Question by Marijn van Vliet · Nov 18, 2010 at 12:22 PM · javascriptstringscomparison

Comparing .NET Strings and JavaScript Strings

Question in short:
How do I compare a .NET String object with a JavaScript string or better yet: convert the one into the other?

Background:
I have a C# class handling tcp/ip socket connections. You can register functions with the class that handle incoming messages like so:

comm = new IPCommunicator("127.0.0.1", 9000); comm.addHandler(OnMessageReceived);

function OnMessageReceived(message) { // Handle message }

Now, the parameter passed to OnMessageReceived by the IPCommunicator class will be of a .NET String type. Inside the handler function I wish to be able to write code like:

if(message == 'some command') {
   DoSomeCommand();
}

But of course .NET Strings and javascript strings can't be compared like that.

Javascript's String is the exact same one as string used in c# (Both are System.String)

Your snippet code was wrong is all, change it to this:

if(message == "some command") {
   DoSomeCommand();
}

and it should work fine.

All of .NET's string functions are usable with Javascript
