date converstion error?

Hi

string date = "TextBox3.Text";

string startdated = (Convert.ToDateTime(date)).ToString("yyyy/MM/dd");

or

string startdated = (Convert.ToDateTime(date)).ToString("yyyyMMdd");

Try changing this line:

  string bdate = Convert.ToDateTime(TextBox3.Text).ToString("yyyy-MM-dd"); 

to this:

  string bdate = Convert.ToDateTime(TextBox3.Text).ToString("yyyyMMdd");

 

hi try this:

i modified your code:

try
  {
  DateTime date = System.DateTime.Now;
  DateTime newDate = DateTime.ParseExact(TextBox3.Text, "dd-MM-yyyy", null);
  string s = newDate.ToString("MM-dd-yyyy");
  DateTime bdate = Convert.ToDateTime(s); 
 
  string str;
  string g="";
 


  if (RadioButton1.Checked == true)
  {
  g = "Male";
  }
  else
  {
  g = "Female";

  }
  FileUpload img = (FileUpload)imgUpload;
  Byte[] imgByte = null;
  if (img.HasFile && img.PostedFile != null)
  {
  HttpPostedFile File = imgUpload.PostedFile;
  imgByte = new Byte[File.ContentLength];
  File.InputStream.Read(imgByte, 0, File.ContentLength);
  }
  str = "insert into Student values('" + txtName.Text + "','"+bdate + "','" + g.ToString() + "','" + txtAddress.Text + "'," + ddlstate.SelectedValue + "," + ddlcity.SelectedValue + ",'" + DropDownList1.SelectedItem.Text + "','" + txtUserName.Text + "','" + TextBox1.Text + "','" + DropDownList2.SelectedItem.Text + "','" + DropDownList3.SelectedItem.Text + "','" + TextBox7.Text + "','"+imgByte.ToString()+"','" + date + "','false')";
  Int64 i;
  i = ObjConn.ExecuteNonQuery(str);
  if
  (i > 0)
  {
  Label1.Text = "Record Inserted Successfully!!!";
  Label1.ForeColor = System.Drawing.Color.Green;
  txtName.Text = "";
  TextBox3.Text = "";
  RadioButton1.Checked = false;
  RadioButton2.Checked = false;
  txtAddress.Text = "";
  txtUserName.Text = "";
  TextBox1.Text = "";
  TextBox7.Text = "";


  }
  else
  {
  Label1.Text = "Error while Inserting data!!!";
  Label1.ForeColor = System.Drawing.Color.Red;
  }
  }
  catch(Exception ex)
  {
  throw ex; 
  }
