PropertyInfo.GetValue Method (Object, BindingFlags, Binder, Object[], CultureInfo)

When overridden in a derived class, returns the property value of a specified object that has the specified binding, index, and culture-specific information.

Namespace:  System.Reflection
Assembly:  mscorlib (in mscorlib.dll)

public abstract Object GetValue(
	Object obj,
	BindingFlags invokeAttr,
	Binder binder,
	Object[] index,
	CultureInfo culture
)

Parameters

obj
Type: System.Object

The object whose property value will be returned.

invokeAttr
Type: System.Reflection.BindingFlags

A bitwise combination of the following enumeration members that specify the invocation attribute: InvokeMethod, CreateInstance, Static, GetField, SetField, GetProperty, and SetProperty. You must specify a suitable invocation attribute. For example, to invoke a static member, set the Static flag.

binder
Type: System.Reflection.Binder

An object that enables the binding, coercion of argument types, invocation of members, and retrieval of MemberInfo objects through reflection. If binder is null, the default binder is used.

index
Type: System.Object[]

Optional index values for indexed properties. This value should be null for non-indexed properties.

culture
Type: System.Globalization.CultureInfo

The culture for which the resource is to be localized. If the resource is not localized for this culture, the CultureInfo.Parent property will be called successively in search of a match. If this value is null, the culture-specific information is obtained from the CultureInfo.CurrentUICulture property.

Return Value

Type: System.Object
The property value of the specified object.

Implements

_PropertyInfo.GetValue(Object, BindingFlags, Binder, Object[], CultureInfo)

ExceptionCondition
ArgumentException

The index array does not contain the type of arguments needed.

-or-

The property's get accessor is not found.

TargetException

The object does not match the target type, or a property is an instance property but obj is null.

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.

TargetInvocationException

An error occurred while retrieving the property value. For example, an index value specified for an indexed property is out of range. The InnerException property indicates the reason for the error.

To determine whether a property is indexed, use the GetIndexParameters method. If the resulting array has 0 (zero) elements, the property is not indexed.

Because static properties belong to the type, not individual objects, get static properties by passing null 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.

NoteNote

Starting with the .NET Framework 2.0 Service Pack 1, this method can be used to access non-public members if the caller has been granted ReflectionPermission with the ReflectionPermissionFlag.RestrictedMemberAccess flag and if the grant set of the non-public members is restricted to the caller’s grant set, or a subset thereof. (See Security Considerations for Reflection.)

To use this functionality, your application should target the .NET Framework 3.5 or later.
