i am using this code to get database and convert it into JSON and display in android through web services.

public string Method()
{
        DataTable dt = new DataTable();
        using (SqlConnection con = new SqlConnection(@"Connection_string"))
        {
            using (SqlCommand cmd = new SqlCommand("_query_", con))
            {
  con.Open();
  SqlDataAdapter da = new SqlDataAdapter(cmd);
  da.Fill(dt);
  System.Web.Script.Serialization.JavaScriptSerializer serializer 
            = new System.Web.Script.Serialization.JavaScriptSerializer();
   List<Dictionary<string, object>> rows = new List<Dictionary<string, object>>();
                Dictionary<string, object> row;
                foreach (DataRow dr in dt.Rows)
                {
                    row = new Dictionary<string, object>();
                    foreach (DataColumn col in dt.Columns)
                    {
                        row.Add(col.ColumnName, dr[col]);
                    }
                    rows.Add(row);
                }
                return serializer.Serialize(rows);
            }
        }
}

In the same way if an android app gives a data then how would I be able to get that data and insert it into database?
