VB.NET中如何为类的数组属性执行对象初始化操作？

错误根因 #

Ins类的SizeCodeList属性是SizeCode()数组类型，你原有代码直接传入了单个SizeCode对象，类型不匹配导致报错。

正确实现代码 #

创建数组时用New SizeCode() {}语法把所有SizeCode实例包裹在大括号内即可：

单元素数组示例 #

Dim myVar = New Ins _
  With {.Item = New Item1 With {.Code = "I"},
        .SizeCodeList = New SizeCode() {New SizeCode With {.SizeCode1 = "S", .SizeCodeDescription = "Description"}}}

多元素数组示例 #

如果需要存入多个尺寸编码，直接在大括号内用逗号分隔多个SizeCode实例即可：

Dim myVar = New Ins _
  With {.Item = New Item1 With {.Code = "I"},
        .SizeCodeList = New SizeCode() {
            New SizeCode With {.SizeCode1 = "S", .SizeCodeDescription = "小码"},
            New SizeCode With {.SizeCode1 = "M", .SizeCodeDescription = "中码"},
            New SizeCode With {.SizeCode1 = "L", .SizeCodeDescription = "大码"}
        }}
