将字符串文字与DirectoryInfo枚举连接起来，并添加引号. [英] Concatenate string literals with DirectoryInfo enumeration and adding quotation marks.

问题描述

这似乎是个晦涩的问题，但是在这里:

This seems like such an obscure question, but here it goes:

当在文件路径周围添加引号时，是否有一种方法将String Literal与DirectoryInfo枚举(包含文件路径)连接起来?此外，在将DirectoryInfo枚举转换为字符串时，如何防止反斜杠加倍?我的情况如下:

Is there a way to concatenate String Literals with a DirectoryInfo enumeration (which contains a file path) while adding quotations around the file path? Further, how can I prevent backslashes from being doubled when converting a DirectoryInfo enumeration to a string? My situation is as follows:

DirectoryInfo filePathDirectory = new DirectoryInfo(filePath);
Process a = new Process();

a.StartInfo.FileName = "C:\\Windows\\system32\\lpr.exe";
a.StartInfo.Arguments = "-SServername.Domain.net -Plp " + "\"" + filePathDirectory + "\"";
a.StartInfo.UseShellExecute = false;
a.Start();
a.WaitForExit();

filePathDirectory的起始值为:

{\\ServerName\Share\Folder\Folder\FileName.xls}

我认为，一旦连接到a.StartInfo.Arguments并分配了以下值，该字符串便会转换为字符串:

Which I think is converted into a string once concatenated into a.StartInfo.Arguments which is assigned the value of:

-SServername.Domain.net -Plp \"\\\\ServerName\\Share\\Folder\\Folder\\FileName.xls\"

这很糟糕，因为路径中的反斜杠数量增加了一倍.如何确保没有反斜杠添加到路径?

This is bad because, the number of backslashes in the path doubled. How can I ensure no backslashes are added to the path?

最重要的是，为了添加引号，我使用了反斜杠转义序列.但是这个转义序列中的反斜杠被无意中添加到了我的字符串中.如何在a.StartInfo.Arguments中包含的文件路径周围添加引号?

On top of that, to add a quotation marks, I've used the backslash escape sequence; But the backslash from this escape sequence is inadvertently added to my string. How can I add quotation marks around the file path which is contained in a.StartInfo.Arguments?

P.S.我希望这是有道理的，如果需要澄清，请提出问题.

P.S. I hope this makes sense, please ask questions if you need clarification.

推荐答案

反斜杠未加倍，引号的反斜杠也不存在".您可以通过Console.WriteLine(a.StartInfo.Arguments)或MessageBox.Show(a.StartInfo.Arguments)进行验证.

The backslashes are not doubled and the backslash of the quotes also "isn't there". You can verify it by Console.WriteLine(a.StartInfo.Arguments) or MessageBox.Show(a.StartInfo.Arguments).

您所看到的-在我假设的调试器中-是带有转义字符 not 的字符串表示形式-就像您需要在IDE中输入它一样.

What you are seeing - in the debugger I assume - is the representation of the string with the escape characters not translated - just as you would need to enter it in the IDE.

示例:

string s = "\"";

这将在调试器中显示为"\""，但在屏幕上显示为":

This will show in the debugger as "\"" but it will display on screen as ":
