Remarks
Note
This material discusses types and namespaces that are obsolete. For more information, see Deprecated Types in Windows Workflow Foundation 4.5.
This ITypeProvider implementation, in addition to handling compiled assemblies (AddAssembly and AddAssemblyReference methods), can handle types that have not been compiled yet (AddCodeCompileUnit). The limited implementation of System.Type is returned for types referenced using CodeCompileUnit.
Note
TypeProvider only returns public types from referenced assemblies, and both public and non-public types from local assemblies.
Constructors
| TypeProvider(IServiceProvider) |
Initializes a new instance of the TypeProvider class. |
Properties
| AssemblyNameResolver |
Gets or sets the delegate that references a method with one parameter and one return value that returns the assembly display name in which a specified type belongs to. |
| IsSupportedPropertyResolver |
Gets or sets the delegate that references a method with two parameters and one return value that determines whether a specified property is supported in the target .NET Framework. |
| LocalAssembly |
Gets a value that represents the locally defined Assembly for this instance. |
| ReferencedAssemblies |
Gets a collection of all assemblies referenced by the Type. |
| TypeLoadErrors |
Gets an IDictionary of load error exceptions keyed by the Object that causes the Exception. |
Methods
| AddAssembly(Assembly) |
Adds an already-loaded assembly. It is the caller's responsibility to load the assembly, and TypeProvider includes the types from this assembly for dispensing when GetType is called. |
| AddAssemblyReference(String) |
Adds a reference to the Assembly to the internal list. This assembly is used for the Type lookup in the GetType(String) method. |
| AddCodeCompileUnit(CodeCompileUnit) |
Adds a reference to the CodeCompileUnit to the internal list. This CodeCompileUnit is used for the Type lookup in the GetType(String) method. |
| Dispose() |
Releases all resources used by the TypeProvider. |
| Equals(Object) |
Determines whether the specified object is equal to the current object. (Inherited from Object) |
| GetAssemblyName(Type) |
Returns the assembly display name of the assembly in which the specified type is declared. |
| GetEnumNames(Type) |
Provides a string array that contains the names for the specified Enum in indexed order. |
| GetEventHandlerType(EventInfo) |
Gets the Type of an EventHandler, given a reference to an EventInfo. |
| GetHashCode() |
Serves as the default hash function. (Inherited from Object) |
| GetService(Type) | |
| GetType() |
Gets the Type of the current instance. (Inherited from Object) |
| GetType(String, Boolean) |
Gets the type from the set of assemblies added to the |
| GetType(String) |
Gets the type from the set of assemblies added to the |
| GetTypes() |
Creates an array that contains each Type known to this instance. |
| IsAssignable(Type, Type) |
Indicates whether one type can be safely assigned to another type. |
| IsEnum(Type) | |
| IsSubclassOf(Type, Type) |
Indicates whether a Type is a derived class of another Type . |
| IsSupportedProperty(PropertyInfo, Object) |
Returns a value that determines whether the specified property is supported in the target .NET Framework. |
| MemberwiseClone() |
Creates a shallow copy of the current Object. (Inherited from Object) |
| RefreshCodeCompileUnit(CodeCompileUnit, EventHandler) |
Updates the CodeCompileUnit reference associated with this instance. |
| RemoveAssembly(Assembly) |
Removes all references to the subject Assembly from this instance. |
| RemoveAssemblyReference(String) |
Removes a path-based Assembly reference from this instance. |
| RemoveCodeCompileUnit(CodeCompileUnit) |
Removes all references to the subject CodeCompileUnit from this instance. |
| SetLocalAssembly(Assembly) |
Sets the value of the local Assembly to the referenced Assembly . |
| ToString() |
Returns a string that represents the current object. (Inherited from Object) |
Events
| TypeLoadErrorsChanged |
Occurs when the collection TypeLoadErrors is modified. |
| TypesChanged |
Occurs when the collection of defined types is modified. |
