C#根据中文首字母排序

第一种方式：
这种方式会受制于服务器的区域和语言设置。
1.首先添加一个排序类ChineseNameComparer

public class ChineseNameComparer : IComparer<string>
{public int Compare(string x, string y){if (x == null || y == null)return 0;var xFirstChar = x.Substring(0, 1);var yFirstChar = y.Substring(0, 1);return string.Compare(xFirstChar, yFirstChar, StringComparison.CurrentCulture);}
}

2.list排序

list = list.OrderBy(t => t.ChineseName, new ChineseNameComparer()).ToList();

第二种方式：引入Microsoft.International.Converters.PinYinConverter包

private string GetPinyin(string chineseName){string pinyin = string.Empty;foreach (char c in chineseName){if (ChineseChar.IsValidChar(c)){ChineseChar chineseChar = new ChineseChar(c);pinyin += chineseChar.Pinyins[0][0];}else{pinyin += c;}}return pinyin;}

获取到拼音后再list排序。
