什么'；在c#中设置类初始化公共变量的正确方法是什么？

我已经用c#创建了底部的类。webservices引用该类以确定用户访问，如下所示：

[WebMethod]
public List<FAFSA> getFAFSA(string pageID)
{
    formValues fv = new formValues();
    string personID = fv.personID;
    List<FAFSA> lf = new List<FAFSA>();

    if (fv.secBlur == "no_secBlur")
    {
        FAFSA f = new FAFSA();
        f.fafsaCheck = "0";
        lf.Add(f);
    }

    ...
}

---

如果为任何类提供静态、公共值，则在完成任何访问之前，将调用所谓的“静态”（或类型）构造函数来执行初始化工作：

进行初始化或定义默认值的另一种常见方法是使用Factory模式。另外，XNA中的图形类必须根据您是运行X-Box还是PC进行调整，因此它使用工厂模式

关于coruse与Web（任何内容）的关系，存在可变范围的整个问题，即使是静态的问题。更不用说局部变量了

public class formValues : System.Web.Services.WebService
{
    public string userName = getUserName();
    public string firstName = getFirstName();
    public string personID = getPersonID();
    public int fafsa = 0;
    public int staff = 0;
    public string secBlur = getSecBlur();

    private static string getUserDataString(int ix)
    {
        string retValue = "";

        if (HttpContext.Current.Request.IsAuthenticated)
        {
            HttpCookie authCookie = HttpContext.Current.Request.Cookies[FormsAuthentication.FormsCookieName];

            if (authCookie != null)
            {
                FormsAuthenticationTicket ticket = FormsAuthentication.Decrypt(authCookie.Value);

                if (ticket != null)
                {
                    string[] userData = { "" };

                    char[] delimiterChar = { '|' };
                    userData = ticket.UserData.Split(delimiterChar);
                    if (userData.Length > 1)
                        retValue = userData[ix];
                    else
                    {
                        FormsAuthentication.SignOut(); 

                        string redirUrl = "/DMC/loginNotFound.html";
                        HttpContext.Current.Response.Redirect(redirUrl, false);
                    }
                }
            }
        }

        return retValue;
    }

        string cf = System.Configuration.ConfigurationManager.ConnectionStrings["DistrictAssessmentDWConnectionString"].ConnectionString;

        SqlConnection connection = new SqlConnection(cf);
        SqlCommand command = new SqlCommand(mySQL, connection);

        command.Parameters.AddWithValue("@personID", getUserDataString(0));

        connection.Open();

        SqlDataReader dr = command.ExecuteReader();
        DataTable dt = new DataTable();
        dt.Load(dr);
        connection.Close();

        if (dt.Rows.Count > 0)
        {
            if (dt.Rows[0]["secBlur"].ToString() == "1")
                secBlur = "secBlur";

            fafsa = Convert.ToInt32(dt.Rows[0]["fafsa"]);
            staff = Convert.ToInt32(dt.Rows[0]["staff"]);
        }

        return secBlur;
