在 User.config 文件中存储单个字符(制表符、换行符、任何字符) [英] Store a single character (tab, new line, any character) in User.config file

问题描述

我想在 User.config(或 App.config)文件中存储和保存单个字符.普通字符可以很容易地保存，但是当涉及到像 \t, \n 这样的特殊字符时，我无法存储它们，因为 VS2012 说它不是一个字符.我用 \t 的 XML 标记修改 User.config 文件，它是 	 它有效！但是，当再次保存时，它失败了.当我在代码 Properties.Settings.Default.delim = '\t' 中分配这样的 \t 字符并调用 Save 方法时，仅编程存储 \0 字符.我无法在代码中存储 XML 等效字符串，因为它是一个字符串，而不是一个字符，我正在尝试将一个字符串分配给一个字符.

I want to store and save back a single character in User.config (or App.config) file. Normal characters can be hold easily, but when it comes to special characters like \t, \n I cannot store them because VS2012 says it is not a character. I modify the User.config file with XML tags of \t which is 	 it works! However, when it comes to save it again, it fails. When I assign \t character like this in code Properties.Settings.Default.delim = '\t' and call Save method, program only stores \0 character. I cannot store XML equivalent string in code because it is a string, not a character and I'm trying to assign a string to a character.

对此有什么想法吗?

推荐答案

您可以通过转换为 int 来存储字符的十进制 ASCII 代码，然后将其转换回 char 在你的程序中.

You could store the decimal ASCII code for the character by converting to an int, and convert it back to a char in your program.

例如

char charToSave = '\t';
int code = (int)charToSave;
SaveCharToUserConfig(code);

...

int code = GetCodeFromUserConfig(); 
char savedChar = (char)code;
