== Why is this an issue?

String representations of URIs or URLs are prone to parsing and encoding errors which can lead to vulnerabilities. The ``++System.Uri++`` class is a safe alternative and should be preferred.


This rule raises an issue when a method has a ``++string++`` return type and its name contains "Uri", "Urn", or "Url" or begins with  "uri", "urn", or "url".


=== Noncompliant code example

[source,text]
----
using System;

namespace MyLibrary
{
   public class MyClass
   {
      public string GetParentUri() // Noncompliant
      {
         return "http://www.mysite.com";
      }
   }
}

=== Compliant solution

[source,text]
----
using System;

namespace MyLibrary
{
   public class MyClass
   {

      public Uri GetParentUri() 
      {
         return new URI("http://www.mysite.com");
      }
   }
}
