Examples

The following example demonstrates how to use the InvalidApplicationPathCharacters method to validate application paths.

using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.Web.Administration;
using Microsoft.Web.Management;

namespace AdministrationSnippets
{
    public class AdministrationApplicationCollectionInvalidApplicationPathCharacters
    {
        // Determines if the paths provided are valid application paths
        public void ValidateApplicationPathCharacters()
        {
            string[] paths = { "\\Blog", "/Blog", "/Blog?", ":/Blog" };
            foreach (string path in paths)
            {
                Console.WriteLine("{0} is {1}", path, 
                    IsValidApplicationPath(path) ? "valid" : "invalid");
            }
        }

        // Validates applicationpath characters before adding an application
        public bool IsValidApplicationPath(string path)
        {
            return (path.IndexOfAny(
                ApplicationCollection.InvalidApplicationPathCharacters()) == -1);
        }
    }
}

Remarks

In a Windows operating system that is running the common language runtime (CLR), this method will return the following characters: \?;:@&=+$,|"<>*

"*" is an invalid file system character. You cannot use the remaining characters in managed-code location tags. The "/" character is acceptable for a virtual directory.
