PropertyInfo.GetValue Method (Object, Object[])

.NET Framework 1.1

Returns the value of the property with optional index values for indexed properties.

[Visual Basic]
Overloads Public Overridable Function GetValue( _
   ByVal obj As Object, _
   ByVal index() As Object _
) As Object
[C#]
public virtual object GetValue(
 object obj,
 object[] index
);
[C++]
public: virtual Object* GetValue(
 Object* obj,
 Object* index __gc[]
);
[JScript]
public function GetValue(
   obj : Object,
 index : Object[]
) : Object;

Parameters

obj
The object whose property value will be returned.
index
Optional index values for indexed properties. This value should be a null reference (Nothing in Visual Basic) for non-indexed properties.

Return Value

The property value for the obj parameter.

Exceptions

Exception Type Condition
ArgumentException The index array does not contain the type of arguments needed.

-or-

The property's Get method is not found.

TargetException The object does not match the target type, or a property is an instance property but obj is a null reference (Nothing in Visual Basic).
TargetParameterCountException The number of parameters in index does not match the number of parameters the indexed property takes.
MethodAccessException There was an illegal attempt to access a private or protected method inside a class.

Remarks

This is a convenience method that provides an implementation for the abstract GetValue method with a BindingFlags parameter of DefaultChangeType, the Binder set to a null reference (Nothing in Visual Basic), and the CultureInfo set to a null reference (Nothing).

Because static properties belong to the type, not individual objects, get static properties by passing a null reference (Nothing) as the object argument. For example, use the following code to get the static CurrentCulture property of CultureInfo:

PropertyInfo CurCultProp = (typeof(CultureInfo)).GetProperty("CurrentCulture");

Console.WriteLine("CurrCult: " + CurCultProp.GetValue(null,null));

To use the GetValue method, first get the class Type. From the Type, get the PropertyInfo. From the PropertyInfo, use the GetValue method.
