    <p>might someone have a quick answer for me...</p> <p>in the following entirely useless code, under 'class DuplicateInterfaceClass : MyInterface1, MyInterface2'. </p> <p>Why can't I explicitly write "public string MyInterface2.P()"?<BR> yet "public string P()" and "string MyInterface2.P()" work.</p> <p>I understand that all interface methods (properties, etc.) are implicitly "public" by default, but my attempt to be explicit in the inheriting class results in an "error CS0106: The modifier 'public' is not valid for this item".</p> <pre><code>using System; interface MyInterface1 { void DuplicateMethod(); // interface property string P { get; } } interface MyInterface2 { void DuplicateMethod(); // function ambiguous with MyInterface1's property string P(); } // must implement all inherited interface methods class DuplicateInterfaceClass : MyInterface1, MyInterface2 { public void DuplicateMethod() { Console.WriteLine("DuplicateInterfaceClass.DuplicateMethod"); } // MyInterface1 property string MyInterface1.P { get { return ("DuplicateInterfaceClass.P property"); } } // MyInterface2 method // why? public string P()...and not public string MyInterface2.P()? string MyInterface2.P() { return ("DuplicateInterfaceClass.P()"); } } class InterfaceTest { static void Main() { DuplicateInterfaceClass test = new DuplicateInterfaceClass(); test.DuplicateMethod(); MyInterface1 i1 = (MyInterface1)test; Console.WriteLine(i1.P); MyInterface2 i2 = (MyInterface2)test; Console.WriteLine(i2.P()); } } </code></pre>

    1. COBy the way it's probably a duplicate with http://stackoverflow.com/questions/1253266/why-explicit-implementation-of-a-interface-can-not-be-public and http://stackoverflow.com/questions/2669031/compilation-error-the-modifier-public-is-not-valid-for-this-item-while-crea

    2. CObtw, I realize I shouldve said "implement" the interface not "inherit"

    3. COI think you are right Julien...oh and I can add "void" to 'DuplicateMethod()' because there is no ambiguity....

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
