Validation field date required

Question

Dear fellow users, I'm trying to send an error message to the user, but only my Data logs are not working, could you please help me out? Note, I put breakpoints to compile my

application, but it does not fall within the code referring to Data, it was to work : /

 

This is the part of the code that is not falling on the breakpoint and not displaying the logs for the user:

private void setProcessInter (Process process, Interested party, DataRow line, int i)
{
    i = 4;
    i ++;
    try
    {
        if (! line.ItemArray [17] .ToString ().) Equals (""))
            processInterested.CodeSep = decimal.Parse (line.ItemArray [17] .ToString ());
        else
            processInterested.CodeSep = null;
        try
        {
            DateTime DateSep = DateTime.Parse (line.ItemArray [18] .ToString ());
            processInterested.DateSep = DateSep;
        }
        catch
        {
            logErro.Append ("The cell S" + (line ["index"]) + "must be filled with a date.");
            fileInvalidated = true;
        }
        try
        {
            DateTime DataEntrySefaz = DateTime.Parse (line.ItemArray [19] .ToString ());
            processInterested.DateInputSelf = DateEntrySelf;
        }
        catch
        {
            logErro.Append ("The T cell" + (line ["index"]) + "must be filled with a date.");
            fileInvalidated = true;
        }
        try
        {
            DateTime DateRequestPgto = DateTime.Parse (line.ItemArray [0] .ToString ());
            processInterestedDate  = DateRequisitionoPgto;
        }
        catch
        {
            logErro.Append ("cell A" + (row ["index"]) + "must be filled with a date.");
            fileInvalidated = true;
        }
        processInterested.Interested = interested;
        catch (Exception error)
        {
            fileInvalidated = true;
            logErro.Append (error.Message + "<br>");
        }
    }
