C # MVC step-by-step operations

1. Establish homecontroller class and inherit asynccontroller

The token generation is as follows:

View code

   Public   Class Homecontroller: asynccontroller
{
 Public   Void Indexasync ()
{
Viewbag. Message = "  Welcome to ASP. net mvc!  " ;
Asyncmanager. outstandingoperations. increment ();
 VaR Task = task. Factory. startnew () => dostuff ( "  Some other stuff  " ));
Task. continuewith (t =>
{
Asyncmanager. Parameters [ "  Model  " ] = T. result;
Viewbag. Message = T. result;
Asyncmanager. outstandingoperations. decrement ();
});

}
 Private  String Dostuff ( String Input)
{
Thread. Sleep ( 5000 );
 Return Input;
}
 Public Actionresult indexcompleted ( String Model)
{
 Return View ();
}

}

2. The method indexasync for defining the specific step is also Acton. Note that. The method must return void.

The preceding method name is index + asnc. You must add asnc.

In this method, add a processing method. In this example

VaR task = task. Factory. startnew () => dostuff ("some other stuff "));
Task. continuewith (t =>
{
Asyncmanager. Parameters ["model"] = T. result;
Viewbag. Message = T. result;
Asyncmanager. outstandingoperations. decrement ();
});

3. Start in the next step

Asyncmanager. outstandingoperations. increment ();

4. End of the processing process

Asyncmanager. outstandingoperations. decrement ();

5. Variable Volume Changes

Asyncmanager. Parameters ["model"] = T. result;

Among them, the model is the variable name of the volume to be renewed.

In the same way, you can also use the data storage method in the collection, or modify the volume, for example, viewbag. Message = T. result;

6. After completing the steps, return the data volume indexcompleted

Including region index + completed

Such as this method

Public actionresult indexcompleted (String Model)
{
Return view ();
}

In this example, the model parameter number is the value of asyncmanager. Parameters ["model"] = T. Result; generated bytes.

If asyncmanager. Parameters defines a variable, then adding it to the parameter data of this method will lead over.

Data in the same collection is shared.

7. Using this collection method is

Home/Index
