导航时全局变量重置

Question

我在CURRENTUSER中有一个变量GlobalVariable.cs：

GlobalVariables.cs

在LoginPage.xaml.cs：

中对其进行了修改

LoginPage.xaml.cs

导航到ConceptForm.xaml.cs后，它会被调用几次：

public partial class ConceptForm : Page
{
    //Default Constructor
    public ConceptForm()
    {
        //Initializing the Default Constructor
        InitializeComponent();

        //Debugging Code To Indicate Current Signed In User
         string cU = GlobalVariables.**CURRENTUSER**.ToString();
         MessageBox.Show(cU);

        //Get Current User Name Based On login credentials 
        campaignProductManagerBox.Text = campaignProductManagerBox.Text + GlobalVariables.USERS[GlobalVariables.**CURRENTUSER**, 2];

        //Get Current Date And Time
        DateTime dAT = DateTime.Now;
        dateAndTimeBox.Text = dateAndTimeBox.Text + dAT;

        //Get Current User Phone Number Based On Login Credentials
        contactNumberBox.Text = contactNumberBox.Text + GlobalVariables.USERS[GlobalVariables.**CURRENTUSER**, 4];

        //Conditional to determine Quarter of the Year Based On Date And Time Gotten Earlier
        //If current month is January, February or March
        if ( dAT.Month == 1 || dAT.Month == 2 || dAT.Month == 3 )
        {
            //It is the First Quarter of the Year
            conceptIdBox.Text = conceptIdBox.Text + "Q1_";
        }

        //If current month is April, May or June
        else if (dAT.Month == 4 || dAT.Month == 5 || dAT.Month == 6 )
        {
            //It is the Second Quarter of the Year
            conceptIdBox.Text = conceptIdBox.Text + "Q2_";
        }

        //If current month is July, August or September
        else if (dAT.Month == 7 || dAT.Month == 8 || dAT.Month == 9)
        {
            //It is the Third Quarter of the Year
            conceptIdBox.Text = conceptIdBox.Text + "Q3_";
        }

        else
        {
            //It is the Fourth Quarter of the Year
            conceptIdBox.Text = conceptIdBox.Text + "Q2_";
        }

        //Get Current User Department Based On Login Credentials
        conceptIdBox.Text = conceptIdBox.Text + GlobalVariables.USERS[GlobalVariables.**CURRENTUSER**, 3] + "_0";
    }

但是，导航到CURRENTUSER后，0的值重置为ConceptForm.xaml.cs

通过在LoginPage.xaml.cs和ConceptForm.xaml.cs中进行一些调试，我得到了进一步的证据，告诉我点击Login上的LoginPage.xaml.cs，CURRENTUSER的值根据提供的登录凭据，1是正确的，但在加载ConceptForm.xaml.cs时，它会告诉我CURRENTUSER现在是0，这是不正确的。

这导致错误的信息显示在ConceptForm.xaml.cs上CURRENTUSER依赖于显示的信息。

我做错了什么，拜托？

提前谢谢！
