Methods

Add(KeyValuePair<String, Object>)

Adds an item to the MetadataDictionary.

public void Add(KeyValuePair<string, object> item)

Parameters

item KeyValuePair<String, Object>

The object to add to the MetadataDictionary.

Add(String, Object)

Adds an element with the provided key and value to the MetadataDictionary.

public void Add(string key, object value)

Parameters

key String

The object to use as the key of the element to add.

value Object

The object to use as the value of the element to add.

Clear()

Removes all items from the MetadataDictionary.

public void Clear()

Contains(KeyValuePair<String, Object>)

Determines whether the MetadataDictionary contains a specific value.

public bool Contains(KeyValuePair<string, object> item)

Parameters

item KeyValuePair<String, Object>

The object to locate in the MetadataDictionary.

Returns

Boolean

true if item is found in the MetadataDictionary; otherwise, false.

ContainsKey(String)

Determines whether the MetadataDictionary contains an element with the specified key.

public bool ContainsKey(string key)

Parameters

key String

The key to locate in the MetadataDictionary.

Returns

Boolean

true if the MetadataDictionary contains an element with the key; otherwise, false.

CopyTo(KeyValuePair<String, Object>[], Int32)

Copies the elements of the MetadataDictionary to an array of type System.Collections.Generic.KeyValuePair<TKey, TValue>, starting at the specified array index.

public void CopyTo(KeyValuePair<string, object>[] array, int arrayIndex)

Parameters

array KeyValuePair<String, Object>[]

The one-dimensional System.Array that is the destination of the elements copied from MetadataDictionary. The System.Array must have zero-based indexing.

arrayIndex Int32

The zero-based index in array at which copying begins.

GetEnumerator()

Returns an enumerator that iterates through the collection.

public IEnumerator<KeyValuePair<string, object>> GetEnumerator()

Returns

IEnumerator<KeyValuePair<String, Object>>

An enumerator that can be used to iterate through the collection.

Remove(KeyValuePair<String, Object>)

Removes the first occurrence of a specific object from the MetadataDictionary.

public bool Remove(KeyValuePair<string, object> item)

Parameters

item KeyValuePair<String, Object>

The object to remove from the MetadataDictionary.

Returns

Boolean

true if item was successfully removed from the MetadataDictionary; otherwise, false. This method also returns false if item is not found in the original MetadataDictionary.

Remove(String)

Removes the element with the specified key from the MetadataDictionary.

public bool Remove(string key)

Parameters

key String

The key of the element to remove.

Returns

Boolean

true if the element is successfully removed; otherwise, false. This method also returns false if key was not found in the original MetadataDictionary.

Gets the value associated with the specified key.

public bool TryGetValue(string key, out object value)

Parameters

key String

The key whose value to get.

value Object

When this method returns, the value associated with the specified key, if the key is found; otherwise, the default value for the type of the value parameter. This parameter is passed uninitialized.

Returns

Boolean

true if the object that implements MetadataDictionary contains an element with the specified key; otherwise, false.
