FieldInfo.IsPublic Property

Gets a value indicating whether the field is public.

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

public bool IsPublic { get; }

Property Value

Type: System.Boolean
true if this field is public; otherwise, false.

Implements

_FieldInfo.IsPublic

Public fields are accessible everywhere their corresponding classes are visible.

The IsPublic property is set when the FieldAttributes.Public attribute is set.

To get the IsPublic property, first get the class Type. From the Type, get the FieldInfo. From the FieldInfo, get the IsPublic property. If the field is other than public, it is protected and cannot be readily accessed. To access a nonpublic field, set the BindingFlags to NonPublic, specify either BindingFlags.Instance or BindingFlags.Static, and use this for the GetField method.

The following example returns a value indicating whether or not the field of the class is public or private.

using System;
using System.Reflection;


 // Make two fields. 
public 
    class Myfielda // private
{
    private string SomeField = "private field";
    public string Field
    {
        get{return SomeField;}
    }
}

public 
    class Myfieldb // public
{
    public string SomeField = "public field";
}

public 
    class Myfieldinfo
{
    public static int Main()
    {
        Console.WriteLine("\nReflection.FieldInfo");
        Myfielda Myfielda = new Myfielda();
        Myfieldb Myfieldb = new Myfieldb();

        // Get the Type and FieldInfo.
        Type MyTypea = typeof(Myfielda);
        FieldInfo Myfieldinfoa = MyTypea.GetField("SomeField", 
            BindingFlags.NonPublic|BindingFlags.Instance);
        Type MyTypeb = typeof(Myfieldb);
        FieldInfo Myfieldinfob = MyTypeb.GetField("SomeField");

        // Get and display the IsPublic and IsPrivate property values.
        Console.Write("\n{0}.", MyTypea.FullName);
        Console.Write("{0} - ", Myfieldinfoa.Name);
        Console.Write("{0}", Myfielda.Field);
        Console.Write("\n   IsPublic = {0}", Myfieldinfoa.IsPublic);
        Console.Write("\n   IsPrivate = {0}", Myfieldinfoa.IsPrivate);

        Console.Write("\n{0}.", MyTypeb.FullName);
        Console.Write("{0} - ", Myfieldinfob.Name);
        Console.Write("{0};", Myfieldb.SomeField);
        Console.Write("\n   IsPublic = {0}", Myfieldinfob.IsPublic);
        Console.Write("\n   IsPrivate = {0}", Myfieldinfob.IsPrivate);

        return 0;
    }
}
