Hafner.Compatibility.ExtensionAttribute 3.0.3

Package "Hafner.Tools.Enumerable.GetLinearSample" contains an extension method for an IEnumerable&lt;T&gt; that returns a linear sample of the desired number of elements from the collection (or less if the collection does not contain that many elements). Always the first and the last elements are returned and evenly spaced elements in between. Edge cases: <li /> If a negative number of samples is requested, an ArgumentOutOfRangeException is thrown. <li /> If the source list has less elements than samples requested, all elements are returned. <li /> If the source list is null, an empty List&lt;T&gt; is returned. <li /> If 0 samples are requested, an empty List&lt;T&gt; is returned. <li /> If 1 sample is requested, the first element is returned. <li /> If 2 samples are requested, the first and the last elements are returned. Assuming a collection contains 100 elements, a call to `collection.GetLinearSample(10)` would return a new List&lt;T&gt; containing the elements at index 0, 11, 22, 33, 44, 55, 66, 77, 88 and 99. This package supports <br /><li /> .NET framework versions 2.0, 3.0, 3.5, 4.0, 4.0.3, 4.5, 4.5.1, 4.5.2, 4.6, 4.6.1, 4.6.2, 4.7, 4.7.1, 4.7.2, 4.8, 4.8.1<br /><li /> .NET core versions 1.0, 1.1, 2.0, 2.1, 2.2, 3.0, 3.1, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0<br /><li /> .NET standard versions 1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 2.0, 2.1<br />

Meta-package that includes Hafner.Compatibility.* packages (see https://github.com/HugoRoss/Hafner.Compatibility.Packages) as required. See 'PackageReadMe.md' for an overview with the exact types that are currently supported and for which framework they are imported.

Package "Hafner.Extensions.Object.CheckNull" contains an extension method for a `System.Object` that checks whether it is null (Nothing in Visual Basic) an in case it is, throws an `ArgumentNullException` with a speaking message (using the automatically filled in 2nd argument `parameterName`); otherwise, the object is returned. Behavior and edge cases: - If the object is a `System.ValueType` it cannot be called (compile error). - If the object is not `null`, the same instance is returned. - If the object is `null` and the parameter name is `null`, empty or white-space, an `ArgumentNullException` with a generic message is thrown ("The argument is mandatory and cannot be null!") - If the object is `null` and the parameter name is recognized as an expression, an `ArgumentNullException` with an according message is thrown ("The result of the expression '\{paramName}' is mandatory and cannot be null!") - If the object is `null` and the parameter name is recognized as a parameter name, an `ArgumentNullException` with an according message is thrown ("The argument for parameter '\{paramName}' is mandatory and cannot be null!") Supported Frameworks: - .NET Framework versions 2.0, 3.0, 3.5, 4.0, 4.0.3, 4.5, 4.5.1, 4.5.2, 4.6, 4.6.1, 4.6.2, 4.7, 4.7.1, 4.7.2, 4.8, 4.8.1 - .NET Core versions 1.0, 1.1, 2.0, 2.1, 2.2, 3.0, 3.1, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0 - .NET Standard versions 1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 2.0, 2.1
