Question

我有文件移动操作，文件夹路径有特殊字符，如[，（，〜）以及一些具有这些特殊字符的文件名。我从.csv文件中读取文件路径和名称。现在我会就像那些要移动的文件一样，当我尝试移动c＃时，我在路径错误中得到非法字符。如何通过该错误并移动文件？

while ((line = reader.ReadLine()) != null)
{
    char[] delimiters = new char[] { ',' };
    parts= line.Split(delimiters);
    if (parts.Length > 0)
    {
        SourceFilePathCSV = parts[0];
        SourceFileNameCSV = parts[1];
        filesize = parts[2];

        totalSourceFilePath = Path.Combine(SourceFilePathCSV ,SourceFileNameCSV);
        strDestinationDynamicPath = SourceFilePathCSV.Replace("\\\server\folder\\", " ").TrimEnd();
        strConstructedDestinationfullpath = Path.Combine(strDestinationStaticPath, strDestinationDynamicPath);
        if (!string.IsNullOrEmpty(strConstructedDestinationfullpath)) 
        {
            if (!Directory.Exists(strDestinationDynamicPath))
            {
                Directory.CreateDirectory(strConstructedDestinationfullpath);
                try
                {
                    if (File.Exists(totalSourceFilePath))
                    {
                        strtotaldestinationpath = Path.Combine(strConstructedDestinationfullpath, SourceFileNameCSV);
                        File.Move(totalSourceFilePath, strtotaldestinationpath);
                        string changed = Path.ChangeExtension(totalSourceFilePath, ".txt");
                        File.WriteAllText(changed, strTextInsidefile);
                        logMessage = "SourceFile = " + totalSourceFilePath + " DestinationFile = " + strConstructedDestinationfullpath + "  " + DateTime.Now.ToString() + "   " + loggeduserid.ToString() + " Input file = " + inputfile + "  " + "  Moved + " + "filesize = " + filesize;
                        WriteLog(logMessage);
                        filecountMoved = filecountMoved + 1;

                    }//file.exists(totalsource)
                    else
                    {
                        filecountnotmoved = filecountnotmoved + 1;
                        logMessage = "SourceFile = " + totalSourceFilePath + " DestinationFile = " + strConstructedDestinationfullpath + "  " + DateTime.Now.ToString() + "   " + loggeduserid.ToString() + " Input file = " + inputfile + "  " + "Not Moved " + "filesize = " + filesize;
                        WriteLog(logMessage);
                    }
                }
                catch (Exception ex)
                {
                    string strlogmessageex = ex.Message.ToString();
                    WriteLog(strlogmessageex);
                    return;
                }
                }//if directory not exists

        }//string or null
    }//parts.length
    filecount = filecount + 1;
}//while

您可以使用从Path.GetInvalidFileNameChars

返回的集合以编程方式从字符串中删除无效字符

但是，如果文件确实存在，那么您必须引入无效字符。除非它是复制/粘贴错误，否则可能就是这一行：

strDestinationDynamicPath = SourceFilePathCSV.Replace("\\\server\folder\\", " ").TrimEnd();

一开始你有三个斜线。 “\\”是一个字符，“\ s”是另一个字符。但这可能是复制/粘贴错误。

但是你要用空格替换它，这是文件或文件夹的第一个字符的无效字符。 TrimEnd仅删除末尾的空格。

如果不是这样，那么调试并查看strConstructedDestinationfullpath的值并寻找奇怪的东西。

由于特殊字符，文件移动操作失败
