Powershell -Confirm:$Y

Hello Fellow programmers, can someone show me the way to pass -Confirm:$Y using a c# code. Here is my C# Code which doesn't accept the -Confirm parameter.

PowerShell powershell = PowerShell.Create();
PSCommand command = new PSCommand();
command.AddCommand("Remove-MailContact");
string DisplayName = "UniqueValue112";
command.AddParameter("Identity", DisplayName);
command.AddParameter("Confirm", true);

The equivalent powershell code is

Remove-MailContact -Identity $DisplayName -Confirm:$Y

Can someone tell me how to pass equivalent to -Confirm:$Y using C#?

You should use the following: 

command.AddParameter("Confirm", new SwitchParameter(false));

This should work fine :)

You want to set the value of -Confirm to false.

command.AddParameter("Confirm", false);

In PowerShell commands, -Confirm:$false is the correct way to do this.

The reason -Confirm:$y works is that $y is (usually) an undefined variable, which evaluates to $null, which becomes $false when cast to Boolean. Obviously, this will fail in mysterious and hard-to-debug ways if some part of your script sets the variable $y to a non-null value.

A note about the syntax: -Parameter:$value is equivalent to -Parameter $value for most PowerShell parameters. The former is required for [switch] parameters such as -Confirm, because they normally don't take a value, and thus will not bind to the next token on the command line.
