PropertyInfo.SetValue Method (Object, Object, BindingFlags, Binder, Object(), CultureInfo)

July 28, 2014

When overridden in a derived class, sets the property value for the given object to the given value, subject to the specified binding constraints, binder, and culture.

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

'Declaration
Public MustOverride Sub SetValue ( _
	obj As Object, _
	value As Object, _
	invokeAttr As BindingFlags, _
	binder As Binder, _
	index As Object(), _
	culture As CultureInfo _
)

Parameters

obj
Type: System.Object
The object whose property value will be set.
value
Type: System.Object
The new value for this property.
invokeAttr
Type: System.Reflection.BindingFlags
The invocation attribute. This must be a bit flag from BindingFlags: InvokeMethod, CreateInstance, Static, GetField, SetField, GetProperty, or SetProperty. A suitable invocation attribute must be specified. If a static member is to be invoked, the Static flag of BindingFlags must be set.
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 Nothing, the default binder is used.
index
Type: System.Object ()
Optional index values for indexed properties. This value should be Nothing for non-indexed properties.
culture
Type: System.Globalization.CultureInfo
The culture for which the resource is to be localized. Note that if the resource is not localized for this culture, the CultureInfo.Parent method will be called successively in search of a match. If this value is Nothing, the CultureInfo is obtained from the CultureInfo.CurrentUICulture property.

ExceptionCondition
ArgumentException

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

-or-

The property's set accessor is not found.

TargetException

The object does not match the target type, or a property is an instance property but obj is Nothing.

TargetParameterCountException

The number of parameters in index does not match the number of parameters the indexed property takes.

MethodAccessException

The property is not accessible to the caller.

TargetInvocationException

An error occurred while setting 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.

In Windows Phone, only accessible properties can be set using reflection.

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