Enumerating WindowsIdentity Roles with Reflection


Windows Identity has some properties, but you must use reflection to enumerate the private GetRoles() method:




namespace CurrentUser

{

    using System;

    using System.ComponentModel;

    using System.Reflection;

    using System.Security.Principal;

    using System.Windows.Forms;

 

    public class Form1 : Form

    {

        private TextBox textBox1;

        private Container components = null;

 

        public Form1()

        {

            InitializeComponent();

        }

 

        protected override void Dispose(bool disposing)

        {

            if (disposing)

            {

                if (components != null)

                {

                    components.Dispose();

                }

            }

            base.Dispose(disposing);

        }

 

        #region Windows Form Designer generated code

 

        private void InitializeComponent()

        {

            this.textBox1 = new System.Windows.Forms.TextBox();

            this.SuspendLayout();

            this.textBox1.Location = new System.Drawing.Point(8, 16);

            this.textBox1.Multiline = true;

            this.textBox1.Name = "textBox1";

            this.textBox1.Size = new System.Drawing.Size(320, 384);

            this.textBox1.TabIndex = 0;

            this.textBox1.Text = "textBox1";

            this.AutoScaleBaseSize = new System.Drawing.Size(5, 13);

            this.ClientSize = new System.Drawing.Size(344, 414);

            this.Controls.Add(this.textBox1);

            this.Name = "Form1";

            this.Text = "Form1";

            this.Load += new System.EventHandler(this.Form1_Load);

            this.ResumeLayout(false);

        }

 

        #endregion

 

        [STAThread]

        private static void Main()

        {

            Application.Run(new Form1());

        }

 

        private void Form1_Load(object sender, EventArgs e)

        {

            WindowsIdentity id = WindowsIdentity.GetCurrent();

            Type idType;

            idType = id.GetType();

            object result =

                idType.InvokeMember("_GetRoles", BindingFlags.Static | BindingFlags.InvokeMethod |

                    BindingFlags.NonPublic, null, id, new Object[] {id.Token}, null);

            string[] roles = (string[]) result;

            int i;

            for (i = 0; i < roles.Length; i++)

                textBox1.Text += roles[i] + "\r\n";

        }

    }

}



-- You can paste the above directly into a Windows Form class to test it out.
