You could try setting the Parent property of the PictureBox to the new Panel.

Using Regex in C# for ip:port format

Hi all,

I am using C#.Net 2008.

I am using following code to varify proper format (udp ip:port i.e "225.1.1.1:3000") of input string.
But it is not working properly.

System.Text.RegularExpressions.Regex regStr = new System.Text.RegularExpressions.Regex(@"\d{1,3}.\d{1,3}.\d{1,3}.\d{1,3}:\d{1,5}");

bool b;
b = regStr.IsMatch("225.1.1.1:3000"); //return true
b = regStr.IsMatch("2225.1.1.1:3000"); //return true. should return false

Anybody knows proper regular expression for ip:port format?
Can anyone give me good links for using Regex , regular expression in C#.

Thanks in advance.

Regards,
Aniket A. Salunkhe

This behavior is correct, because the regexp you wrote checks for matches contained in the input string.
If you want to match the whole string only, you must add ^ at the begin and $ at the end of your regex.

For Example: "^\d{1,3}.\d{1,3}.\d{1,3}.\d{1,3}:\d{1,5}$"

Wrong, try again.

It wasn't that wrong. I have to be honest I missed the unescaped . and thought of the other half of the problem (^,$ to match beginning and end)

You need to escape the '.' else it will match anything.

That is true, too. You must also replace all the . with \.

So, the regex is "^\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}:\d{1,5}$"
Take in mind that also the above regex is not absolutely correct. For example, it matches also 999.999.999.999:3000.

Thanks. It's working to check proper format of string.

Still I am working to check proper formt of string with correct ip address & port.

Try This :
System.Text.RegularExpressions.Regex regStr = new System.Text.RegularExpressions.Regex(@"^[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}:[0-9]{1,5}$");

Thanks!

Wrong! Same mistake as Mirko1980.

Try 123a123a123a123, your regex will match that too!

But this work's fine.
MessageBox.Show(System.Text.RegularExpressions.Regex.IsMatch("123a123a123a123", @"^[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}:[0-9]{1,5}$", System.Text.RegularExpressions.RegexOptions.ExplicitCapture).ToString());

Rather use \. than [.] . Some regex implementations might see [.] as .

I'd just try to open the port and let the framework figure it out.

Another thread came up with:

@"^[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}[:][0-9]{1,5}$"

But what if you want to constrain the octets to ONLY values from 0 to 255? And what if you really wanna go whole hog and constrain the port to 0 to 65535?

I don't know regular expressions that well, so I am curious.
