FieldConverter ConverterKind.Date 不支持 "dd/MM/yyyy HH:mm:ss.ffffff"
FieldConverter ConverterKind.Date not supporting "dd/MM/yyyy HH:mm:ss.ffffff"
我正在尝试使用文件帮助程序库读取带分隔符的平面文件。
[FieldConverter(ConverterKind.Date, "yyyy/MM/dd HH:mm:ss.ffffff")]
public DateTime DateOfInteraction;
但我收到以下异常

我不明白为什么我会收到异常，即使日期格式字符串是有效的。以下代码片段提供正确的输出...
Console.WriteLine("Started: {0:dd/MM/yyyy HH:mm:ss.ffffff}", DateTime.Now);
自定义日期格式字符串中的“/”是特定于文化的 DateSeparator。所以它被你的文化的日期分隔符所取代。转换时您必须在文化设置中指定 InvariantCulture 而转换
