如何确定适合固定尺寸2D空间的任意数量的等方的大小？(How do I determine the size of an arbitrary number of equal squares to be fit into an fixed size 2D space?)

 啊，我发现了问题。 
 
 问题是当我需要GebruikerIsIngelogd();函数时，我创建了一个新的BLSecurity实例GebruikerIsIngelogd(); 
 
 所以我在我的Load函数中设置了部分 
 
protected void Page_Load(object sender, EventArgs e) {
    BLSecurity BLSecurity = new BLSecurity();

    BLSecurity.Gebruiker = (wk_Gebruiker)Session["gebruiker"];

    SomeFunction();
}
 
 并在函数SomeFunction(); 我需要那些方法。 
 
 SomeFunction（）; 
 
private void SomeFunction(){
    BLSecurity BLSecurity = new BLSecurity();      //here lies the problem

    if(BLSecurity.IsLoggedIn()){
        ...
    } else {
        ...
    }
}
 
 所以问题是DoSomething()中BLSecurity的这个新实例 
 
 解决方案是将实例移到Page_Load（）之上 
 
public partial class WineKeeper : System.Web.UI.MasterPage {

    private BLSecurity BLSecurity = new BLSecurity();

    protected void Page_Load(object sender, EventArgs e) {
        BLSecurity.Gebruiker = (wk_Gebruiker)Session["gebruiker"];
        SomeFunction();
    }
}
 
 这样我就不会被覆盖，这会导致null。 

Ah, I found the problem.
 
The problem was that I created a new instance of BLSecurity when I needed the function GebruikerIsIngelogd();
 
So I had in my Load function the set part
 
protected void Page_Load(object sender, EventArgs e) {
    BLSecurity BLSecurity = new BLSecurity();

    BLSecurity.Gebruiker = (wk_Gebruiker)Session["gebruiker"];

    SomeFunction();
}
 
And in the function SomeFunction(); I needed those methods.
 
SomeFunction();
 
private void SomeFunction(){
    BLSecurity BLSecurity = new BLSecurity();      //here lies the problem

    if(BLSecurity.IsLoggedIn()){
        ...
    } else {
        ...
    }
}
 
So the problem is this new instance of BLSecurity in DoSomething()
 
The solution was to move the instance above the Page_Load()
 
public partial class WineKeeper : System.Web.UI.MasterPage {

    private BLSecurity BLSecurity = new BLSecurity();

    protected void Page_Load(object sender, EventArgs e) {
        BLSecurity.Gebruiker = (wk_Gebruiker)Session["gebruiker"];
        SomeFunction();
    }
}
 
This way I won't be overridden which would result in null.
