How would I write the following line in a more neat way?

if ( myDataType == "int" || myDataType == "smallint" )

something like this pseudocode:

if ( myDataType == ("int" || "smallint") )

Thanks,
Yannick Smits

Just off the top of my head, do you think the XOR operator would work? eg.

if(myDataType == ("int" | "smallint"))

perhaps in a switch statement?

switch (myDataType){

case "int":
case "smallint":
HandleIntegralTypes();
break;
case "varchar":
HandleVarChar();
break;
case default:
    HandleUnrecognized();
break;

}

This one doesn't work:
Operator '|' cannot be applied to operands of type 'string' and 'string'

Any other suggestions?
Thanks,

Why not encapsulate it by creating a bool property called IsInteger and do
the comparison in there. At least your clients would see tidier code.

public bool IsInteger()
{
    get { return ( myDataType == "int" || myDataType == "smallint" ); }
}

Moore, Dot Net Guruhew
Are there other possibilities of words that would cause a problem that you wouldn't want such as longint? If not, I would think you could compare it to the last 3 characters of the string to see if it is == "int" but if it could be longint or some other ....int, then this approach wouldn't work. :(

>if( myDataType == ("int" || "smallint") )

You can't apply Boolean operators to strings - a string isn't true or false,
it just is. It looks like what you're really trying to do is see if
myDataType is in the set {"int","smallint"}. You could put "int" and
"smallint" into a set-based class - most set based classes have a contains()
method. But I think that might be overkill if there are only two values -
if( myDataType == "int" || myDataType == "smallint" ) is probably the way to
go.
