# 简单的 Nugget

# CHTCHSConv

TIP

一个 AspnetCore 下简繁体转换的库。

1.之前 netFrameWork 下使用 vb 的两个方法进行转换

Strings.StrConv(s_souce, VbStrConv.SimplifiedChinese);//转简体
Strings.StrConv(s_souce, VbStrConv.TraditionalChinese);//转繁体

2.netcore

//nugget安装,然后引用:using Microsoft.International.Converters.TraditionalChineseToSimplifiedConverter;
ChineseConverter.Convert(s_souce, ChineseConversionDirection.TraditionalToSimplified);//转简体
ChineseConverter.Convert(s_souce, ChineseConversionDirection.SimplifiedToTraditional);//转繁体

# 判断中文

参考

//netcore项目,需要提前安装:System.Text.Encoding.CodePages.dll , CodePage的库,
//并且使用的时候:需要进行注册
//Encoding.RegisterProvider(CodePagesEncodingProvider.Instance);
