Question

我在Windows应用程序中遇到问题。我想更新图片，但它会产生异常：
“ GDI +中发生了一般性错误”

这是我的代码：

Dim ms As New MemoryStream
PicMeter.Image.Save(ms, PicMeter.Image.RawFormat) 'here exception occurs
Dim arr As Byte() = ms.GetBuffer()
ms.Close()

Answer 1

变化

PicMeter.Image.Save(ms, PicMeter.Image.RawFormat)

到

PicMeter.Image.Save(ms, ImageFormat.RawFormat)

如果这没有帮助，是否有助于创建新图像并从中保存？正如这里建议的那样：http://www.dreamincode.net/forums/topic/49392-pictureboximage-save-error/

Dim ms As New MemoryStream
Dim bitmp As New Bitmap(PicMeter.Image)
bitmp.Save(ms, ImageFormat.RawFormat)
Dim arr As Byte() = ms.GetBuffer()
ms.Close()

winform中的GDI +发生了一般错误
