Parameters

System.Windows.DependencyObject dependencyObject The dependency object.

System.Windows.DependencyProperty dependencyProperty The dependency property to clear.

Returns

System.Boolean Returns true if the value has been cleared.

Exceptions

System.ArgumentNullException Will be raised if either the dependencyObject or the dependencyProperty is null.

Clone(IEnumerable<Double>)

Clones the list of doubles and returns a System.Windows.Media.DoubleCollection.

Declaration

public static DoubleCollection Clone(this IEnumerable<double> doubles)

Parameters

System.Collections.Generic.IEnumerable<System.Double> doubles The list to clone.

Returns

System.Windows.Media.DoubleCollection The cloned list.

Clone<T>(IEnumerable<T>)

Clones the list.

Declaration

public static IList<T> Clone<T>(this IEnumerable<T> list)

Parameters

System.Collections.Generic.IEnumerable<T> list The list to clone.

Returns

System.Collections.Generic.IList<T> The cloned list.

Type Parameters

T The data type of the list.

Exceptions

System.ArgumentNullException Will be raised if the underlying list is null.

ContainsAny<T>(IEnumerable<T>, IEnumerable<T>)

Checks for the occurrence of the given items in the collection.

Declaration

public static bool ContainsAny<T>(this IEnumerable<T> collection, IEnumerable<T> otherCollection)

Parameters

System.Collections.Generic.IEnumerable<T> collection A collection to be tested for the given items.

System.Collections.Generic.IEnumerable<T> otherCollection The other collection.

Returns

System.Boolean True if the specified collection contains any of the otherCollection items; otherwise, false.

Type Parameters

T

Exceptions

System.ArgumentNullException Will be raised if either the collection or the otherCollection is null.

EnsureListCount<T>(IList<T>, Int32, Func<T>)

Ensures the list has exactly the amount of items specified.

Declaration

Parameters

System.Collections.Generic.IList<T> list The list to check.

System.Int32 count The expected count.

System.Func<T> factory The factory function if more items need to be created.

Returns

System.Boolean Returns true if items had to be removed in order to have the expect count.

Type Parameters

T The data type of the list.

Exceptions

System.ArgumentNullException Will be raised if the underlying list is null.

EnsureListCountAtLeast<T>(IList<T>, Int32, Func<T>)

Ensures that the list contains at least the amount of specified items. If not, the given factory function will be used to add additional items till the expect count is reached.

Declaration
