Remarks

The sink provider data is a tree structure of configuration information stored in the <provider> Element (Template) configuration nodes. All sink providers must have a constructor that accepts a IDictionary of properties and a ICollection of these structures if they want to be used from a configuration file.

Constructors

SinkProviderData(String)

Initializes a new instance of the SinkProviderData class.

Properties

Children	Gets a list of the child SinkProviderData nodes.
Name	Gets the name of the sink provider that the data in the current SinkProviderData object is associated with.
Properties	Gets a dictionary through which properties on the sink provider can be accessed.

Methods

Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
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)
ToString()	Returns a string that represents the current object. (Inherited from Object)
