FieldInfo::Attributes Property

 

Gets the attributes associated with this field.

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

public:
property FieldAttributes Attributes {
	virtual FieldAttributes get() abstract;
}

Property Value

Type: System.Reflection::FieldAttributes

The FieldAttributes for this field.

All members have a set of attributes, which are defined in relation to the specific type of member. FieldAttributes informs the user whether this field is the private field, a static field, and so on.

To get the Attributes property, first get the class Type. From the Type, get the FieldInfo. From the FieldInfo, get the Attributes.

The following code example builds three fields and displays their field attributes. A FieldAttributes value can contain more than one attribute, such as both Public and Literal, as shown in the third field.

using namespace System;
using namespace System::Reflection;
using namespace System::Security::Permissions;

public ref class Demo
{
private:
    // Make three fields:
    // The first field is private.
    String^ m_field;

    // The second field is public.
public:
    String^ Field;

    // The third field is public and literal. 
    literal String^ FieldC = "String C";

    Demo() { m_field = "String A"; Field = "String B"; }
};

static void DisplayField(Object^ obj, FieldInfo^ f)
{ 
    // Display the field name, value, and attributes.
    //
    Console::WriteLine("{0} = \"{1}\"; attributes: {2}", 
        f->Name, f->GetValue(obj), f->Attributes);
};

void main()
{
    Console::WriteLine ("\nReflection.FieldAttributes");
    Demo^ d = gcnew Demo();

    // Get a Type object for Demo, and a FieldInfo for each of
    // the three fields. Use the FieldInfo to display field
    // name, value for the Demo object in d, and attributes.
    //
    Type^ myType = Demo::typeid;

    FieldInfo^ fiPrivate = myType->GetField("m_field",
        BindingFlags::NonPublic | BindingFlags::Instance);
    DisplayField(d, fiPrivate);

    FieldInfo^ fiPublic = myType->GetField("Field",
        BindingFlags::Public | BindingFlags::Instance);
    DisplayField(d, fiPublic);

    FieldInfo^ fiConstant = myType->GetField("FieldC",
        BindingFlags::Public | BindingFlags::Static);
    DisplayField(d, fiConstant);
}

/* This code example produces the following output:

Reflection.FieldAttributes
m_field = "String A"; attributes: Private
Field = "String B"; attributes: Public
FieldC = "String C"; attributes: Public, Static, Literal, HasDefault
