Question

我没有从字符串中获取价值。

例如：

public static void ticket(string ticketName) // ticketName = "testTicket"
{
   string abc = ticketName; // result : abc null
}

有人可以帮助我，但我被困在它上将近2天

这是真实的代码

namespace FirstOutlookAddIn

{ public partial class lblSubject：Form { Outlook._Explorer currentExplorer = null;

    private string Conversation_ID;
    private string subject;
    private string senderName;
    private string senderEmail;
    private string incident;
    private DateTime creationDate;


    public lblSubject()
    {
        InitializeComponent();
        Outlook.Application myAPP = new Outlook.Application();
    }



    private void button3_Click(object sender, EventArgs e)
    {
        Outlook.Application myAPP = new Outlook.Application();

        Outlook.MAPIFolder selectedFolder =
            myAPP.Application.ActiveExplorer().CurrentFolder;
        String expMessage = "Your current folder is "
            + selectedFolder.Name + ".\n";
        String itemMessage = "Item is unknown.";
        try
        {
            if (myAPP.Application.ActiveExplorer().Selection.Count > 0)
            {
                Object selObject = myAPP.Application.ActiveExplorer().Selection[1];
                if (selObject is Outlook.MailItem)
                {
                    Outlook.MailItem mailItem =
                        (selObject as Outlook.MailItem);
                    itemMessage = "The item is an e-mail message : Entery ID:"+ mailItem.EntryID+ " Conversation ID" + mailItem.ConversationID;
                    Conversation_ID = mailItem.ConversationID;
                    //mailItem.Display(false);


                    // Grab the Body
                   //txtBody.Text = mailItem.Body;
                   rIncident.Text = mailItem.Body;
                   incident = mailItem.Body;
                   senderName = mailItem.SenderName;
                   senderEmail = mailItem.SenderEmailAddress;
                   creationDate = mailItem.CreationTime;
                   Conversation_ID = mailItem.ConversationID;
                    // Sender Name
                    lblSenderName.Text = mailItem.SenderName;
                    // Sender Email
                    lblSenderEmail.Text = mailItem.SenderEmailAddress;
                    // Creation date
                    lblCreationdate.Text = mailItem.CreationTime.ToString();
                }
    }



    private void lblSubject_Load(object sender, EventArgs e)
    {
        cboUsers.DataSource = Requetes.userliste();
        cboPriority.DataSource = Requetes.priorityliste();
    }



    private void btnCreateTicket_Click(object sender, EventArgs e)
    {
        string userNom = cboUsers.SelectedItem.ToString();
        string priorityNom = cboPriority.SelectedItem.ToString();
        string convoID = Conversation_ID;

        Requetes.saveTicket(userNom, priorityNom, subject,
            senderName, senderEmail, incident, convoID, creationDate);

    }



}

}

问题与Classrequete

有关

例如 if conversationID = "FFF1614651616fssd";t.Ticket_ConversationID = conversationID; // in debuget it shows conversationID is equal to "FF.....ssd" but t.Ticket_ConversationID is null：（（（（（（（ `

希望有人可以帮助我。很抱歉这里的代码太多了

Answer 1

我猜你试图调用ticket（）方法，但是你没有将参数传递给ticket（“testTicket”），或者当你试图调用ticket（value）时，你的变量可能没有从源代码获得价值，我我很确定。一切都很直接。

尝试遵循它：

public void SomeEvent()
{
   string value = "testTicket";
   ticket(value);
}

public static void ticket(string ticketName) // ticketName = "testTicket"
{
   string abc = ticketName; // result : abc null
}

祝你好运。
