ps. &nbsp;You will need to test before the second response because arrDataObject could be null - which results in you program crashing if you try to access it when it is null.

<div>
try like:<br />
<br />
 How do I declare arrDataObject outside the if statement<br />
so it is in scope for test 2?<br />
<br />
  string [] arrDataObject;<br />
<br />
            if(request.QueryStrin<wbr />g[&quot;dataobj<wbr />ects&quot;] != null)<br />
            {<br />
                  arrDataObject = request.QueryString[&quot;datao<wbr />bjects&quot;].S<wbr />plit(new Char [] {'~'}, StringSplitOptions.RemoveE<wbr />mptyEntrie<wbr />s);<br />
                  response.Write(<wbr />&quot;test 1&quot; + arrDataObject[0] );<br />
            }<br />
//try check the arrDataObject.length when necessary else you may get error below<br />
response.Write(&quot;test 2&quot; + arrDataObject[0] );

sorry, ignore my last comment as it may not work.

The code below succeeds test 1, fails test 2.  How do I declare arrDataObject outside the if statement
so it is in scope for test 2?

		if(request.QueryString["dataobjects"] != null)
		{
			string [] arrDataObject = request.QueryString["dataobjects"].Split(new Char [] {'~'}, StringSplitOptions.RemoveEmptyEntries);
			response.Write("test 1" + arrDataObject[0] );
		}

response.Write("test 2" + arrDataObject[0] );

C# string array scope

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).
