Respected All,
 
I am new to .net core and am stuck at one point in my development.
 
I have requirement for developing app using asp.net core mvc, web api with token based google-gmail authentication.
 
I have done coding with simple google authentication but not sure about token based web api development.
 
I have gone through so many article but not found proper flow with my requirements.
 
And also i have to use sqlite db.
 
Please help me out for the solution.

In the dropdownlist selection changed event

if (DropDownList1.SelectedIndex != 0)
{
string strValue = string.Empty;
SqlConnection con = new SqlConnection("Data Source=myServerAddress;Initial Catalog=myDataBase;Integrated Security=SSPI;");
SqlCommand cmd = new SqlCommand(" select Empname from Employee where empid='"+ DropDownList1.SelectedValue.ToString()+"'", con);
con.Open();
strValue = (string)cmd.ExecuteScalar();
con.Close();
TextBox1.Text = strValue;
}
