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

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

Implements

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.

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

Note

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 or later.

• ReflectionPermission  

  for accessing non-public fields when the grant set of the non-public members is restricted to the caller's grant set, or a subset thereof. Associated enumeration: ReflectionPermissionFlag.RestrictedMemberAccess

• ReflectionPermission  

  for accessing non-public fields regardless of their grant set. Associated enumeration: ReflectionPermissionFlag.MemberAccess

• ReflectionPermission  

  when invoked late-bound through mechanisms such as Type.InvokeMember. Associated enumeration: ReflectionPermissionFlag.MemberAccess.

• SecurityPermission  

  for updating init-only fields. Associated enumeration: SecurityPermissionFlag.SerializationFormatter.
