Is there a simple way I can change the space to an underscore?

If you want to do it in place:
如果你想就地做：
abc = abc.Replace(" ", "_");
Although do realize a newstringinstance will be created; it's not actually done in the same memory location - Stringis an immutable type.
尽管确实意识到将创建一个新string实例；它实际上不是在同一个内存位置完成的 -String是一种不可变的类型。

Using String.Replace(char,char)instead of String.Replace(string, string)should be much faster. i.e.
使用String.Replace(char,char)而不是String.Replace(string, string)应该快得多。IE
abc = abc.Replace(' ', '_');

simply add .Replace()function at the end of the string.
只需.Replace()在字符串末尾添加函数即可。
abc = abc.Replace(' ', '_');
