    <pre><code>if(true) { string var = "VAR"; } string var = "New VAR!"; </code></pre> <p>This will result in:</p> <blockquote> <p>Error 1 A local variable named 'var' cannot be declared in this scope because it would give a different meaning to 'var', which is already used in a 'child' scope to denote something else.</p> </blockquote> <p>Nothing earth shattering really, but isn't this just plain wrong? A fellow developer and I were wondering if the first declaration should be in a different scope, thus the second declaration cannot interfere with the first declaration. </p> <p>Why is C# unable to differentiate between the two scopes? Should the first IF scope not be completely separate from the rest of the method?</p> <p>I cannot call var from outside the if, so the error message is wrong, because the first var has no relevance in the second scope.</p>

    1. COThe actual compiler error is - A local variable named 'x' cannot be declared in this scope because it would give a different meaning to 'x', which is already used in a 'parent or current' scope to denote something else.

    3. COI presume you're using C# 2.0, since `var` is a keyword in C# 3.0.

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.
