Showing build/compile time error

[NitinSawant]

Hi,
Is it possible to validate property of a ASP.NET UserControl at compile time..

e.g. ID="1" shows an error

I have a public property called 'UploadDirectory'
I want to show error message when the directory is not present..

I wrote following code for the public property but it works as expected at runtime only

    /// <summary>
    /// Format e.g. ~/UploadDirectory/
    /// </summary>
    public string UploadDirectory
    {
        get { return _UploadDirectory; }
        set {
            if (!value.EndsWith("/"))
            {
                _UploadDirectory = value + "/";
            }
            else
            {
                _UploadDirectory = value;
            }
            if(!Directory.Exists(Server.MapPath(UploadDirectory)))
            {
                FileNotFoundException ex =new FileNotFoundException("The directory doesn't exists,\nPlease create the directory: " + UploadDirectory);
                ex.Source=this.Request.Url.AbsolutePath;
                throw ex;
            }
        }
    }
 

Please help

warm regards,
Nitin

You certainly can't..

Although you can check it while debug

but then how it shows error for the other properties
e.g. ID="1"

@NitinSawant
Where's the code... where you used ID property..

[NitinSawant]

Here's the code of usercontrol in page:

<uc1:UserCtrl ID="MyCtrl1" UploadDirectory="~/TestDirectory/" runat="server" />

now I need to show error[at compile time] when the directory "TestDirectory" is not present..

Have you tried using preprocessor directives?

For example:

#If ID = 1
 'do code here
#End If
