C# Typecast to Enum from Request.Params

[SpecialKay]

Sorry if this is not the place for C#.

in short:

public enum MyEnum
{
One,
Two,
Three
};

page_load
{
MyEnum num = (MyEnum)Request .Params("number ");
}

assume the page is being called

www.mypage.com? number="One"

i get a simple "Error 7 Cannot convert type 'string' to 'MyEnum' .... "

Thanks in advance

Try converting "number" to System.Int32 then cast it as an enum.

Dont see how that would change anything. But i tried it anyway.
Same problem, unable to convert.

My solution:
Im sure there is a better way!

Here is my solution. Im sure there is a better way.

page_load
{
myEnum num = setState(Reques t.Params("numbe r");
}

private myEnum setState(string state)
{
switch(state)
{
case One:
return myEnum.One;

etc.
}
}

I forget where it is found (System.Enum or something?) That will give you an enum[] type deal that lets you itterate through your ENUMs like that, then you can compare the enum's .ToString(), which in your case is "one" "two" "three", and do a string comparison to deterimine if it's your enum.

See this post for more on enum enumeration:

Is this what you need?

string s = "FirstItem"
//Assume you have an enumeration called "MyEnum", of which each of the entries are FirstItem = 1; SecondItem = 2 etc etc.  You could find the item called "FirstItem" using the string and System.Enum.Parse...
MyEnum SelectedEnum = System.Enum.Parse(GetType(MyEnum), s)

Looks like it might work, i will try it out and let you know, thanks a bunch!

Thanks guys, you pointed me down the right path
the end result is

 
public void results(httpRequest Request)
{
  string state = request.params["number"];
 
  myEnum num = (myEnum)System.Enum.Parse(typeof(myEnum), state)
}

Oops, looks like my VB to C# translation skills are slipping... hehe. At least you got it sorted ;o)

GetType = typeof <committing to memory...>
