Dotnet Core - 在 'string.Replace(string, string?)' 上收到警告说使用 'string.Replace(string, string?, System.StringComparison)'

Question

我在 "Replace"

上收到以下警告

我不知道如何重新配置以下内容以考虑 'System.StringComparison':

                            .Replace("and", "&")
                            .Replace("substringof", string.Empty)
                            .Replace("(", string.Empty)
                            .Replace(")", string.Empty)
                            .Replace("'", string.Empty)
                            .Replace(" ", string.Empty)
                            .Replace("eq", ",")

每一行都抛出了一个警告..

我正在使用 VS2019，这些警告来自 Roslyn 编译器。我想摆脱警告..如何重写它以考虑替换的 'System.StringComparison' 部分？

Answer 1

只是...告诉它你想要什么比较类型；例如，对于 ordinal-ignore-case 替换：

    .Replace("and", "&", StringComparison.OrdinalIgnoreCase)
    .Replace("substringof", string.Empty, StringComparison.OrdinalIgnoreCase)
    .Replace("(", string.Empty, StringComparison.OrdinalIgnoreCase)
    .Replace(")", string.Empty, StringComparison.OrdinalIgnoreCase)
    .Replace("'", string.Empty, StringComparison.OrdinalIgnoreCase)
    .Replace(" ", string.Empty, StringComparison.OrdinalIgnoreCase)
    .Replace("eq", ",", StringComparison.OrdinalIgnoreCase);

有关每个选项功能的说明，请查看 StringComparison。一般来说，您不应该使用 CurrentCulture / CurrentCultureIgnoreCase 进行硬编码的类系统替换；基于文化的替换对于面向用户的替换更为典型（想想：ctrl+f）。作为旁注，使用 string.Empty 比使用更清晰的 (IMO) "".

确实没有任何好处
