Saving Single Object¶
Blocking Method¶
Dictionary<string, object> result; result = Backendless.Data.Of( "TABLE-NAME" ).Save( Dictionary<string, object> );
public E Backendless.Data.Of<E>().Save( E entity );
Non-Blocking API¶
void Backendless.Data.Of( "TABLE-NAME" ).Save( Dictionary<string, object> entity, AsyncCallback<Dictionary<string, object>> responder )
public void Backendless.Data.Of<E>().Save( E entity, AsyncCallback<E> responder )
where:
Argument | Description |
---|---|
TABLE-NAME |
Name of the table where the object represented by System.Collections.Generic.Dictionary will be saved. |
E |
A .NET class of the data object to save. |
entity |
.NET object to persist, must be of type E or System.Collections.Generic.Dictionary (depending on the method used). |
responder |
a responder object which will receive a callback when the method successfully saves the object or if an error occurs. Applies to the non-blocking method only. |
Return Value¶
The blocking method returns the saved object. The non-blocking call receives the return value through a callback executed on the AsyncCallback
object.
Example¶
¶
Dictionary<string, object> contact = new Dictionary<string, object>(); contact[ "name" ] = "Jack Daniels"; contact[ "age" ] = 147; contact[ "phone" ] = "777-777-777"; contact[ "title" ] = "Favorites"; // save object synchronously Dictionary<string, object> savedContact; savedContact = Backendless.Data.Of( "Contact" ).Save( contact ); // save object asynchronously AsyncCallback<Dictionary<string, object>> callback; callback = new AsyncCallback<Dictionary<string, object>>( result => { // object has been saved }, fault => { // server reported an error } ); Backendless.Data.Of( "Contact" ).Save( contact, callback );
Consider the following class.
The following code saves a new instance of the Contact class:
using System; namespace com.mbaas { public class Contact { public String objectId { get; set; } public String Name { get; set; } public int Age { get; set; } public String Phone { get; set; } public String Title { get; set; } } }
Contact contact = new Contact(); contact.Name = "Jack Daniels"; contact.Age = 147; contact.Phone = "777-777-777"; contact.Title = "Favorites"; // save object synchronously Contact savedContact = Backendless.Data.Of<Contact>().Save( contact ); // save object asynchronously AsyncCallback<Contact> callback = new AsyncCallback<Contact>( result => { // object has been saved }, fault => { // server reported an error } ); Backendless.Data.Of<Contact>().Save( contact, callback );
