Generic function to output the values of an Enumeration

[DotNetNewbie]

Hi,
I want to create a method that takes in the type of a Enumeration,
passes in the Enumeration as an object, and then outputs the values
with checkboxes, and pre-checks the checkbox if that value is set in a
mask.

This is what I have so far that outputs the values as a checkbox, but
I need to pass in *any* mask so it can check if that value is set in
the mask, if yes, check the checkbox.

public static string EnumToCheckboxe s(Type enumType, string
namePrefix)
{
StringBuilder sb = new StringBuilder() ;
foreach (string item in Enum.GetNames(e numType))
{
string name = String.Format(" {0}-{1}", namePrefix,
item);

sb.Append(@"<li ><input type=""checkbox ""
name=""").Appen d(name).Append( @"""").Append(@ "
id=""").Append( name).Append(@" ""></li>");
sb.Append(item) ;
}
return sb.ToString();
}
What i'm thinking to do is:

public static string EnumToCheckboxe s(Type enumType, string
namePrefix, object mask)
{

StringBuilder sb = new StringBuilder() ;

(enumType)mask // ??????????????? ?

foreach (string item in Enum.GetNames(e numType))
{
string name = String.Format(" {0}-{1}", namePrefix,
item);

sb.Append(@"<li ><input type=""checkbox ""
name=""").Appen d(name).Append( @"""").Append(@ "
id=""").Append( name).Append(@" ""></li>");
sb.Append(item) ;
}


return sb.ToString();
}

Well, you´ve to learn a few thing about reflection.
Try it, it will probably help you.

What I would do is enumerate the Enum.GetValues( ) array instead of the
GetNames() array. Cast your mask and current value to int, and set the
checkbox based on that result.

You could of course parse the enumeration value name, going the other
direction. But I think it reads better starting with the value, and I
think that converting the value to a string (for use as the "name") is
slightly easier than converting the string to a value (though neither is
really that hard).

That worked great, thanks Pete!
