Attributes Property

FieldInfo.Attributes Property

Gets the attributes associated with this field.

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

public abstract FieldAttributes Attributes { get; }

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 System;
using System.Reflection;

public class Demo
    // Make three fields: 
    // The first field is private. 
    private string m_field = "String A";

    // The second field is public. 
    public string Field = "String B";

    // The third field is public const (hence also literal and static), 
    // with a default value. 
    public const string FieldC = "String C";

public class Myfieldattributes
    public static void Main()
        Console.WriteLine ("\nReflection.FieldAttributes");
        Demo d = new 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 = typeof(Demo);
        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);

    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);
