我目前正在使用以下代码:
Public Sub CreateScore()
' open isolated storage, and write the savefile.
Dim fs As IsolatedStorageFileStream = Nothing
Using fs = savegameStorage.CreateFile("Score")
If fs IsNot Nothing Then
' just overwrite the existing info for this example.
Dim bytes As Byte() = System.BitConverter.GetBytes(Scorecount)
fs.Write(bytes, 0, bytes.Length)
End If
End Using
End Sub
然而,使用后的fs用蓝色加下划线,并在封闭块中给出错误变量'fs'隐藏变量。
有人知道如何解决这个问题吗?

您正在声明变量,然后在Using
块中使用相同的变量名称(尝试再次声明它)。
将其更改为:
Public Sub CreateScore()
' open isolated storage, and write the savefile.
Using fs As IsolateStorageFileStream = savegameStorage.CreateFile("Score")
If fs IsNot Nothing Then
' just overwrite the existing info for this example.
Dim bytes As Byte() = System.BitConverter.GetBytes(Scorecount)
fs.Write(bytes, 0, bytes.Length)
End If
End Using
End Sub

您不需要Dim fs...
行 - Using
声明涵盖声明。
Using
语句本身应该没问题,但是如果你想确定输入,那么将其改为:
Using fs As IsolatedStorageFileStream = savegameStorage.CreateFile("Score")
