旧
private string Check_long(string input)
{
input = input.Replace("cool", "supercool");
input = input.Replace("cool1", "supercool1");
input = input.Replace("cool2", "supercool2");
input = input.Replace("cool3", "supercool3");
return input;
}
新
private string Check_short(string input)
{
input = Regex.Replace(input, "cool", "supercool", RegexOptions.IgnoreCase);
input = Regex.Replace(input, "cool1", "supercool1", RegexOptions.IgnoreCase);
input = Regex.Replace(input, "cool2", "supercool2", RegexOptions.IgnoreCase);
input = Regex.Replace(input, "cool3", "supercool3", RegexOptions.IgnoreCase);
return input;
}
旧的解决方案与string.replace
是工作就好了。但它不支持不区分大小写。因此,我不得不检查 Regex.Replace
,但现在它不会工作。这是为什么呢?
The old solution with String.Replace
was working just fine. But it didn't support case-insensitivity. So I had to check for Regex.Replace
, but now it won't work. Why is that ?
推荐答案
您新的code应该很好地工作。请注意,您也可以使用捕获组保留您输入的情况下:
Your new code should work fine. Note that you can also retain the case of your input using a capture group:
private string Check_short(string input)
{
return Regex.Replace(input, "(cool)", "super$1", RegexOptions.IgnoreCase);
}
