Optimize Viewstate and Enum

  • Статья

In Asp.Net , When we use custom enumerations , and store them in the ViewState as Enum Text (Single or Married),
for eg.

 enum MyStatus {

Single = 0,

Married

}

The FullTypeName, i.e, name of the Type, the assembly Name, Strong name public key,

culture etc are stored in the viewstate. takeus up Almost 200 to 300 bytes

so it is always advised to cast it to integer before storing it in the viewstate

and parse it back to Enum while reading it.
eg.

 public MyStatus Status

{

get{ (MyStatus) Enum.Parse(typeof(MyStatus) , ViewState["MyStatus"]) ;

}

set

{

 ViewState["MyStatus"]  = (int) value;

}

}

    Premature optimization is the root of all evil. IMO this is just like the ORM n+1 problem... overrated.

    This doesn't work. Enum.Parse is expecting a string as the second parameter. ViewState[whatever] is an object.
