    <p><strong>QUESTION</strong></p> <p>Please take a look to the code first.</p> <p>Here is my custom class:</p> <pre><code>public class float2D { public float X { get; private set; } public float Y { get; private set; } public float2D(float x, float y) { this.X = x; this.Y = y; } public static explicit operator Point(float2D x) { return new Point((int)x.X, (int)x.Y); } ... } </code></pre> <p>And here is the test code I wrote:</p> <pre><code> private void TEST() { float2D V = new float2D(1, 1); Point P = Point.Empty; P = (Point)V; // Works P = (Point)(V as object); // Specified cast is not valid. } </code></pre> <p>As you can see it failed to convert the value when value type is not known. I believe this happens because it search in Object class for operand not in real type. How can I solve this problem?</p> <p>I have a code where EVERYTHING is object and it must take care of these conversations.</p> <p>Please tell me if you have any Idea.</p> <hr> <p><strong>AVOIDING DYNAMIC</strong></p> <p>Ok let change the sample in the way you can see what I exactly want to do and what is my situation.</p> <p>Here is the class I have:</p> <pre><code> class TEST { dynamic OBJECT; public void STORE&lt;T&gt;(ref T V) { this.OBJECT = V; } public T CONVERT&lt;T&gt;() { return (T)this.OBJECT; } } </code></pre> <p>And here is the test code:</p> <pre><code> float2D V = new float2D(1, 1); TEST t = new TEST(); t.STORE(ref V); Point P = t.CONVERT&lt;Point&gt;(); </code></pre> <p>Is there way I can drop dynamic from above class and keep it working? I really want to avoid .Net4/4.5</p>

    3. CO@daveL - I'd assume its because the [constructor for Point](http://msdn.microsoft.com/en-us/library/s9b80s6c%28v=vs.110%29.aspx) takes integers.

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.
