我从本地服务器复制一个.txt的时候有问题。它抛出异常：

文件名，目录名或卷标语法不正确。

我想这可能是一些与路径格式，所以我试图通过向服务器路径的@：

@ Configuration.Manager [路径] | @\\ SERVERPATH \ SharedFolder

我也试着用这种格式：\\ SERVERPATH \ SharedFolder ...他们没有工作

顺便说其不是接入问题，因为我一直试图做的运行命令提示符一样的东西从C＃：

  System.Diagnostics.Process.Start（cmd.exe的，/ C复制PATH1，PATH2）; //这个工作和复制的文件。
 

我会很感激，如果有人能够给我的可能是什么问题就在这里了线索。做什么至少有一个建议。

在此先感谢和抱歉我的英文不好！

编辑：

这是的code应该工作的一部分：

 字符串路径prevDay =D：\ AuditFiles \ enc_+ svr.Name +_counts+ day.AddDays（-1）的ToString（DD-MM -YY）+名.txt;

如果（File.Exists（路径prevDay））
{
    File.Copy（路径prevDay，@ ConfigurationManager.AppSettings [MAIL_SERVER_PATH]）;
}
 

解决方案

您需要逃脱反斜杠，并指示文件在File.Copy（路径prevDay，ConfigurationManager中的名称。的AppSettings [MAIL_SERVER_PATH]）;

更改此：

 字符串路径prevDay =D：\ AuditFiles \ enc_+ svr.Name +_counts+ day.AddDays（-1）的ToString（DD-MM -YY）+名.txt;
 

这样：

 字符串路径prevDay =D：\\ AuditFiles \\ enc_+ svr.Name +_counts+ day.AddDays（-1）的ToString（DD -MM-YY）+名.txt;
 

您也可以使用单斜杠（/），而不是像这样的：

 字符串路径prevDay =D：/ AuditFiles / enc_+ svr.Name +_counts+ day.AddDays（-1）的ToString（DD-MM -YY）+名.txt;
 

I'm having problems when copying a .txt from a local server ("D:\AuditFiles") to a shared folder in another server ("\\PrintServer\SharedFolder"). It throws the exception:

"The filename, directory name, or volume label syntax is incorrect."

I thought it could be something with the path format, so I tried by adding to the server path an @:

@Configuration.Manager["Path"] | @"\\ServerPath\SharedFolder"

I've also tried with this format: \\ServerPath\SharedFolder... None of them worked.

By the way its not an access problem, cause i've tried to do the same thing running a command prompt from within c#:

System.Diagnostics.Process.Start("cmd.exe", "/C COPY PATH1, PATH2"); //This worked and copied the file.

I'd be greatful if someone could give me a clue of what could be the problem here. At least an advice of what to do.

Thanks in advance and sorry me bad english!

Edit:

This is the part of the code that should work:

string pathPrevDay = "D:\AuditFiles\enc_" + svr.Name + "_counts" + day.AddDays(-1).ToString("dd-MM-yy") + ".txt";

if(File.Exists(pathPrevDay))
{
    File.Copy(pathPrevDay, @ConfigurationManager.AppSettings["MAIL_SERVER_PATH"]);
}

You need to escape the backslashes and indicate the name of the file in File.Copy(pathPrevDay, ConfigurationManager.AppSettings["MAIL_SERVER_PATH"]);.

Change this:

string pathPrevDay = "D:\AuditFiles\enc_" + svr.Name + "_counts" + day.AddDays(-1).ToString("dd-MM-yy") + ".txt";

to this:

string pathPrevDay = "D:\\AuditFiles\\enc_" + svr.Name + "_counts" + day.AddDays(-1).ToString("dd-MM-yy") + ".txt";

You can also use single slashes (/) instead like this:

string pathPrevDay = "D:/AuditFiles/enc_" + svr.Name + "_counts" + day.AddDays(-1).ToString("dd-MM-yy") + ".txt";
