C# Class Decision.Utility.PropertyReflector

Helps to get and set property values on objects through reflection. Properties of underlying objects can be accessed directly by separating the levels in the hierarchy by dots. To get/set the name of an Ancestor, for objects that have a Parent property, you could use "Parent.Parent.Parent.Name".

Public Methods

Method	Description
GetType ( Type targetType, string propertyName ) : Type	Gets the Type of the given property of the given targetType. The targetType and propertyName parameters can't be null.
GetValue ( object target, string propertyName ) : object	Gets the value of the given property of the given target. If objects within the property hierarchy are null references, null will be returned. The target and propertyName parameters can't be null.
SetValue ( object target, string propertyName, object value ) : void

Private Methods

Method	Description
CalculateDistance ( Type targetObjectType, Type baseType ) : int	Calculates the hierarchy levels between two classes. If the targetObjectType is the same as the baseType, the returned distance will be 0. If the two types do not belong to the same hierarchy, -1 will be returned.
Construct ( Type type ) : object	Creates a new object of the given type, provided that the type has a default (parameterless) constructor. If it does not have such a constructor, an exception will be thrown.
GetBestMatchingProperty ( string propertyName, Type type ) : PropertyInfo	Gets the best matching property info for the given name on the given type if the same property is defined on multiple levels in the object hierarchy.
GetPropertyInfo ( Type type, string propertyName ) : PropertyInfo	Obtains the PropertyInfo for the given propertyName of the given type from the cache. If it is not already in the cache, the PropertyInfo will be looked up and added to the cache.
GetPropertyInfoCache ( Type type ) : PropertyInfoCache	Returns the PropertyInfoCache for the given type. If there isn't one available already, a new one will be created.
GetPropertyNameString ( string propertyList, int level ) : string	Returns a string containing the properties in the propertyList up to the given level, separated by dots. For the propertyList { "Zero", "One", "Two" } and level 1, the string "Zero.One" will be returned.
GetTypeImpl ( Type targetType, string propertyName ) : Type	Returns the type of the given property on the target instance. The type and propertyName parameters can't be null.
GetValueImpl ( object target, string propertyName ) : object	Returns the value of the given property on the target instance. The target instance and propertyName parameters can't be null.
SetValueImpl ( object target, string propertyName, object value ) : void	Sets the given property of the target instance to the given value. Type mismatches in the parameters of these methods will result in an exception. Also, the target instance and propertyName parameters can't be null.

Method Details

GetType() public method

Gets the Type of the given property of the given targetType. The targetType and propertyName parameters can't be null.

public GetType ( Type targetType, string propertyName ) : Type
targetType	System.Type	the target type which contains the property
propertyName	string	the property to get, can be a property on a nested object (eg. "Child.Name")
return	System.Type

GetValue() public method

Gets the value of the given property of the given target. If objects within the property hierarchy are null references, null will be returned. The target and propertyName parameters can't be null.

public GetValue ( object target, string propertyName ) : object
target	object	the target object to get the value from
propertyName	string	the property to get, can be a property on a nested object (eg. "Child.Name")
return	object

SetValue() public method

public SetValue ( object target, string propertyName, object value ) : void
target	object
propertyName	string
value	object	the new value of the property
return	void
