Methods

AndWith<T, U, V>((T, U), V)

Extend a tuple with an additional element.

public static (T, U, V) AndWith<T, U, V>(this (T, U) value, V other)

Parameters

value (T, U)

other V

Returns

(T, U, V)

Type Parameters

T

U

V

AndWith<T, U, V, W>((T, U, V), W)

Extend a tuple with an additional element.

public static (T, U, V, W) AndWith<T, U, V, W>(this (T, U, V) value, W other)

Parameters

value (T, U, V)

other W

Returns

(T, U, V, W)

Type Parameters

T

U

V

W

AsNotNull<T>(object, string?)

Convert value to T and assert that it's not null. Throws an exception otherwise. Lets you generate a null reference stack trace at the point of assignment rather then when dereferenced.

public static T AsNotNull<T>(this object value, string? fieldName = null)

Parameters

value object

fieldName string

Returns

T

Type Parameters

T

As<T>(object)

Cast the element to the specified type T or return the default T otherwise.

public static T? As<T>(this object value)

Parameters

value object

Returns

T

Type Parameters

T

Expand<T, U, V>((T, U), Func<U, (U, V)>)

Expand a tuple by using the expander function on the last element.

public static (T, U, V) Expand<T, U, V>(this (T, U) value, Func<U, (U, V)> expander)

Parameters

value (T, U)

expander Func<U, (U, V)>

Returns

(T, U, V)

Type Parameters

T

U

V

Expand<T, U, V, W>((T, U, V), Func<V, (V, W)>)

Expand a tuple by using the expander function on the last element.

public static (T, U, V, W) Expand<T, U, V, W>(this (T, U, V) value, Func<V, (V, W)> expander)

Parameters

value (T, U, V)

expander Func<V, (V, W)>

Returns

(T, U, V, W)

Type Parameters

T

U

V

W

NotNull<T>(T?, string?)

Assert that the object is not null, and throw an exception if it is. Lets you generate a null reference stack trace at the point of assignment rather then when dereferenced.

public static T NotNull<T>(this T? value, string? fieldName = null)

Parameters

value T

fieldName string

Returns

T

Type Parameters

T

Exceptions

NullReferenceException

OrDefaultWith<T>(T?, Func<T>)

Returns the value, or the result of the provided function if the value is null.

public static T OrDefaultWith<T>(this T? value, Func<T> defaultFunc)

Parameters

value T

defaultFunc Func<T>

Returns

T

Type Parameters

T

OrDefault<T>(T?, T)

Returns the value, or the provided default is value is null.

public static T OrDefault<T>(this T? value, T defaultValue)

Parameters

value T

defaultValue T

Returns

T

Type Parameters

T

Safe<T>(IList<T>, int)
