Replacing multiple characters in a string in c# by a one liner
提问by user2629770
What I'm wondering of is whether it is possible to replace multiple characters in a string (lets say, the &, | and $ characters for example) without having to use .Replace() several times ? Currently I'm using it as
我想知道的是是否可以替换字符串中的多个字符（例如，&、| 和 $ 字符）而不必多次使用 .Replace() ？目前我将它用作
return inputData.Replace('$', ' ').Replace('|', ' ').Replace('&', ' ');
but that is just awful and I'm wondering if a similarly small, yet effective alternative is out there.
但这太糟糕了，我想知道是否有类似的小而有效的替代方案。

You can use Regex.Replace:

You can use Splitfunction and String.Joinnext:
您可以使用Split功能和String.Join下一步：
String.Join(" ", abc.Split('&', '|', '$'))
Test code:
测试代码：
static void Main(string[] args)
{
String abc = "asdfj$asdfj$sdfjn&sfnjdf|jnsdf|";
Console.WriteLine(String.Join(" ", abc.Split('&', '|', '$')));
}

It is possible to do with Regex, but if you prefer for some reason to avoid it, use the following static extension:
可以使用Regex，但如果您出于某种原因希望避免它，请使用以下静态扩展名：
public static string ReplaceMultiple(this string target, string samples, char replaceWith) {
if (string.IsNullOrEmpty(target) || string.IsNullOrEmpty(samples))
return target;
var tar = target.ToCharArray();
for (var i = 0; i < tar.Length; i++) {
for (var j = 0; j < samples.Length; j++) {
if (tar[i] == samples[j]) {
tar[i] = replaceWith;
break;
}
}
}
return new string(tar);
}
Usage:
用法：
var target = "abc123abc123";
var replaced = target.ReplaceMultiple("ab2", 'x');
//replaced will result: "xxc1x3xxc1x3"
