c# - change cell in datagridview to empty value -


i have method change cell in datagridview , works fine when rewrite text (string) .
want example rewrite email empty value , dont know how this.
i can rewrite email email (string string)

method change cell :

public void changecellemail(int col, string[] emails)     {           string sep = ";";         string text = "";          foreach (datagridviewcell cell in datagridview1.selectedcells)         {               (int = 0; < emails.length ;i++)             {                  if (emails[i].tostring().trim() != "")                 {                       text = text + emails[i] + sep ;                     datagridview1.rows[cell.rowindex].cells[col].value = text;                 }             }          }      }

the calling code of method is

            string mail = txtbox1.text;             string mail1 = txtbox2.text;             string mail2 = txtbox3.text;             string mail3 = txtbox4.text;             string mail4 = txtbox5.text;              string[] mails = new string[] { mail, mail1, mail2, mail3, mail4 };               frm1.changecellemail(2, mails);             this.dispose();

thanks guys .

using following code can pass in 5 complete email address's of / "empty" , tempvar contain correct data.

public form1()     {         initializecomponent();          const string mail = "first";         const string mail1 = "second";         const string mail2 = "third";         const string mail3 = "";         const string mail4 = "fifth";          var mails = new string[] { mail, mail1, mail2, mail3, mail4 };          changecellemail(2, mails);     }       public void changecellemail(int col, string[] emails)     {         var sep = ";";         var text = "";         var tempvar = ""; //new temp variable (representing datagrid.value)          (int emaillist = 1; emaillist < 5; emaillist++)         {             (var = 0; < emails.length; i++)             {                  if (emails[i].trim() != "")                 {                     text = text + emails[i] + sep;                     tempvar = text;                 }                 else                 {                     tempvar = string.empty;                 }             }          }      }

check tempvar on each loop , you'll see referring to.

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
