Context (computing)

<h2 id="context-types">Context types</h2>
<p>In some computer languages like C#, there is also the concept of <i>safe</i>/<i>secure context</i>. For instance, if an <a href="/facts/Array_data_type/gHJJ3XPw">array</a> is needed inside a <a href="/facts/Struct_(C_programming_language)/mmhEWucA">structure</a>, it can be added to it since version 2.0, but only in an unsafe/unsecure context.<a class="footnote-ref" id="fnref:1" href="#fn:1"><sup>1</sup></a> Here is an example code:
</p>
struct ParameterRepresentation
{
    char target;
    char taskStart;
    char taskType;
    fixed byte traceValues[m_MAX_BYTES];
};

<p>The <a href="https://en.wikibooks.org/wiki/C_Sharp_Programming/Keywords/fixed">fixed</a> keyword prevents the <a href="/facts/Garbage_collector_(computing)/j2vlIu7g">garbage collector</a> from relocating this variable. The access to an array is like in C++, i.e. using pointer arithmetic, where individual elements of the array can be accessed over its indices.
