Question

所以基本上我想要的是将两个数字相加并求和或求和。

这是我的代码：

const string PropTag = "http://schemas.microsoft.com/mapi/proptag/";
var filter = "@SQL=" + "\"" + PropTag
         + "0x0037001E" + "\"" + " ci_phrasematch " + "\'" + strFilter + "\'";

Outlook.Table table = inbox.GetTable(filter, Outlook.OlTableContents.olUserItems);

while (!table.EndOfTable)            
{
        Outlook.Row nextRow = table.GetNextRow();
        try
        {
            Outlook.MailItem mi;
            try
            {
                string entryId = nextRow["EntryID"];
                var item = outlookNameSpace.GetItemFromID(entryId);
                mi = (Outlook.MailItem)item;
            }
            catch (InvalidCastException ex)
            {
                Console.WriteLine("Cannot cast mail item, so skipping. Error: {0}", e);                       
                continue;
            } 
            //Extract the attachments here and archive or reply - put your logic here
        }
        catch (Exception e)
        {   
            Console.WriteLine("An error occurred: '{0}'", e);
        }
 }

这是我尝试添加它们的部分。

if (isset($this->date_filed) && !empty($this->date_filed) && !empty($this->date_forwarded_to_cmt_contractor)) {
            $date_forwarded_to_cmt_contractor = Carbon::createFromFormat('Y-m-d', $this->date_forwarded_to_cmt_contractor);
            $date_filed = Carbon::createFromFormat('Y-m-d', $this->date_filed);
            $interval = $date_filed->diff($date_forwarded_to_cmt_contractor);
            $this->cst_to_cmt = $interval->format('%a' . ' ' . 'Days');

            if ($this->status == 'RECTI03') {
                $now = Carbon::now();
                $date_forwarded_to_cmt_contractor = Carbon::createFromFormat('Y-m-d', $this->date_forwarded_to_cmt_contractor);;
                $interval = $date_forwarded_to_cmt_contractor->diff($now);
                $this->cmt_to_current_date = $interval->format('%a' . ' ' . 'Days');

            }

            $this->date_filed_to_current_date = $this->cst_to_cmt + $this->cmt_to_current_date;

        }

但是我得到这个错误。为什么呢？：/

将类型转换为integer怎么样？

$this->date_filed_to_current_date = (int)$this->cst_to_cmt + (int)$this->cmt_to_current_date;

当您在字符串上使用逗号或其他任何非数字字符（例如,或-）时，您会收到通知格式不正确的数字遇到的值。最好在添加操作之前将其转换为整数类型。
