文件名有两个反斜杠C＃ [英] File name has two backslashes C#

问题描述

对此可能有一个简单的答案，但是当我在我的fileName中添加 DateTime.Now.ToString（）时，我每增加一个\就额外增加一个\因此， C：\Temp 变为 C：\\Temp ，导致文件无法保存。

There is probably an easy answer for this, but when I added DateTime.Now.ToString() to my fileName it adds an extra \ for every \ I have so C:\Temp becomes C:\\Temp which causes the file not to save.

这是有问题的代码

String fileName = @"C:\Temp\data_" + DateTime.Now.ToString() + ".txt";

例如，输出可能是 C：\\Temp\ \data_12 / 04/2012 20：08：40.txt

应为 C：\Temp \data_12 / 04/2012 20：08：40.txt

推荐答案

不是，那个字符串 really 中包含单个反斜杠。将其打印到控制台上，您会看到它。

Nope, that string really has single backslashes in. Print it out to the console and you'll see that.

如果您在 debugger ，您会看到反斜杠转义了-但是字符串本身只有一个反斜杠。这咬了很多人：（

If you look at it in the debugger, you'll see the backslashes escaped - but the string itself has single backslashes. This bites lots of people :(
