类用作方法中的变量或参数 [英] class use as a variable or parameter in method

问题描述

我是.net编程的新手.
我想知道当我创建一个像user这样的类，然后再创建一些其他类时， 我正在创建函数或方法的页面，我可以将该类用作变量或参数，如method is
公用字符串validate(User user)
{

}

我的课是

i am new in .net programming.
i want to know that when i create a class like user and then some other
page i am creating a function or method can i use that class as variable or parameter like method is
public string validate(User user)
{

}

while my class is

using System;
using System.Collections.Generic;
using System.Text;
namespace MailingList {
    public class User {
        private string _userName ;
        private string _password;
        private int _oid;

        public User() {
            _userName = string.Empty;
            _password = string.Empty;
            _oid = 0;
        }
        public string UserName {
            get { return _userName; }
            set { _userName = value; }
        }
        public int OID {
            get { return _oid; }
            set { _oid = value; }
        }
        public string Password {
            get { return _password; }
            set { _password = value; }
        }

    }

}

这意味着什么，如果有人理解我的问题请我解释一下，我将无法解释我想知道的事情.
谢谢

推荐答案

您不要将类用作参数.您可以使用类类型作为参数类型，并使用类的实例作为参数.

简而言之，这很好.

You don''t use the class as a parameter. You use the class type as the parameter type and an instance of your class as the parameter.

In short, this is fine.

public string validate(User user)<br />
{<br />
<br />
}

User 是您的课程，user 是此类的实例.

User is your class and user is an instance of this class.
