我收到错误

  

“已添加具有相同键的项目”

随机生产。如果我在本地执行以下代码我没有得到问题。需要解决此问题的建议。

//check for whether Midas.DAB is Enabled in the App.Config File
if (ProcessMidasDab)
{                    
    var dvFilteredMidasDabDetails = new DataView(dtMidasDabandSurgDetails) {
    RowFilter = "not (LastReceivedOnForDAB is null)" };

    dtCmMidasDabAlerts.Columns.Add("ClientID");
    dtCmMidasDabAlerts.Columns.Add("LastFileReceivedDate");
    dtCmMidasDabAlerts.Columns.Add("SendingSystem");    

    //Get the Cut-off time for Midas.DAB from the App.config.
    var timeStamp = ConfigurationManager.AppSettings["TimeLapseforMidasDABinhrs"];

    //Logic to check the Feed for Midas.DAB
    foreach (DataRowView dv in dvFilteredMidasDabDetails)
    {
        midasDabClientList.Add(Convert.ToInt32(dv["ClientID"]));
        var timeDifference =
            (DateTime.Now - Convert.ToDateTime(dv["LastReceivedOnForDAB"])).TotalHours;
        if (timeDifference > Convert.ToDouble(timeStamp))
        {
            var drNewRow = dtCmMidasDabAlerts.NewRow();
            drNewRow["ClientID"] = dv["ClientID"];
            drNewRow["LastFileReceivedDate"] = dv["LastReceivedOnForDAB"];
            drNewRow["SendingSystem"] = "Midas.DAB";
            dtCmMidasDabAlerts.Rows.Add(drNewRow);
        }
    }

    dabclients = midasDabClientList;
}

Answer 1

你有两次分配这个

    drNewRow["Clientid"] = 12;
    drNewRow["ClientID"] = dv["ClientID"];

请删除此

drNewRow["Clientid"] = 12;

并且您还有两次分配此

dtCmMidasDabAlerts.Columns.Add("ClientID");
