小编Ale*_*ec.的帖子

我需要一个要求输入时间的弹出窗口，我认为可以使用Alertview，但是我不知道从哪里开始将时间选择器嵌入AlertView。

除非有更好的方法可以这样做？

下面的存储过程按预期正常工作.如果"FleetBarcode"存在则返回True,否则返回False.

但是,当它返回时,它显示如下

(no column name)
     True

我的问题是我需要"No Column Name"部分来定义列名.到目前为止尝试了下面的方法,它给'True'字段一个别名.

感谢您的时间.

ALTER proc [dbo].[usp_getjobs]

@barcode as nvarchar(20)


as
SELECT CASE WHEN EXISTS(
SELECT 
[FleetBarcode],
[Deleted]

FROM w_DeliveryItems


 WHERE FleetBarcode = @barcode
 AND Deleted != 1
)
THEN (SELECT  'True'  'Exist')
ELSE (SELECT 'False' 'Exist')


END

我有一些将文件（在本例中通常为 .csv）上传到远程 FTP 站点的代码

代码

    try
    {
        /* Create an FTP Request */
        ftpRequest = (FtpWebRequest)FtpWebRequest.Create(host + "/" + remoteFile);
        /* Log in to the FTP Server with the User Name and Password Provided */
        ftpRequest.Credentials = new NetworkCredential(user, pass);
        /* When in doubt, use these options */
        ftpRequest.UseBinary = false;
        ftpRequest.UsePassive = false;
        ftpRequest.KeepAlive = true;
        /* Specify the Type of FTP Request */
        ftpRequest.Method = WebRequestMethods.Ftp.UploadFile;
        /* Establish Return Communication with the FTP Server */
        ftpStream = …

我有以下数据类，我曾尝试向其中添加AdditionalCharge数组，但得到标题中指定的错误。

下面是AdditionalCharge类和包含额外费用的FundingRequest类。

我不确定自己做错了什么。

class AdditionalCharge{
    var ItemDescription = ""
    var ItemValue:String = ""
}

class FundingRequest: Codable {
let dispatcherName, loadReference, origin, destination: String
let userID: String, applicationID: String
let pickedUp, droppedOff: String
let driverFirstName, driverLastName: String
let grossTruckPay,fundingMethod, comments: String
let advancesTaken: Bool
let rateConfirmation, billOfLading, lumperReceipt: [String]
let salesTicket: [String]
let debtorID: String
let additionalCharges = [AdditionalCharge]()
enum CodingKeys: String, CodingKey {
    case dispatcherName = "DispatcherName"
    case loadReference = "LoadReference"
    case origin = "Origin"
    case destination = "Destination" …

我有以下代码

    private void bgwSendMail_DoWork(object sender, DoWorkEventArgs e)
    {
        DataSet ds = getMailToSend();
        DataTable table = ds.Tables[0];
        {
            foreach (DataRow row in table.Rows)
            {
                {
                    string attachment1 = ds.Tables[0].Rows[0]["Attachment1"].ToString();
                    string attachment2 = ds.Tables[0].Rows[0]["Attachment2"].ToString();
                    string attachment3 = ds.Tables[0].Rows[0]["Attachment3"].ToString();
                    string attachment4 = ds.Tables[0].Rows[0]["Attachment4"].ToString();
                    string mailTo = ds.Tables[0].Rows[0]["EmailTo"].ToString();
                    string mailSubject = ds.Tables[0].Rows[0]["EmailSubject"].ToString();
                    string mailBody= ds.Tables[0].Rows[0]["EmailBody"].ToString();
                    string uid = ds.Tables[0].Rows[0]["uid"].ToString();

                    if (String.IsNullOrEmpty(attachment1))
                    {
                        //TODO Send Email Straight away ignore rest

                    }
                    else
                    {
                        if (!String.IsNullOrEmpty(attachment1))
                        {
                            bool attachment1Exists = checkFileExists(attachment1);
                            if (attachment1Exists == false)
