System.Collections.Generic.Dictionary<TKey,TValue>.ValueCollection Class

public sealed class Dictionary<TKey,TValue>.ValueCollection: ICollection<TKey>, IEnumerable<TKey>, ICollection, IEnumerable

Base Types

Object
  Dictionary<TKey,TValue>.ValueCollection

This type implements ICollection, IEnumerable, System.Collections.Generic.ICollection<TKey>, and System.Collections.Generic.IEnumerable<TKey>.

Assembly

mscorlib

Library

BCL

Summary

Represents a read-only collection of values in a dictionary.

Description

The System.Collections.Generic.Dictionary<TKey,TValue>.Values property returns an instance of this type, containing all the values in that dictionary. The order of the values in the value collection is unspecified, but it is the same order as the associated values in the key collection returned by the System.Collections.Generic.Dictionary<TKey,TValue>.Keys property.

If the underlying dictionary is modified, or the value of any key in that dictionary is modified, the behavior of the value collection is unspecified.

Dictionary<TKey,TValue>.ValueCollection Constructor

public ValueCollection(Dictionary<TKey,TValue> dictionary)

Summary

Initializes a new value collection to reflect the values from the specified dictionary.

Parameters

dictionary
The dictionary whose values are to be reflected in the value collection.

Exceptions

Exception TypeCondition
ArgumentNullExceptiondictionary is null .

Dictionary<TKey,TValue>.ValueCollection.CopyTo Method

public void CopyTo(TValue[] array, int arrayIndex)

Summary

Copies the elements of the value collection to a Array, starting at a particular index.

Parameters

array
A one-dimensional, zero-based Array that is the destination of the elements copied from the value collection.
arrayIndex
The zero-based index in array at which copying begins.

Exceptions

Exception TypeCondition
ArgumentExceptionarray is multidimensional.

-or-

array does not have zero-based indexing.

-or-

arrayIndex is greater than the length of array.

-or-

The number of elements in the value collection is greater than the available space from arrayIndex to the end of the destination array.

-or-

Some element of the value collection is not assignable to the element type of the array.

ArgumentNullExceptionarray is null .

ArgumentOutOfRangeExceptionarrayIndex < 0.

Description

The elements are copied into the array in the same order in which the enumerator iterates through the value collection.

Dictionary<TKey,TValue>.ValueCollection.GetEnumerator Method

public Dictionary<TKey,TValue>.ValueCollection.Enumerator GetEnumerator()

Summary

Returns an enumerator that can be used to iterate over the value collection.

Return Value

An enumerator for the value collection.

Description

If the underlying dictionary is modified, or the value of any key in that dictionary is modified, the behavior of the enumerator is unspecified.
