Get the value from Controller from another Controller in c#

Question

I have three controller classes in c#. Say AController, BController, CController. I used to set the value of private member of BController using AController.

public BController{
string test = "";
public BController(string input)
{
this.test = input;
}
}

How can I access the test from CController.

Any approach rather then assigning the member as static variable

Perhaps, you have mistaken the logic? Could you provide more code and some more info about your needs? — noobed, Oct 29 '14 at 14:21

You can return a redirect to CControllerAction.

public class BController()
{
    public ActionResult BControllerAction()
    {
         return RedirectToAction("CControllerAction", "CController", new { param = "some string" })
    }
}

public class CController()
{
    public ActionResult CControllerAction(string param)
    {
         if(!String.IsNullOrEmpty(param))
         {
            //do smth
         }
    }
}

You can get and set the value of a private field using the Properties pattern

public string TestB {
    get {return this.test;}
    set {this.test = value;}   
}

Your question does not specify the technology you are using. Hence my first suggestion is based on plain C# class.

The test property is a private field and cannot be accessed outside the class. You can expose it via a property. You can make the field as internal if you are going to access it with the current assembly. Have a look at Access Modifier for more informaiton. I would suggest you to use a property as it give you more control.

private string test;
public string Test
{
 get{return test;}
 set{test=value'}
}

If you are using MVC then you can make use of TempData. TempData is a dictionary derived from TempDataDictionary class. It is used to store data which is only needed for the following request. For more information, refer TempData
