Simple code - convert from VB.net to c#.net (web dev)

[Gary]

Hello,

Anyone know how to do the following in c# - using inline codeblocks?

<% If Request.Form("Name") = "Gary" Then %>

<asp:RequiredFieldValidator ID="GarysValidation" ErrorMessage="Gary, you
have chosen the wrong option<BR>" ControlToValidate="Name" Display="Dynamic"
runat="server"></asp:RequiredFieldValidator>

<% End If %>

Thanks for any help,

Regards,

Gary.

There's many free online C#/VB.NET code converters you can use to do that.

Here's a few, in no particular order.
Check them out...and see which one you like best.

(via Instant C#)
<%
if (Request.Form["Name"] == "Gary")
{
%>

<asp:RequiredFieldValidator ID="GarysValidation" ErrorMessage="Gary, you
have chosen the wrong option<BR>" ControlToValidate="Name" Display="Dynamic"
runat="server"></asp:RequiredFieldValidator>

<%
}
%>

The on-line converters won't convert in-line asp.net code Juan. (see my
other reply for the conversion).

Maybe that should be a tip not to use ASP syntax in ASP.NET.
Would changing the control's visibility depending on the selected option be better ?

Absolutely!

Could you elaborate? You spotted I am a classic ASP coder, finding the
transition to .NET a challenge.

I do have a code behind file in place, and I am slowly reading about Life
Cycle etc, but at this moment I am unsure how best to approach this
particular task.

Maybe adding some server code would help...

<script language = "VB" runat="server">

Sub Get_Input (Src As Object, Args As EventArgs)
Output.Text = "You entered '" & Name.Text & "'"
End Sub

</script>

<form Runat="Server">

<asp:TextBox id="Name" Runat="Server"/>

<asp:Button Text="Submit" OnClick="Get_Input" Runat="Server"/>

<asp:RequiredFieldValidator Runat="Server"
ID="GarysValidation"
ControlToValidate="Name"
ErrorMessage="Gary, you need to enter a value."
Display="Dynamic"
SetFocusOnError="True"/>

<asp:Label id="Output" Runat="Server"/>

</form>

I'm assuming that what you are aiming for is not having an empty textbox or,
if there is one, that the user can be informed without disruption.

Is that what you are aiming for ?

The above code will display the message "Gary, you need to enter a value."
if the textbox is empty, or will display whatever the user wrote into the Name textbox.

I would like to ask that, if i have a VB.net file, is there any free
tools for me to convert it into C#.net?

Thx a lot!!!
