i tried for that also kiran...in that i got this error at same line when i took a string array.. like Object reference not set to an instance of an object. in this line arr[i] = dataGridView1.Rows[i].Cells[3].Value.ToString();

kiran kumar · Answer

you might have entered a no which exceeds the range of int better store the mobile no as string itself this will resolve your problem radhika

radhika ganta · Answer

kiran..am getting this error Value was either too large or too small for an Int32 in this line... arr[i] = Convert.ToInt32(dataGridView1.Rows[i].Cells[3].Value.ToString());
