这里存在什么例外。 NET Framework在试图撰写档案时,但磁盘是完整的吗?

视窗缓冲文档是否书写?

最佳回答

您将获得国际交易日志的一个例外:

System.IO.IOException: There is not enough space on the disk.
at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)

<代码>System.IO 图书馆处理阅读和写作的实际任务,在管理代码中盘点和包装,因此,你没有利用这些例外情况处理。

这也是值得尝试的(其中之一是在任何地方带走的小型金字塔),以了解你们的法典发生了什么——这通常是发现这种事情的最佳方式。

问题回答

你们将获得一个综合研究。 但是,问题是,IOException范围很广,而不仅仅是整个磁盘。 我也建议检查人力资源部门,以准确筛选出这个案件。

                catch (IOException ioEx)
                {
                    // Is it  DISK_FULL ?
                    uint unsignedResult = (uint)ioEx.HResult;
                    if (unsignedResult.IsOneOf(0x80000027, 0x80000070, 0x80070027, 0x80070070))
                    {
                        // Remove the partial file
                        try
                        {
                            File.Delete(pathName);
                        }
                        catch { }
                        // do your special stuff here
                    }
                    else
                        throw;
                }

请注意,来自8000个地区的Win32号错误代码在807个区域中得到反映,因此在检查中几乎出现重复。

在你未能看到这是否提供了更详细的资料之后,你可以检查Win 32。

     Win32Exception ex = new Win32Exception();
     string low_level_error = ex.Message;

如何写上光盘? FileStream:

"Be sure to call the Dispose method on all FileStream objects, especially in environments with limited disk space. Performing IO operations can raise an exception if there is no disk space available and the Dispose method is not called before the FileStream is finalized."
