Question

我运行代码并且它不会将它立即停止的值存储在loadedfromscreen中。它应该做的是一个多页应用程序表单，它将把值重新输入到下一个表单后面按钮上的texbox。

ASP.net代码太长而无法发布，但基本上只是texbox和dropbox。如果需要我可以发布它，但主要问题是90％肯定是C＃代码。

更新：当我说停止它继续代码但不会运行字典方法...我已经放置了箭头，方法停止在DICTIONARY ONLY

C＃：

public partial class employment_driversapplication_personalinfo : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
    Dictionary<string, string> DriversApplicationData = (Dictionary<string, string>) Session["DriversApp"];

    try
    { 



            if (Page.IsPostBack)
            {
                LoadMemoryFromScreen(DriversApplicationData);
            }
            else
            {
                LoadScreenFromMemory(DriversApplicationData);
            }
              }

    catch //(Exception ex)
    {
       // throw new Exception("Exception occured in employment_driversapplication_personalinfo.aspx - Page_Load" + ex.Message);
    }
    finally
    {


    }
}

Answer 1

尝试这样的事情：

 private void LoadMemoryFromScreen()
    {    
     Dictionary<string, string> driver = new Dictionary<string, string>();
     driver.Add("position", position.Text);
     driver.Add("othervalue",value.Text); ///etc..
     Session["dict"] = driver;
    }

然后，如果您想要访问字典中的值，请使用以下内容：

var dict = (Dictionary<string, string>)Session["dict"];

问题在于你将不得不使用dict.GetElementAt(index)来检索值，我认为这不是一个很好的方法。

这会有效，但我有点不明白你为什么要用字典来做这件事。我假设您只在页面上加载1个人的数据？然后你也可以创建一个包含其中所有属性的类，然后你就可以传递它而不是使用这个字典/会话hack。

public class DriversApplicationData
{
public string position {get;set;}
public string firstname {get;set;}
//etc
}

然后，您可以执行类似

的操作

DriversApplicationData data = new DriversApplicationData();
data.position = position.Text;
data.firstname = fname.Text;

这将更容易维护和检索/插入值。

字典停在loadfromscreen
