                                HttpMethod="POST",
                                OnFailure = "function() { alert('fail'); }",
                                OnSuccess = "function() { alert('success'); }" 
                            })%> 
							
	}

 CustomerController
 
  [AcceptVerbs(HttpVerbs.Post)]
        public ActionResult Create(FormCollection formCollection)
        {

            clsCustomer objcustomer = new clsCustomer();
            clsSession objSession = new clsSession();


            objcustomer.Fname = formCollection["Fname"];  --> NULL 
            objcustomer.Lname = formCollection["Lname"]; --> NULL
			
			}

I want to create upload file to the server drive c. But there is user credentials require to access the server file path. So i use this code in app.config

<configuration>
       ....
     <appSettings>
       <add key="DocumentVault" value="\\10.100.100.10\C$\SomePath\SomeWhere\Else\"/>
     </appSettings>
    ....
</configuration>
How to add the user credentials inside?
