A ref or out argument must be an assignable variable

Question

I\'m coding an application which can make a reverse proxy connection but I have a problem! The error is here: new Form1.ProxyConfig()

When I try to run

Answer 1

You cannot create a variable and pass it as a reference at the same time like you're doing there. Try this:

var config = new Form1.ProxyConfig()
{
    pclient_port = form2.ClientPort,
    pp_start = form2.LocalStartPort,
    pp_end = form2.LocalEndPort
};

int num1 = Form1.ProxyListenerStart( ref config, ref this._PN );

The reason is that it really wouldn't make any sense, consider the following scenario:

if( int.TryParse( "123", out new int() ) )
{
    // there's no way for us to actually use the value TryParse stored
    // into the out parameter, since it doesn't have a name
}
