Is this a long way to compare strings ignoring the case?


if ( string.Compare(wsUri.Host, "localHost",
System.StringComparison.OrdinalIgnoreCase) == 0 )
{
// etc.
}

Well, it's easier to use

if ("localHost".Equals(wsUri.Host, StringComparison.OrdinalIgnoreCase))

(If you know that wsUri.Host is non-null, you can swap what the method
is called on for clarity.)
 
Well it's long, but just as number of characters.
A shorter version could be string.Compare(wsUri.Host, "localHost",true)==0
It still takes three parameters.

wsUri.Host.ToString().ToUpper().Equals("LOCALHOST") would be much
simpler i think

It's not guaranteed to work though, due to potential culture issues.

I ran into a problem years ago where I was trying to compare strings
in a case-insensitive way by doing the above - and we found that in
Turkey, we had a problem, because the upper case of "i" isn't "I" in
Turkey (and vice versa).

Using a case-insensitive comparison is the best way of working.

A nice shorthand overload is:

String.Compare(wsUri.Host, "localHost", true) == 0 ...
