Tasks;

Hit task

You can create a task controller to manage when a handler should be raised.

  • HitTask.Debounce: You may request to call a specific action several times in a short time but only the last one should be processed and previous ones should be ignored. A sample is real-time search suggestion.
  • HitTask.Throttle: You may want to request to call an action only once in a short time even if you request to call several times. A sample is the submit button in a form.
  • HitTask.Times: You can define an action can be only processed only when request to call in the specific times range and others will be ignored. A sample is double click.
  • HitTask.Multiple: A handler to process for the specific times and the state will be reset after a while.

Following is an example for debounce.

// Create a task.
var task = HitTask.Debounce(() =>
    // Do something...
}, TimeSpan.FromMilliseconds(200));

// Raise somewhere.


You can create a linear retry policy by LinearRetryPolicy or a customized one to process an action with the specific retry policy. And you can use ObservableTask to observe the state of an action processing.


Contains the helper functions and extension functions for network, such as HTTP web client and its content.

using Trivial.Net;

And you can also use JsonHttpClient to serialize the JSON format response with retry policy supports. And HttpUri for HTTP URI fields accessing.


using Trivial.Security;


You can convert a PEM (OpenSSL RSA key) or an XML string to the RSAParameters struct.

var parameters = RSAParametersConvert.Parse(pem);

And you can convert back by using the extension method ToPrivatePEMString or ToPublicPEMString. And the extension method ToXElement to XML.

Symmetric & Hash

You can use a symmetric algorithm to encrypt and decrypt a string by calling SymmetricUtilities.Encrypt and SymmetricUtilities.DecryptText functions.

For hash algorithm, you can call HashUtilities.ToHashString function to get hash from a plain string and call HashUtilities.Verify to verify.

Access token

We also provide a set of tools for OAuth including following models.

  • TokenInfo The access token and other properties.
  • AppAccessingKey The app identifier and secret key.
  • OAuthClient The token container with the ability to resolve the access token and create the JSON HTTP web client to access the resources required authentication.

And you can also implement the OAuthBasedClient base class to create your own business HTTP web client factory with OAuth supports.


You can create a JSON web token to get the string encoded by initializing a new instance of the JsonWebToken class or the JsonWebTokenParser class.

var sign = HashSignatureProvider.CreateHS512("a secret string");
var jwt = new JsonWebToken<JsonWebTokenPayload>(new JsonWebTokenPayload
    Id = Guid.NewGuid().ToString("n"),
    Issuer = "example"
}, sign);

// Get authenticiation header value.
var header = jwt.ToAuthenticationHeaderValue();

// Parse.
var jwtSame = JsonWebToken<Model>.Parse(jwtStr, sign); // jwtSame.ToEncodedString() == header.Parameter

Secure string

You can use the extension methods in the SecureStringExtensions class to convert the secret between SecureString and String/StringBuilder/Byte[].

You can also use the class RSASecretExchange to transfer the secret with RSA encryption.


using Trivial.Text;


Includes writable JSON DOM JsonObject and JsonArray. And includes lots of useful converter like following.

  • JsonJavaScriptTicksConverter, and its nullable value conveters and fallback converters, to convert DateTime or DateTime? from/to JavaScript ticks number in JSON.
  • JsonUnixTimestampConverter, and its nullable value conveters and fallback converters, to convert DateTime or DateTime? from/to Unix timestamp number in JSON.
  • JsonNumberConverter and JsonNumberConverter.NumberStringConverter, to read number string in JSON.
  • JsonStringListConverter and its character separated converters (such as JsonStringListConverter.WhiteSpaceSeparatedConverter), to convert a string list from/to a string in JSON.
  • JsonObjectConverter, to convert JsonObject and JsonArray.


You can read CSV file into a list of the specific models. For example, you have a model class CsvModel with string properties A and B, now you can map to the CSV file.

var csv = new CsvParser("abcd,efg\nhijk,lmn");
foreach (var model in csv.ConvertTo<CsvModel>(new[] { "A", "B" }))
    Console.WriteLine("{0},{1}", model.A, model.B);


using Trivial.Data;


You can save a number of model in memory cache by generic class DataCacheCollection.


using Trivial.Maths;


There a lot of arithmetic functions.

Arithmetic.IsPrime(2147483647); // True
Arithmetic.Gcd(192, 128); // 64


You can get the number symbols as you want. And get the numerals in English.

// twelve thousand three hundred and forty-five point six seven

// 1.2M

And ChineseNumerals for Chinese and JapaneseNumerals for Japanese.

Angle and polar point

  • Angle Angle.
  • PolarPoint The point in polar coordinates.
  • SphericalPoint The point in spherical coordinates.


  • NullableValueSimpleInterval<T> Interval, such as [20, 100).

Rectangular coordinates

  • OneDimensionalPoint The point in 1D (line) coordinates.
  • TwoDimensionalPoint The point in 2D (flat) coordinates.
  • ThreeDimensionalPoint The point in 3D (stereoscophic) coordinates.
  • FourDimensionalPoint The point in 4D (spacetime) coordinates.
