Solution 1

You have to put something in between two square brackets e.g. [0] [i]

Pick a number 0 to 9 which corresponds to the field you want.

Solution 2

What I can see from your example is that objRec.System is an IList or Array type, so you should specify the index of the item your want the cLLI Property from.
For example:

C#

label.text = objRec.System[0].cLLI ; // Gets the first item in the list. If there are no items throws a NullReferenceException.

hi,

sorry...cLLI is a field in that method, i have 9 more fields, then how can i write for others (lable2,lable3)..

Thx

Thanks

label1.Text = objRect.System[0].cLLI;
label2.Text = objRect.System[1].cLLI;
label3.Text = objRect.System[2].cLLI;
...
Or did you mean this?
label1.Text = objRect.System[0].cLLI;
label2.Text = objRect.System[0].OtherField;
label3.Text = objRect.System[0].OtherOtherFields;

Or maybe you could do it in a for or foreach loop. Depends on your situation.

I voted 5, but OP is lost -- hard to help though. Your comment in response to first follow-up question above is good, but OP's confusion is to big. I would advise OP to start learning programming from the very first steps.

Thanks SA. I'm afraid you're right. OP seems to be confusing fields, properties, classes and methods... A bad sign indeed :)
