  NameDescription
Public methodXmlPreloadedResolver()Initializes a new instance of the XmlPreloadedResolver class.
Public methodXmlPreloadedResolver(XmlKnownDtds)Initializes a new instance of the XmlPreloadedResolver class with the specified preloaded well-known DTDs.
Public methodXmlPreloadedResolver(XmlResolver)Initializes a new instance of the XmlPreloadedResolver class with the specified fallback resolver.
Public methodXmlPreloadedResolver(XmlResolver, XmlKnownDtds)Initializes a new instance of the XmlPreloadedResolver class with the specified fallback resolver and preloaded well-known DTDs.

  NameDescription
Public propertyCredentialsSets credentials that are used to authenticate underlying WebRequest. (Overrides XmlResolver.Credentials.)
Public propertyPreloadedUrisGets a collection of preloaded URIs.

  NameDescription
Public methodAdd(Uri, Byte[])Adds a Stream, byte array, or string with preloaded data to the XmlPreloadedResolver store and maps it to a URI. If the store already contains a mapping for the same URI, the existing mapping is overridden.
Public methodAdd(Uri, Stream)Adds a Stream, byte array, or string with preloaded data to the XmlPreloadedResolver store and maps it to a URI. If the store already contains a mapping for the same URI, the existing mapping is overridden.
Public methodAdd(Uri, String)Adds a Stream, byte array, or string with preloaded data to the XmlPreloadedResolver store and maps it to a URI. If the store already contains a mapping for the same URI, the existing mapping is overridden.
Public methodAdd(Uri, Byte[], Int32, Int32)Adds a Stream, byte array, or string with preloaded data to the XmlPreloadedResolver store and maps it to a URI. If the store already contains a mapping for the same URI, the existing mapping is overridden.
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetEntityMaps a URI to an object that contains the actual resource. (Overrides XmlResolver.GetEntity(Uri, String, Type).)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodRemoveRemoves the data that corresponds to the URI from the XmlPreloadedResolver.
Public methodResolveUriReturns true if the resolver’s GetEntity method can resolve the provided URI into an instance of the provided Type. (Overrides XmlResolver.ResolveUri(Uri, String).)
Public methodSupportsTypeReturns true if the resolver’s GetEntity method can resolve the provided URI into an instance of the provided Type. (Overrides XmlResolver.SupportsType(Uri, Type).)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

The XmlPreloadedResolver type is used as a resolver when automatic calls to the network are not desired or are not possible. For example, this type can be used for loading cached external DTDs. Or, you might use XmlPreloadedResolver to preload well-known DTDs that are defined in XHTML 1.0. Preloading well-known DTDs does not start any network connections because these DTDs are already embedded in the System.Xml.Utils assembly. Currently, XmlPreloadedResolver includes the DTDs that are defined in XHTML 1.0 and RSS 0.91.
