Xojo 类型不匹配错误。预期的字符串，但得到布尔值

Question

（我今天开始学习数组。）编辑：我意识到 = 显然是导致错误的原因，因为它被视为“比较是否相等”与“赋值”。

我没有看到引用行中的哪一部分导致了错误：

'Option 1
Var citylistDE(5) as string

citylistDE(0) ="Genf"
citylistDE(1)="Lausanne"
citylistDE(2)="Bern"
citylistDE(3)="Basel"
citylistDE(4)="Zürich"
citylistDE(5)="St.Gallen"


dim countDe as Integer = citylistDE.LastRowIndex
for i as integer = 0 to countDe
  de.Value = de.Value = citylistDE(i) + EndOfLine '<===  THIS LINE ?
next

'Option2
var citylistFR() as string =  array("Genève", "Lausanne", "Berne", "Bale", "Zurich", "Sant-Gall")

dim countFR as integer = citylistFR.LastRowIndex
for i as integer = 0 to countFR
  fr.Value = fr.Value + citylistFR(i) + EndOFLine
next

Answer 1

我发现了错误。它是 de.Value 和 citylistDE 之间的 =。我把它从 = 改成 +.

de.Value = de.Value = citylistDE(i) + EndOfLine
next
to
de.Value = de.Value + citylistDE(i) + EndOfLine
next
