Represents a nongeneric collection of key/value pairs.
Assembly: mscorlib (in mscorlib.dll)
Thetype exposes the following members.
|Count||Gets the number of elements contained in the ICollection. (Inherited from ICollection.)|
|IsFixedSize||Gets a value indicating whether the object has a fixed size.|
|IsReadOnly||Gets a value indicating whether the object is read-only.|
|IsSynchronized||Gets a value indicating whether access to the ICollection is synchronized (thread safe). (Inherited from ICollection.)|
|Item||Gets or sets the element with the specified key.|
|Keys||Gets an ICollection object containing the keys of the object.|
|SyncRoot||Gets an object that can be used to synchronize access to the ICollection. (Inherited from ICollection.)|
|Values||Gets an ICollection object containing the values in the object.|
|Add||Adds an element with the provided key and value to the object.|
|Clear||Removes all elements from the object.|
|Contains||Determines whether the object contains an element with the specified key.|
|CopyTo||Copies the elements of the ICollection to an Array, starting at a particular Array index. (Inherited from ICollection.)|
|GetEnumerator||Returns an enumerator that iterates through a collection. (Inherited from IEnumerable.)|
|Remove||Removes the element with the specified key from the object.|
The interface is the base interface for nongeneric collections of key/value pairs.
Each element is a key/value pair stored in a DictionaryEntry object.
Each pair must have a unique key. Implementations can vary in whether they allow the key to be null. The value can be null and does not have to be unique. The interface allows the contained keys and values to be enumerated, but it does not imply any particular sort order.
implementations fall into three categories: read-only, fixed-size, variable-size. A read-only object cannot be modified. A fixed-size object does not allow the addition or removal of elements, but does allow the modification of existing elements. A variable-size object allows the addition, removal, and modification of elements.
