C# 二进制格式化程序返回调用者并取消form.close

我想用二进制格式化程序序列化结构数组，以便通过网络发送，或者在这种情况下将其保存到文件中。
它已订阅表单。我的表单的关闭事件

void writeHistoryToFile(object sender, CancelEventArgs e)
{
    ListView.ListViewItemCollection coll = historyListView.Items;
    int count = coll.Count;
    if(count == 0)
        return;
    BinaryFormatter bf = new BinaryFormatter();
    MemoryStream memStr = new MemoryStream();
    searchResult[] container = new MainForm.searchResult[count];
    for(int i = 0; i < count; i++)
    {
        searchResult tagged = (searchResult)coll[i].Tag;
        container[i] = tagged;
    }
    byte[] bytesToWrite;
    bf.Serialize(memStr, container);   //HERE
    bytesToWrite = memStr.ToArray();   //BREAKPOINT

    List<FileInfo> hisFls = historyFiles;
    if(hisFls.Count != 0)
    {
        foreach(FileInfo element in hisFls)
        {
            element.Delete();
        }
    }

    FileInfo serFile = getTempFile(".avsh");
    using(FileStream writeStream = serFile.OpenWrite())
    {
        writeStream.Write(bytesToWrite, 0, bytesToWrite.Length);
        writeStream.Flush();
    }
}

“回答”以结束此问题： 尝试向代码中添加Try..Catch，并检查发生的错误。

然后使结构可序列化。；）

尝试将Try..Catch添加到函数中（或仅在序列化前后）。你得到了什么异常？@AlexS完成了，它帮助了你。@HansPassant

它吞下了异常

？！？？！什么。。？这可能需要我一段时间，因为我确信这是格式化程序本身，而不是我现在发现的结构。很高兴我能帮忙：）你怎么知道的？O:-）
