附加信息：无法将索引0处的字节[FF]从指定代码页转换为Unicode

Question

我做了一个小应用程序来序列化和反序列化xml中的图像。我尝试做的是序列化，然后将其反序列化为位图类型并返回它。然后我想把这个图像放到一个列表框中，所以我以编程方式创建了一个pictureBox但是当我尝试将内存流转换为Bitmap时，我得到以下错误public JsonResult GenericName_Bind(string ProductID) { PrescriptionBind generic = new PrescriptionBind(); DataSet ds = generic.Get_GenericName(ProductID); List<SelectListItem> statelist = new List<SelectListItem>(); foreach (DataRow dr in ds.Tables[0].Rows) { statelist.Add(new SelectListItem { Text = dr["GenericName"].ToString(), Value = dr["GenericID"].ToString() }); } return Json(statelist, JsonRequestBehavior.AllowGet); } #endregion public DataSet Get_GenericName(string ProductID) { SqlCommand com = new SqlCommand("Select * from ProductMaster where ProductID=@ProductID", product); com.Parameters.AddWithValue("@ProductID", ProductID); SqlDataAdapter da = new SqlDataAdapter(com); DataSet ds = new DataSet(); da.Fill(ds); return ds; } ，这是一个Additional information: Unable to translate bytes [FF] at index 0 from specified code page to Unicode。我不确定我应该给XMLSerializedr类DescoderFallbackException什么，但我假设它是Bitmap。

我的代码如下

调用Serializer和Deserializer方法并将返回的图像放入picturebox的代码

GetType

序列化方法

 Dim mem As MemoryStream

            Serialize()
            Dim pic As Bitmap = Deserialize(mem)
            ListBoxTemplates.Items.Clear()
            Dim selectedCatID = AppSettings.PowerPoint.TemplateCategories.SingleOrDefault(Function(t) t.Name = ComboBoxNewLevel1.Text).ID
            Dim selectedCat2ID = AppSettings.PowerPoint.TemplateCategories.SingleOrDefault(Function(t) t.Name = ComboBoxNewLevel2.Text).ID


            Dim level3Cat = From Temp In AppSettings.PowerPoint.PSLTemplates
                            Join cat In AppSettings.PowerPoint.TemplateCategories On Temp.CategoryLevel1ID Equals cat.ID
                            Where Temp.CategoryLevel1ID = selectedCatID And selectedCat2ID = Temp.CategoryLevel2ID
                            Select Temp.Name

            For Each t In level3Cat

                Dim pb As PictureBox = New PictureBox()

                pb.Location = Location()

                pb.Name = ""
                pb.BackgroundImage = pic


                ListBoxTemplates.Items.Add(pb)
            Next

反序列化方法（问题出在哪里）

Public Sub Serialize()

    Dim corolla As New Bitmap("C:\xmltext.png", True)


    Dim ms As New MemoryStream()

    corolla.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg)

    Dim sw As New StringWriter()

    Dim xw As New XmlTextWriter(sw)

    xw.Formatting = Formatting.Indented

    Dim ser As New XmlSerializer(ms.GetBuffer().[GetType]())

    ser.Serialize(xw, ms.GetBuffer())

    Debug.WriteLine("Serialized Content::")

    Dim sSerializedContent As String = sw.GetStringBuilder().ToString()

    Debug.WriteLine(sSerializedContent)
    mem = ms
    xw.Close()

End Sub
