c# 自定义字符串排序

场景：List 需要按照某字段属性排序

字段数据存在如1，2，F1，F2，楼层3，F3，楼层11，

需要按照1，2，F1，F2，F3，楼层3，楼层11 来排序

public class NumericStringComparer : IComparer<string>

    public static readonly NumericStringComparer Instance = new NumericStringComparer();

    public static readonly string RegexNum = @"^[0-9]+";

                }
                else if (xIsHan)
                {
                    return -1;
                }
                else if (yIsHan)
                {
                    return 1;
                }
                else if (xIsLetter)
                {
                    return -1;
                }
                else if (yIsLetter)
                {
                    return 1;
                }
                else if (xIsSymbol)
                {
                    return -1;
                }
                else if (yIsSymbol)
                {
                    return 1;
                }

                return string.Compare(x, y);
            }
        }
    }
}

示例：

list.OrderBy(s => s.Name, new NumericStringComparer());
