Do not try to build pathnames concatenating strings. Use the Path.Combinemethod

不要尝试构建连接字符串的路径名。使用Path.Combine方法

string path = Environment.GetFolderPath(Environment.SpecialFolder.MyPictures);
Console.WriteLine(Path.Combine(path, "test"));

The Path classcontains many useful static methods to handle strings that contains paths, filenames and extensions. This class is very useful to avoid many common errors and also allows to code for a better portability between operating systems ("\" on win, "/" on Linux)

在Path类包含了许多有用的静态方法来处理包含路径，文件名和扩展名字符串。此类对于避免许多常见错误非常有用，并且还允许编写代码以实现操作系统之间更好的可移植性（win 上的“\”，Linux 上的“/”）

The Path class is defined in the namespace System.IO.
You need to add using System.IO;to your code

Path 类在命名空间中定义System.IO。
您需要添加using System.IO;到您的代码

You need escape it. \tis an escape-sequence for Tabs 0x09.

你需要逃避它。 \t是 Tabs 的转义序列0x09。

path + "\\test"

path + "\\test"

or use:

或使用：

path + @"\test"

path + @"\test"

Better yet, let Path.Combinedo the dirty work for you:

更好的是，让我们Path.Combine为你做一些肮脏的工作：

Path.Combine(path, "test");

Path.Combine(path, "test");

Pathresides in the System.IOnamespace.

Path驻留在System.IO命名空间中。

There are two options:

有两种选择：

1. Use the @ symbol e.g.: path + @"\test"
2. use a double backslash e.g.: path + "\\test"

1. 使用@ 符号，例如：path + @"\test"
2. 使用双反斜杠，例如：path + "\\test"

Backslash '\'is an escape character for strings in C#. You can:

反斜杠'\'是 C# 中字符串的转义字符。你可以：

• use Path.Combine

  Path.Combine(path, "test");
  

• escape the escape character.

  Console.WriteLine(path+"\test");
  

• use the verbatim string literal.

  Console.WriteLine(path + @"\test");
  

• 用 Path.Combine

  Path.Combine(path, "test");
  

• 转义转义字符。

  Console.WriteLine(path+"\test");
  

• 使用逐字字符串文字。

  Console.WriteLine(path + @"\test");

string add;

字符串添加；

add += "\"; //or :"\" means backslash

回答by trinalbadger587

the backslash is an escape character, so use
Console.WriteLine(path+"\\test");
or
Console.WriteLine(path+@"\test");

反斜杠是一个转义字符，所以使用
Console.WriteLine(path+"\\test");
或
Console.WriteLine(path+@"\test");
