Getting Database data into an array

thanks Rodick

It can't display the string tab after List, please add it.

Because you don't setting the array's length when you define it, So it occur error, You can do as this: string str=string.empty; while (drr1.Read()) { str+= drr1.GetValue(0).ToString()+","; } if(!string.isNullOrEmpty(str)) { str=str.Substring(0,str.Length-1); } string arrays=str.split(',');
