Question

我在C＃中有一个字符串列表。它在列表中的字符串中间的某处包含以下子字符串。该清单未订购。我想根据其中的以下条目订购此列表：

Email
FirstName
LastName
Country
Province
Phone
Fax

按此顺序。

例如，如果原始列表包含以下条目：

The field Province required 5 letters
Wrong Email
Phone is required
FirstName should contain min of 5 letters
The field Fax requires 10 digits
Enter a valid LastName
Fax is required
The field Phone requires 10 digits

需要按如下方式排序：

Wrong Email
FirstName should contain min of 5 letters
Enter a valid LastName
The field Province required 5 letters
Phone is required
The field Phone requires 10 digits
Fax is required
The field Fax requires 10 digits

可能是这样的。

var order = new List<string>()
{
    "Email",
    "FirstName",
    "LastName",
    "Country",
    "Province",
    "Phone",
    "Fax",
};

var lines = new List<string>()
{
    "The field Province required 5 letters",
    "Wrong Email",
    "Phone is required",
    "FirstName should contain min of 5 letters",
    "The field Fax requires 10 digits",
    "Enter a valid LastName",
    "Fax is required",
    "The field Phone requires 10 digits",
};

Func<string, int> calc = s => Regex.Matches(s, @"\w+").Cast<Match>()
                                .Select(m => m.Value)
                                .Max(x => order.IndexOf(x));

var result = lines.OrderBy(l => calc(l)).ToList();

如果某行不包含您设置中的任何关键字，则可能需要修复此代码...

顺便说一句：对于像

这样的案例，您的问题并不明确

Wrong Email or Fax number
