C# – .NET Class Properties – Setter with parameter

cgetter-setternet

One of the nice features of .net is class Properties – wrapping gettter and setter of class field (which is private, but accessor methods are ussualy public). From outside of a class this Property looks as one field and does not flood intellisense with nomber of getters and setters.

Usual syntax is

private bool _isReadOnly;
public bool IsReadOnly
{
    get { return _isReadOnly; }
    set { _isReadOnly = value; }
}

or for implicit declaration it is

public bool IsReadOnly
{
get;
set;
}

This is very nice, both accessors can have even different access modifiers, eg. private setter.

My question is: does .NET support setters or getters with parameters? Like to have setter with two parameters – for example – one is value to set and other is bool which indicates something like "notify listeners about change" or "do not overwrite old value if newer value fails check" or something like that. Parameter for getter could be some option to format output or whether returned value should be clone of old etc.

Thank you. I do dot need it for any particular goal to achieve, so no need to post workarounds, i just wonder if there is something like this in .net Property.

VB.NET supports parameters on properties.

C# doesn't.

C# – Sending email in .NET through Gmail

Be sure to use System.Net.Mail, not the deprecated System.Web.Mail. Doing SSL with System.Web.Mail is a gross mess of hacky extensions.

using System.Net;
using System.Net.Mail;

var fromAddress = new MailAddress("from@gmail.com", "From Name");
var toAddress = new MailAddress("to@example.com", "To Name");
const string fromPassword = "fromPassword";
const string subject = "Subject";
const string body = "Body";

var smtp = new SmtpClient
{
    Host = "smtp.gmail.com",
    Port = 587,
    EnableSsl = true,
    DeliveryMethod = SmtpDeliveryMethod.Network,
    UseDefaultCredentials = false,
    Credentials = new NetworkCredential(fromAddress.Address, fromPassword)
};
using (var message = new MailMessage(fromAddress, toAddress)
{
    Subject = subject,
    Body = body
})
{
    smtp.Send(message);
}

Additionally go to the Google Account > Security page and look at the Signing in to Google > 2-Step Verification setting.

If it is enabled, then you have to generate a password allowing .NET to bypass the 2-Step Verification. To do this, click on Signing in to Google > App passwords, select app = Mail, and device = Windows Computer, and finally generate the password. Use the generated password in the fromPassword constant instead of your standard Gmail password.
If it is disabled, then you have to turn on Less secure app access, which is not recommended! So better enable the 2-Step verification.

C# – How to escape braces (curly brackets) in a format string in .NET

For you to output foo {1, 2, 3} you have to do something like:

string t = "1, 2, 3";
string v = String.Format(" foo {{{0}}}", t);

To output a { you use {{ and to output a } you use }}.

Or now, you can also use C# string interpolation like this (a feature available in C# 6.0)

Escaping brackets: String interpolation $(""). It is new feature in C# 6.0.

var inVal = "1, 2, 3";
var outVal = $" foo {{{inVal}}}";
// The output will be:  foo {1, 2, 3}
