<clause number="10.7.1.1" title="Hiding through nesting">
<paragraph>Name hiding through nesting can occur as a result of nesting namespaces or types within namespaces, as a result of nesting types within classes or structs, and as a result of parameter and local variable declarations. </paragraph>
<paragraph>
<example>[Example: In the example <code_example><![CDATA[
class A
{
int i = 0;
void F() {
int i = 1;
}
void G() {
i = 1;
}
}
]]></code_example>within the F method, the instance variable i is hidden by the local variable i, but within the G method, i still refers to the instance variable. end example]</example>
</paragraph>
<paragraph>When a name in an inner scope hides a name in an outer scope, it hides all overloaded occurrences of that name. <example>[Example: In the example <code_example><![CDATA[
class Outer
{
static void F(int i) {}
static void F(string s) {}
class Inner
{
void G() {
F(1); // Invokes Outer.Inner.F
F("Hello"); // Error
}
static void F(long l) {}
}
}
]]></code_example>the call F(1) invokes the F declared in Inner because all outer occurrences of F are hidden by the inner declaration. For the same reason, the call F(&quot;Hello&quot;) results in a compile-time error. end example]</example> </paragraph>
