CsvHelper设置默认的自定义TypeConverter

本文介绍了CsvHelper设置默认的自定义TypeConverter的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

使用CsvHelper时，当我想要一个自定义解析器时(例如，我希望输入字符串为"f"的 MyBooleanConverter 为假，"t"为假)是真实的").但是对于每个类，我都必须编写映射器:

With CsvHelper, when I want a custom parser (for example, I want a MyBooleanConverter with the input string is "f" will be false, "t" will be "true"). But with every class I have to write mapper:

public sealed class MyClassMap : CsvClassMap<MyClass> { public MyClassMap() { Map( m => m.Id ).Index( 0 ).TypeConverter<MyBooleanConverter>(); } }

或

[CsvHelper.TypeConversion.TypeConverter( typeof( MyBooleanConverter) )] public Boolean MyObjectProperty { get; set; }

如何为每个布尔字段和每个类将 MyBooleanConverter 设置为默认值?

How can I set MyBooleanConverter as default for every boolean field and every Class?

推荐答案

CsvHelper库公开了静态的 TypeConverterFactory .您只需删除默认的布尔转换器并添加自定义转换器即可替换它.

The CsvHelper library exposes a static TypeConverterFactory. You can simply remove the default Boolean converter and add your custom converter to replace it.

TypeConverterFactory.RemoveConverter<bool>(); TypeConverterFactory.AddConverter<bool>(new MyBooleanConverter());
