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

When overridden in a derived class, sets the value of the field supported by the given object.

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

public abstract void SetValue(
	Object obj,
	Object value,
	BindingFlags invokeAttr,
	Binder binder,
	CultureInfo culture
)

Parameters

obj
Type: System.Object

The object whose field value will be set.

value
Type: System.Object

The value to assign to the field.

invokeAttr
Type: System.Reflection.BindingFlags

A field of Binder that specifies the type of binding that is desired (for example, Binder.CreateInstance or Binder.ExactBinding).

binder
Type: System.Reflection.Binder

A set of properties that enables the binding, coercion of argument types, and invocation of members through reflection. If binder is null, then Binder.DefaultBinding is used.

culture
Type: System.Globalization.CultureInfo

The software preferences of a particular culture.

Implements

_FieldInfo.SetValue(Object, Object, BindingFlags, Binder, CultureInfo)

ExceptionCondition
FieldAccessException

The caller does not have permission to access this field.

TargetException

The obj parameter is null and the field is an instance field.

ArgumentException

The field does not exist on the object.

-or-

The value parameter cannot be converted and stored in the field.

This method will assign value to the field reflected by this instance on obj. If the field is static, obj will be ignored. For non-static fields, obj should be an instance of a class that inherits or declares the field. The new value is passed as an Object. For example, if the field's type is Boolean, an instance of Object with the appropriate Boolean value is passed. Before setting the value, SetValue checks to see if the user has access permission.

NoteNote:

Fully trusted code has the permissions that are needed to access and invoke private constructors, methods, fields, and properties using reflection.

NoteNote:

Starting with the .NET Framework version 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 version 3.5. For more information, see .NET Framework 3.5 Architecture.
