	Count	Gets the number of key/value pairs contained in the SortedList<TKey, TValue>. (Inherited from SortedList<Int32, IServiceProvider>.)
	Item	Gets or sets the value associated with the specified key. (Inherited from SortedList<Int32, IServiceProvider>.)
	Keys	Gets a collection containing the keys in the SortedList<TKey, TValue>. (Inherited from SortedList<Int32, IServiceProvider>.)
	Values	Gets a collection containing the values in the SortedList<TKey, TValue>. (Inherited from SortedList<Int32, IServiceProvider>.)

Methods

	Name	Description
	Add	Adds an element with the specified key and value into the SortedList<TKey, TValue>. (Inherited from SortedList<Int32, IServiceProvider>.)
	Clear	Removes all elements from the SortedList<TKey, TValue>. (Inherited from SortedList<Int32, IServiceProvider>.)
	ContainsKey	Determines whether the SortedList<TKey, TValue> contains a specific key. (Inherited from SortedList<Int32, IServiceProvider>.)
	ContainsValue	Determines whether the SortedList<TKey, TValue> contains a specific value. (Inherited from SortedList<Int32, IServiceProvider>.)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	GetEnumerator	Returns an enumerator that iterates through the SortedList<TKey, TValue>. (Inherited from SortedList<Int32, IServiceProvider>.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetService	Gets a service of the specified type.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IndexOfKey	Searches for the specified key and returns the zero-based index within the entire SortedList<TKey, TValue>. (Inherited from SortedList<Int32, IServiceProvider>.)
	IndexOfValue	Searches for the specified value and returns the zero-based index of the first occurrence within the entire SortedList<TKey, TValue>. (Inherited from SortedList<Int32, IServiceProvider>.)

	ToString	Returns a string that represents the current object. (Inherited from Object.)
	TrimExcess	Sets the capacity to the actual number of elements in the SortedList<TKey, TValue>, if that number is less than 90 percent of current capacity. (Inherited from SortedList<Int32, IServiceProvider>.)
	TryGetValue	Gets the value associated with the specified key. (Inherited from SortedList<Int32, IServiceProvider>.)

Remarks

It stores IServiceProvider objects in a sorted dictionary for an ordered retrieval. When GetService is called to retrieve a service, the service providers are queried in a specific order. This is useful when multiple service providers are combined such as in the WindowPane implementation.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
