FirstOrDefaultWhere< T1, T2 >()

static T2 Infohazard.Core.EnumerableUtility.FirstOrDefaultWhere< T1, T2 > ( this IEnumerable< T1 >  input, SelectWhereDelegate< T1, T2 >  selectionDelegate  )

static

Perform select/map and where/filter operations on a sequence with a single function, and returns the result of the select operation for the first passing element.

Parameters

input	The input sequence.
selectionDelegate	The delegate to use.

Template Parameters

T1	Input type of the delegate.
T2	Output type of the select operation.

Returns

The result of the select operation for the first passing element.

IndexOf< T >()

static int Infohazard.Core.EnumerableUtility.IndexOf< T > ( this IReadOnlyList< T >  list, in T  item  )

static

IndexOf operation for an IReadOnlyList, which is not included in .NET.

This cannot take into account custom equality comparers.

Parameters

list	List to search.
item	Item to search for.

Template Parameters

T	Type of items in the list.

Returns

The index of the item, or -1 if not found.

SelectWhere< T1, T2 >()

static IEnumerable< T2 > Infohazard.Core.EnumerableUtility.SelectWhere< T1, T2 > ( this IEnumerable< T1 >  input, SelectWhereDelegate< T1, T2 >  selectionDelegate  )

static

Perform select/map and where/filter operations on a sequence with a single function.

Parameters

input	The input sequence.
selectionDelegate	The delegate to use.

Template Parameters

T1	Input type of the delegate.
T2	Output type of the select operation.

Returns

The resulting sequence.

SelectWhereDelegate< in T1, T2 >()

delegate bool Infohazard.Core.EnumerableUtility.SelectWhereDelegate< in T1, T2 >	(	T1	input,
		out T2	output
	)

Delegate for functions that perform both a select/map and where/filter operation.

Template Parameters

T1	Input type of the function.
T2	Output type of the select operation.
