文件名有两个反斜杠 C#

File name has two backslashes C#(文件名有两个反斜杠 C#)

问题描述

这可能有一个简单的答案，但是当我将 DateTime.Now.ToString() 添加到我的文件名时，它会为每个 添加一个额外的 我有所以 C:Temp 变为 C:\Temp 导致文件不保存.

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:Tempdata_" + DateTime.Now.ToString() + ".txt";

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

应该是C:Tempdata_12/04/2012 20:08:40.txt

推荐答案

不，那个字符串真的里面有一个反斜杠.把它打印到控制台，你会看到的.

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

如果您在 调试器 中查看它，您会看到反斜杠已转义 - 但字符串本身具有单个反斜杠.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 :(
