SymbolResolver Class

Definition

Namespace:: System.Activities.Hosting

Assembly:: System.Activities.dll

SymbolResolver is an extension for providing a host LocationReferenceEnvironment containing objects that can be dereferenced by a string name. Values provided through a SymbolResolver are not persisted. Persistence of SymbolResolver values is a host responsibility.

Constructors

SymbolResolver()

Initializes a new instance of the SymbolResolver class.

Properties

Count	Gets the number of symbols contained in the SymbolResolver.
IsReadOnly	Gets a value that indicates whether the dictionary of symbols in the SymbolResolver is read-only.
Item[String]	Gets or sets the value of the item associated with the specified key.
Keys	Gets a collection of all keys in the SymbolResolver.
Values	Gets a collection of all values in the SymbolResolver.

Methods

Add(KeyValuePair<String,Object>)	Adds a symbol using the specified key/value pair.
Add(String, Object)	Adds a symbol using the specified symbol name and value.
Add(String, Object, Type)	Adds a symbol using the specified symbol name, value, and type.
Add(String, Type)	Adds a symbol using the specified symbol name and type.
AsLocationReferenceEnvironment()	Returns a LocationReferenceEnvironment instance that enables access to references of symbol values in SymbolResolver represented as LocationReference objects.
Clear()	Removes all symbols from the SymbolResolver.
Contains(KeyValuePair<String,Object>)	Returns a value that indicates whether the SymbolResolver contains the specified symbol.
ContainsKey(String)	Returns a value that indicates whether the SymbolResolver contains a symbol with the specified key.
CopyTo(KeyValuePair<String,Object>[], Int32)	Copies the symbols in the SymbolResolver to an existing one-dimensional array of key/value pairs, starting at the specified array index.
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetEnumerator()	Returns an enumerator that iterates through a collection of key/value pairs where the keys are the symbol names and values the symbol values.
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
Remove(KeyValuePair<String,Object>)	Removes the specified symbol from the SymbolResolver.
Remove(String)	Removes a symbol from the SymbolResolver using a specified key.
ToString()	Returns a string that represents the current object. (Inherited from Object)
TryGetValue(String, Object)	Gets the value associated with the specified key.

Explicit Interface Implementations

IEnumerable.GetEnumerator()

Returns an enumerator that iterates through a collection of key/value pairs where the keys are the symbol names and values the symbol values.

Extension Methods

CopyToDataTable<T>(IEnumerable<T>)	Returns a DataTable that contains copies of the DataRow objects, given an input IEnumerable<T> object where the generic parameter `T` is DataRow.
CopyToDataTable<T>(IEnumerable<T>, DataTable, LoadOption)	Copies DataRow objects to the specified DataTable, given an input IEnumerable<T> object where the generic parameter `T` is DataRow.
CopyToDataTable<T>(IEnumerable<T>, DataTable, LoadOption, FillErrorEventHandler)	Copies DataRow objects to the specified DataTable, given an input IEnumerable<T> object where the generic parameter `T` is DataRow.
Cast<TResult>(IEnumerable)	Casts the elements of an IEnumerable to the specified type.
OfType<TResult>(IEnumerable)	Filters the elements of an IEnumerable based on a specified type.
AsParallel(IEnumerable)	Enables parallelization of a query.
AsQueryable(IEnumerable)	Converts an IEnumerable to an IQueryable.
Ancestors<T>(IEnumerable<T>)	Returns a collection of elements that contains the ancestors of every node in the source collection.
Ancestors<T>(IEnumerable<T>, XName)	Returns a filtered collection of elements that contains the ancestors of every node in the source collection. Only elements that have a matching XName are included in the collection.
DescendantNodes<T>(IEnumerable<T>)	Returns a collection of the descendant nodes of every document and element in the source collection.
Descendants<T>(IEnumerable<T>)	Returns a collection of elements that contains the descendant elements of every element and document in the source collection.

Elements<T>(IEnumerable<T>)	Returns a collection of the child elements of every element and document in the source collection.
Elements<T>(IEnumerable<T>, XName)	Returns a filtered collection of the child elements of every element and document in the source collection. Only elements that have a matching XName are included in the collection.

Nodes<T>(IEnumerable<T>)	Returns a collection of the child nodes of every document and element in the source collection.
Remove<T>(IEnumerable<T>)	Removes every node in the source collection from its parent node.
