推荐答案

您没有指出抛出此异常的行，但它可以是您为数组编制索引的任何位置： 名称[0] ，名称[1] 和 result.Properties [propertyName] [0 ] 。如果存在第0个或第1个元素，则永远不会检查。你需要检查一个数组至少有一个或两个元素。

另外，你需要检查元素 result.Properties [propertyName] 存在。

You did not indicate the line where you have this exception thrown, but it can be any place where you index the arrays: Name[0], Name[1] and result.Properties[propertyName][0]. You never check up if the 0-th or 1-st element exists. You need to check up of an array has at least one or two elements.
Also, you need to check up that the element result.Properties[propertyName] exists.
