This is handy for [custom constructions](https://github.com/samuel-lucas6/kcChaCha20-Poly1305). ## Usage ### EqualTo Checks that an integer is equal to a required value. ```csharp Validation.EqualTo(string paramName, T value, T required) where T : IBinaryInteger ``` #### Exceptions [ArgumentOutOfRangeException](https://docs.microsoft.com/en-us/dotnet/api/system.argumentoutofrangeexception) `value` must be equal to `required`. ### Between Checks that an integer is between a minimum and maximum value (exclusive). ```csharp Validation.Between(string paramName, T value, T min, T max) where T : IBinaryInteger ``` #### Exceptions [ArgumentOutOfRangeException](https://docs.microsoft.com/en-us/dotnet/api/system.argumentoutofrangeexception) `value` must be between `min` and `max` (exclusive). ### BetweenOrEqualTo Checks that an integer is between a minimum and maximum value (inclusive). ```csharp Validation.BetweenOrEqualTo(string paramName, T value, T min, T max) where T : IBinaryInteger) ``` #### Exceptions [ArgumentOutOfRangeException](https://docs.microsoft.com/en-us/dotnet/api/system.argumentoutofrangeexception) `value` must be between `min` and `max` (inclusive). ### GreaterThan Checks that an integer is greater than a minimum value. ```csharp Validation.GreaterThan(string paramName, T value, T min) where T : IBinaryInteger ``` #### Exceptions [ArgumentOutOfRangeException](https://docs.microsoft.com/en-us/dotnet/api/system.argumentoutofrangeexception) `value` must be greater than `min`. ### GreaterThanOrEqualTo Checks that an integer is greater than or equal to a minimum value. ```csharp Validation.GreaterThanOrEqualTo(string paramName, T value, T min) where T : IBinaryInteger ``` #### Exceptions [ArgumentOutOfRangeException](https://docs.microsoft.com/en-us/dotnet/api/system.argumentoutofrangeexception) `value` must be greater than or equal to `min`. ### LessThan Checks that an integer is less than a maximum value. ```csharp Validation.LessThan(string paramName, T value, T max) where T : IBinaryInteger ``` #### Exceptions [ArgumentOutOfRangeException](https://docs.microsoft.com/en-us/dotnet/api/system.argumentoutofrangeexception) `value` must be less than `max`. ### LessThanOrEqualTo Checks that an integer is less than or equal to a maximum value. ```csharp Validation.LessThanOrEqualTo(string paramName, T value, T max) where T : IBinaryInteger ``` #### Exceptions [ArgumentOutOfRangeException](https://docs.microsoft.com/en-us/dotnet/api/system.argumentoutofrangeexception) `value` must be less than or equal to `max`. ### MultipleOf Checks that an integer is a multiple of another integer. ```csharp Validation.MultipleOf(string paramName, T value, T multipleOf) where T : IBinaryInteger ``` #### Exceptions [ArgumentOutOfRangeException](https://docs.microsoft.com/en-us/dotnet/api/system.argumentoutofrangeexception) `value` must be a multiple of `multipleOf` (and not less than or equal to 0). ### NotEmpty Checks that an integer (e.g., the length of a span) is not equal to zero. ```csharp Validation.NotEmpty(string paramName, T size) where T : IBinaryInteger ``` #### Exceptions [ArgumentOutOfRangeException](https://docs.microsoft.com/en-us/dotnet/api/system.argumentoutofrangeexception) `size` must not be equal to 0. ### NotNull Checks that a parameter is not null. ```csharp Validation.NotNull(string paramName, T? value) ``` #### Exceptions [ArgumentNullException](https://docs.microsoft.com/en-us/dotnet/api/system.argumentnullexception) `value` must not be null. ### NotNullOrEmpty Checks that an enumerable (e.g., array) is not null or empty. ```csharp Validation.NotNullOrEmpty(string paramName, IEnumerable enumerable) ``` #### Exceptions [ArgumentNullException](https://docs.microsoft.com/en-us/dotnet/api/system.argumentnullexception) `enumerable` must not be null. [ArgumentOutOfRangeException](https://docs.microsoft.com/en-us/dotnet/api/system.argumentoutofrangeexception) `enumerable` must not be empty. ### HasNoNullValues Checks that an enumerable (e.g., array) is not null and has no null values. ```csharp Validation.HasNoNullValues(string paramName, IEnumerable enumerable) ``` #### Exceptions [ArgumentNullException](https://docs.microsoft.com/en-us/dotnet/api/system.argumentnullexception) `enumerable` must not be null. [ArgumentException](https://learn.microsoft.com/en-us/dotnet/api/system.argumentexception) `enumerable` must not contain any null values. ### HasNoNullOrEmptyValues Checks that an enumerable (e.g., string array) is not null/empty and has no null/empty values. ```csharp Validation.HasNoNullOrEmptyValues(string paramName, IEnumerable enumerable) ``` #### Exceptions [ArgumentNullException](https://docs.microsoft.com/en-us/dotnet/api/system.argumentnullexception) `enumerable` must not be null. [ArgumentOutOfRangeException](https://docs.microsoft.com/en-us/dotnet/api/system.argumentoutofrangeexception) `enumerable` must not be empty. [ArgumentException](https://learn.microsoft.com/en-us/dotnet/api/system.argumentexception) `enumerable` must not contain any null or empty values. ### HasNoNullValues Checks that a jagged enumerable (e.g., jagged array) is not null and has no null values. ```csharp Validation.HasNoNullValues(string paramName, IEnumerable jaggedEnumerable) ``` #### Exceptions [ArgumentNullException](https://docs.microsoft.com/en-us/dotnet/api/system.argumentnullexception) `jaggedEnumerable` must not be null. [ArgumentException](https://learn.microsoft.com/en-us/dotnet/api/system.argumentexception) `jaggedEnumerable` must not contain any null collections/values. ### HasNoNullOrEmptyValues Checks that a jagged enumerable (e.g., jagged string array) is not null/empty and has no null/empty values. ```csharp Validation.HasNoNullOrEmptyValues(string paramName, IEnumerable jaggedEnumerable) ``` #### Exceptions [ArgumentNullException](https://docs.microsoft.com/en-us/dotnet/api/system.argumentnullexception) `jaggedEnumerable` must not be null. [ArgumentOutOfRangeException](https://docs.microsoft.com/en-us/dotnet/api/system.argumentoutofrangeexception) `jaggedEnumerable` must not be empty. [ArgumentException](https://learn.microsoft.com/en-us/dotnet/api/system.argumentexception) `jaggedEnumerable` must not contain any null or empty collections/values. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://www.geralt.xyz/advanced/validation.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
