Public Methods

Method	Description
CallMethod ( object instance, string method ) : object	Calls a method on an object dynamically.
CallMethodCom ( object instance, string method ) : object	Wrapper method to call a 'dynamic' (non-typelib) method on a COM object
CallMethodEx ( object parent, string method ) : object	Calls a method on an object with extended . syntax (object: this Method: Entity.CalculateOrderTotal)
CallStaticMethod ( string typeName, string method ) : object	Invokes a static method
CreateComInstance ( string progId ) : object	Creates a COM instance from a ProgID. Loads either Exe or DLL servers.
CreateInstanceFromString ( string typeName ) : object	Creates an instance of a type based on a string. Assumes that the type's
CreateInstanceFromType ( Type typeToCreate ) : object	Creates an instance from a type by calling the parameterless constructor. Note this will not work with COM objects - continue to use the Activator.CreateInstance for COM objects. Class wwUtils
GetField ( object Object, string Property ) : object	Retrieve a field dynamically from an object. This is a simple implementation that's straight Reflection and doesn't support indexers.
GetProperty ( object instance, string property ) : object	Retrieve a property value from an object dynamically. This is a simple version that uses Reflection calls directly. It doesn't support indexers.
GetPropertyCom ( object instance, string property ) : object	Retrieve a dynamic 'non-typelib' property
GetPropertyEx ( object Parent, string Property ) : object	Returns a property or field value using a base object and sub members including . syntax. For example, you can access: this.oCustomer.oData.Company with (this,"oCustomer.oData.Company") This method also supports indexers in the Property value such as: Customer.DataSet.Tables["Customers"].Rows[0]
GetPropertyExCom ( object parent, string property ) : object	Returns a property or field value using a base object and sub members including . syntax. For example, you can access: this.oCustomer.oData.Company with (this,"oCustomer.oData.Company")
GetTypeFromName ( string typeName ) : Type	Helper routine that looks up a type name and tries to retrieve the full type reference in the actively executing assemblies.
SetField ( object Object, string Property, object Value ) : void	Sets the field on an object. This is a simple method that uses straight Reflection and doesn't support indexers.
SetProperty ( object Object, string Property, object Value ) : void	Sets the property on an object. This is a simple method that uses straight Reflection and doesn't support indexers.
SetPropertyCom ( object Object, string Property, object Value ) : void	Sets the property on an object.
SetPropertyEx ( object parent, string property, object value ) : object	Sets a value on an object. Supports . syntax for named properties (ie. Customer.Entity.Company) as well as indexers.
SetPropertyExCom ( object parent, string property, object value ) : object	Sets the value of a field or property via Reflection. This method alws for using '.' syntax to specify objects multiple levels down. ReflectionUtils.SetPropertyEx(this,"Invoice.LineItemsCount",10) which would be equivalent of: this.Invoice.LineItemsCount = 10;
StringToTypedValue ( string sourceString, Type targetType ) : object	Turns a string into a typed value. Useful for auto-conversion routines like form variable or XML parsers.
StringToTypedValue ( string sourceString, Type targetType, CultureInfo culture ) : object	Turns a string into a typed value. Useful for auto-conversion routines like form variable or XML parsers. Class wwUtils
TypedValueToString ( object rawValue ) : string	Converts a type to string if possible. This method uses the current culture for numeric and DateTime values. It calls the ToString() method on common types and uses a type converter on all other objects if available.
TypedValueToString ( object rawValue, CultureInfo culture ) : string	Converts a type to string if possible. This method supports an optional culture generically on any value. It calls the ToString() method on common types and uses a type converter on all other objects if available
