我不知道如何重新配置以下内容以考虑"系统字符串比较":
.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..我如何重写它以考虑到替换的"系统字符串比较"部分?
只是...告诉它你想要什么比较类型;例如,对于序号忽略大小写替换:
.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);
有关每个选项的功能的说明,请查看StringComparison
。一般来说,您不应该使用CurrentCulture
/CurrentCultureIgnoreCase
进行硬编码系统式替换;基于区域性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
比更清晰(IMO(""
真的没有任何好处。
