The <code>Type<\/code> class has two properties: <code>IsPublic<\/code> and <code>IsNonPublic<\/code>. You can use them to determine the access mode of your types:<\/p>\n<pre><code>public class Public\n{ }\ninternal class Program\n{\n    private class Private\n    {\n\n    }\n    [STAThread]\n    private static void Main(string[] args)\n    {\n        Private pr = new Private();\n        Console.WriteLine(pr.GetType().IsPublic); \/\/ false\n        Public pu = new Public();\n        Console.WriteLine(pu.GetType().IsPublic); \/\/ true\n\n    }\n\n}\n<\/code><\/pre>\n<p>But there are some pitfalls. As already mentioned in the comments, you will hardly be able to create an instance of a <code>private<\/code> class, unless it was declared inside the same class as the method that is trying to determine the access modifier.<\/p>\n<p>Furthermore, these properties (<code>IsPublic<\/code>) determines the <em>effective<\/em> access to the type. So if you declare a public class inside an internal class, <code>IsPublic<\/code> will return <code>false<\/code> again:<\/p>\n<pre><code>internal class Program\n{\n    public class Public\n    { }\n\n    [STAThread]\n    private static void Main(string[] args)\n    {\n        Public pu = new Public();\n        Console.WriteLine(pu.GetType().IsPublic); \/\/ false, because Program is internal\n    }\n}\n<\/code><\/pre>\n<p>Depending on what you are trying to achieve, there may be more interesting solutions using reflection.
