c# - 程序集“Microsoft.Office.Interop.Excel 中的 Microsoft.Office.Interop.Excel.WorkbookClass”未标记为可序列化

Question

序列化异常:程序集“Microsoft.Office.Interop.Excel，Version=11.0.0.0，Culture=neutral，PublicKeyToken=71e9bce111e9429c”中的类型“Microsoft.Office.Interop.Excel.WorkbookClass”未标记为可序列化。

我遇到了上面的异常..这是代码

unsafe public void Save(IStream stream, bool clearDirty, Excel.Workbook xlbook)
{
    try
    {
        //if (stream == null)
        //{
        //    return;
        //}
        //object data = xlbook;
        if (xlbook == null)
        {
            return;
        }
        // convert data to byteArray   


        MemoryStream memoryStream = new MemoryStream();
        BinaryFormatter binaryFormatter = new BinaryFormatter();           

       //below line im getting the Exception
        **binaryFormatter.Serialize(memoryStream, xlbook);**            
        byte[] bytes = memoryStream.ToArray();
        memoryStream.Close();
        //get memory pointer
        int cb;
        int* pcb = &cb;
        //save data
        byte[] arrayLen = BitConverter.GetBytes(bytes.Length);
        stream.Write(arrayLen, arrayLen.Length, new IntPtr(pcb));
        stream.Write(bytes, bytes.Length, new IntPtr(pcb));
        //currentDomain.AssemblyResolve -= new ResolveEventHandler(currentDomain_AssemblyResolve);
    }
    catch
    {

    }
}

不能使用序列化保存 Excel 工作簿。您必须使用其 Save 方法保存工作簿。

您说您将类标记为可序列化，但您一定标记错了类。需要标记为可序列化的类是 WorkbookClass，您无法控制该类。
