小问题：Structure中的变量如何赋初值？

[OnlyVB]

   Private Structure ExcelApp
       Public SheetMode As Boolean   '例：初值True
        Public SheetIndex As Integer  '如：初值5
    End Structure

谁知道咋赋初值呀？
用Public Shared SheetIndex As Integer=5可以，但不能修改呀！

[wind_cloud2011]

Dim ct As New ExcelApp With {.SheetMode = True, .SheetIndex = 21} Dim s As Integer s = ct.SheetIndex

[wind_cloud2011]

如果数据修改，用 cust.SheetIndex = 23这样就可

写一个构造函数。 注意，结构体允许不调用构造函数，所以如果你强制要求赋值，还是用class吧。

[无涯大者]

    Private SheetExcelApp As ExcelApp
    Private Structure ExcelApp
        Public SheetMode As Boolean   '例：初值True
        Public SheetIndex As Integer  '如：初值5
    End Structure

定义好结构体: 直接复制就行了

  SheetExcelApp.SheetIndex = True
  SheetExcelApp.SheetIndex = 5
