Solution 1

objRec.System[] is not a valid object reference; add an index value to tell the compiler which element you are referring to.

Solution 2

C#

if(objRec.System[]="" )
{

}

if you are looking for a value with in the array you should have an array index, or else if you would like to check if the array is empty or not do the following.

C#

if(objRec.System.Count == 0 )
{

}

Hope it helps!!

What's "not working". You already got answers, now it looks like you need to learn the very basics of programming from scratch as you apparently did not get it. Do it until it's too late.

Vote 4. It's correct, but don't use "", use string.Empty.
