我已经在c#的底部创建了该类。 Webservices引用此类来确定用户访问权限,例如:
[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);
}
...
}
我正在尝试添加两个变量fafsa和staff。方法getSecBlur()从secBlur,fafsa和staff返回我数据库中的所有三个值。那么,如何设置此类,使SecBlur方法仅被调用一次,却填充我的所有三个变量,以便可以在Web服务调用中使用它们?它不能像现在那样工作,因为它说fafsa和staff必须是静态的,但是如果我将它们设为静态,则在webservices中它说必须使用实例引用来访问成员。
很抱歉,如果措辞不好,但我对此并不陌生,仍在尝试学习...
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;
}
private static string getUserName()
{
//This retrieves the person logged into windows/active directory
WindowsPrincipal wp = new WindowsPrincipal(WindowsIdentity.GetCurrent());
//string[] fullUsername = wp.Identity.Name.Split('\\');
string fullUsername = wp.Identity.Name;
return fullUsername;
}
private static string getFirstName()
{
string firstName = getUserDataString(1);
return firstName;
}
private static string getPersonID()
{
string personID = getUserDataString(0);
return personID;
}
private static string getSecBlur()
{
string secBlur = "no_secBlur";
string mySQL = "exec get_UserAdminStatus @personID";
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;
}
}

如果给任何类静态的,则在进行任何访问之前,将调用所谓的“静态”(或类型)构造函数进行初始化工作:https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/static-constructors
进行初始化或定义默认值的另一种常用方法是使用“工厂模式”。 Xfa中的Afaik图形类必须根据在X-Box或PC上运行而进行调整,因此它使用出厂模式。
与Web(任何东西)无关的是,整个范围都存在变量Scope,即使对于静态变量也是如此。局部变量要少得多。
