Question

任何人都可以帮我解决下面的代码吗？我在第4行得到了“论据例外”。 InnerException是Nothing。

Using btm As Bitmap = Image.FromStream(importFile.InputStream)
    Using newImage As Bitmap = ResizeImage(btm, StoringSize)
        Dim stream As New MemoryStream
        newImage.Save(stream, Imaging.ImageFormat.Bmp) 'Argument exception occurred. Parameter is not valid
        StoringFilesHelper.SaveFile(fileName, stream, folderType)
    End Using
End Using

此代码无任何例外：

Using btm As Bitmap = Image.FromStream(importFile.InputStream)
    Using newImage As Bitmap = ResizeImage(btm, StoringSize)
        'Dim stream As New MemoryStream
        'newImage.Save(stream, Imaging.ImageFormat.Jpeg)
        'StoringFilesHelper.SaveFile(fileName, Stream, folderType)

        Dim filePath As String = StoringFilesHelper.GetLocalPath(fileName, folderType)
        newImage.Save(filePath)
    End Using
End Using

最后，我明白了。 http://blog.lavablast.com/post/2007/11/29/The-Mysterious-Parameter-Is-Not-Valid-Exception.aspx 图像以ResizeImage方法处理。

尝试不使用此行运行代码：

StoringFilesHelper.SaveFile(fileName, stream, folderType)

将位图保存到流时导致“参数异常”的原因是什么？
