推荐答案

您必须在两个方括号之间放置一些内容，例如[0] [i]

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

从您的示例中可以看到，objRec.System是IList或数组类型，因此您应指定想要cLLI属性来自的项的索引. br/> 例如:

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:

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