How can I get rid of extra characters in TextBox?

Question

The intent of this form is to retreive first a username then use that username to retreive an email address. it does get the address but it also retreives other characters as well. textbox3 ends up reading @{EmailAddress=first.last@domain.com}. I have tried trimming characters but that did not work.

Add-Type -Name Window -Namespace Console -MemberDefinition '
    [DllImport("Kernel32.dll")]
    public static extern IntPtr GetConsoleWindow();
    
    [DllImport("user32.dll")]
    public static extern bool ShowWindow(IntPtr hWnd, Int32 nCmdShow);'
    
    [Console.Window]::ShowWindow([Console.Window]::GetConsoleWindow(), 0)

There are two issues with your code:

As explained in a comment, you need to get the value from the EmailAddress property of your object, otherwise, because the .Text property value can only be a string, what you will see as a result is a string representation of a PSCustomObject.
The assignment of $User.Text is invalid and will produce an error unless you're not showing us your actual code. The $User variable not defined hence cannot have a .Text property. Trying to assign anything to it will produce an error such as:

The property 'Text' cannot be found on this object. Verify that the property exists and can be set.

How should your function to solve both issues:

function getacctname {
    $fname, $lname = $TextBox1.Text.Trim(), $TextBox2.Text.Trim()
    $TextBox3.Text = Get-ADUser -Filter "GivenName -eq '$fname' -and SurName -eq '$lname'" -Properties mail |
        Select-Object SamAccountName, mail |
        Out-Gridview -Title 'Windows Logon' -PassThru |
        Select-Object -ExpandProperty mail
}

As aside, I would recommend you to make $TextBox3 a ReadOnly TextBox:

$TextBox3.ReadOnly = $true
