Implements a hashtable with the key strongly typed to be a string rather than an object.

Definition

public class StringDictionary: Object, IEnumerable

Members Table

The following table lists the members exposed by the StringDictionary object. Click a tab on the left to choose the type of member you want to view.

Methods

Method	Description
Add	Adds an entry with the specified key and value into the StringDictionary.
Clear	Removes all entries from the StringDictionary.
ContainsKey	Determines if the StringDictionary contains a specific key.
ContainsValue	Determines if the StringDictionary contains a specific value.
CopyTo	Copies the string dictionary values to a one-dimensional Array instance at the specified index.
Equals	Overloaded. Compares two objects to determine if they are equal. (Inherited from Object)
GetEnumerator	Returns an enumerator that can iterate through the StringDictionary.
GetHashCode	Serves as a hash function for a particular type, suitable for use in hashing algorithms and data structures like a hash table. (Inherited from Object)
GetType	Gets the Type of the current instance. (Inherited from Object)
ReferenceEquals	Determines whether the specified Object instances are the same instance. (Inherited from Object)
Remove	Removes the entry with the specified key from the StringDictionary.
StringDictionary	Initializes a new instance of StringDictionary.
ToString	Returns a String that represents the current Object. (Inherited from Object)
this[]	Gets or sets the value associated with the specified key.

Properties

Property	Description
Count	Gets the number of key-and-value pairs in the StringDictionary.
IsSynchronized	Gets a value indicating whether access to the StringDictionary is synchronized.
Keys	Gets a collection of keys in the StringDictionary.
SyncRoot	Gets an object that can be used to synchronize access to the StringDictionary.
Values	Gets a collection of values in the StringDictionary.
