Validate text expression without RegularExpressionValidator server side
Posted: February 6, 2013 Filed under: Asp.net, C# | Tags: .net, C#, IsMatch, regular expression validator, RegularExpressions.Regex, System.Text, validate text Leave a commentHi,
To validate the text expression without using regular expression validator on your code behind (i.e. on server side- .cs), use following code:
bool validText= System.Text.RegularExpressions.Regex.IsMatch(“Your Text”, “Your Expression”)
for example, I need to validate value of Email Address text box of the submission form:
bool validEmailId=System.Text.RegularExpressions.Regex.IsMatch(txt_emailid.Text,
“\\w+([-+.’]\\w+)*@\\w+([-.]\\w+)*\\.\\w+([-.]\\w+)*“);
That’s it..
Enjoy Coding 🙂
Test Connection To host / Is host reachable / PING functionality C#
Posted: February 22, 2011 Filed under: C# | Tags: .net, C#, IPStatus, is host reachable, ping functionality, PingReply, test connection to host 2 CommentsHi,
We can check the particular machine is get ping or not from using C# code.
Also, we can get the Round-triptime of packet.
Using Ping and PingReply class, we can do this.
The code is as below
Ping x = new Ping();
PingReply reply = x.Send(IPAddress.Parse("192.168.1.1")); //enter ip of the machine
if (reply.Status == IPStatus.Success) // here we check for the reply status if it is success it means the host is reachable
{
status.Text = "Available. And Round Trip Time of the packet is:"+reply.RoundtripTime.ToString();
}
else //if host is not reachable.
status.Text = "Not available";
Just 3-4 lines will solve the issue.
That’s it.
Enjoy Coding.. 🙂
