Disable User Account in Active Directory using C# Code

Question

I have created c# Winform application. via which I can disable an active directory user account using C# code. I have added a textbox in which I can enter my AD username. But unable to figure how to link this textbox entry with below code?

private static void DiableADUserUsingUserPrincipal(string username)
{
    try
    {
        PrincipalContext principalContext = new PrincipalContext(ContextType.Domain); 
        UserPrincipal userPrincipal = UserPrincipal.FindByIdentity
                (principalContext, username);
        userPrincipal.Enabled = false;
        userPrincipal.Save();
        Console.WriteLine("Active Directory User Account Disabled successfully through UserPrincipal");
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex.Message);
    }
}

Try the following example:

C# CODE

First add an event click to your button:

// Button click event
private void btnDisableAcc_Click(object sender, EventArgs e)
{
    // When the user clicks the button
    String _ADUserName = textBox1.Text; // <-- The textbox you enter your username?

    // Call the method below 'DiableADUserUsingUserPrincipal'
    DiableADUserUsingUserPrincipal(_ADUserName); // <-- Pass in the user name via the local variable
}

Then define your method in the same class due to protection level is private otherwise if it is defined in another class / assembly ref then make the protection level public

// Private Method
private static void DiableADUserUsingUserPrincipal(string username)
{
    try
    {
        PrincipalContext principalContext = new PrincipalContext(ContextType.Domain);
        UserPrincipal userPrincipal = UserPrincipal.FindByIdentity
                (principalContext, username);
        userPrincipal.Enabled = false;
        userPrincipal.Save();

        MessageBox.Show("AD Account disabled for {0}", username);
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex.Message);
    }
}

To enable the account:

// Private Method with return type "Boolean" to determine if the method succeed or not.
private static bool EnableADUserUsingUserPrincipal(string username)
{
    try
    {
        PrincipalContext principalContext = new PrincipalContext(ContextType.Domain);
        UserPrincipal userPrincipal = UserPrincipal.FindByIdentity
        (principalContext, username);
        userPrincipal.Enabled = true;
        userPrincipal.Save();

        return true;
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex.Message);
    }

    return false;
}


private void button2_Click(object sender, EventArgs e)
{
    String _ADUserName = textBox1.Text; // <-- The textbox you enter your username?

    // Check if the account is enabled
    if (EnableADUserUsingUserPrincipal(_ADUserName))
    {
        MessageBox.Show("AD Account Enabled for {0}", _ADUserName );
        this.StatusTextBox.Text = "Account Enabled";
    }
}
