linq 字母数字组合字符串排序

Posted 2023-03-02

我在数据库有一个字段的值是这样的，字符串类型
var query= from top in context .Yield
select new SizeDTO()

size= context .size
.ToList();
结果是：2 j11 j11.5 2.5 3 4 k5 b6.5 7 8 9 10
我想对一结果排序，之前我想这样排的
.ToList().OrderBy(c => Convert.ToDouble(c.size_nm.ToString()));转型后排，但是里面有些值有字母，我也想过使用Substring去截取之后转，但是又有纯数字！求大神指导

        static void Main(string[] args)
        
            string[] all = new string[]  "a2", "b6", "4", "5", "3", "cc1.1" ;

            var v = all.Select(a => new
            
                a,
                ints = new string(a.Where(c => char.IsDigit(c) ||
                    c == '.').ToArray())
            ).Select(b => new
            
                s = b.a,
                i = Convert.ToDouble(b.ints)
            ).OrderBy(o => o.i).Select(r => r.s);

            foreach (var x in v)
                Console.WriteLine(x);
            Console.ReadLine();
        

参考技术A static void Main(string[] args)

string[] all = new string[] "a2", "b6", "4", "5", "3", "cc1.1" ;

var v = all.Select(a => new

a,
ints = new string(a.Where(c => char.IsDigit(c) ||
c == '.').ToArray())
).Select(b => new

s = b.a,
i = Convert.ToDouble(b.ints)
).OrderBy(o => o.i).Select(r => r.s);

foreach (var x in v)
Console.WriteLine(x);
Console.ReadLine();
参考技术B 取第一个字母用 编码排序呢？
