If you opened this file directly from disk, your browser may be directly suppressing JavaScript functionality: certain browsers perform this suppression on local files (but not files delivered by web servers) for security reasons.

If you access the manual through the hub's Web GUI, the functionality will not be suppressed because the hub is a web server.
Alternatively, your browser may allow you to explicitly disable the security setting that suppresses functionality. See the CodeSonar FAQ for more information.

CSHARP.COMPARE.EQUALS.CN : Comparison to Class Names (C#)

Summary

Class names are compared with Equals(). This is not a reliable check for class equality, because multiple classes might have the same name.

Properties

Example

using System;
using System.Diagnostics;

namespace DocumentationExamples {
    public class BadEq {
        public static void Main(string[] args) {
            string s = "";
            object o = "";
            if (s.GetType().Name.Equals(o.GetType().Name)) // 'Comparison to Class Names (C#)' warning issued here
                // ... 
            }
        }
    }
}

Resolution

To check if two objects have the same class, use the getType() method and the == operator.
