使用CompareStringEx来重新排序

为了像Windows一样，对于 字符串保证排序不会乱，可以自定义排序方法。

这里采用CompareStringEx来实现。

第一步，声明CompareStringEx

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

static readonly Int32 NORM_IGNORECASE = 0x00000001; static readonly Int32 NORM_IGNORENONSPACE = 0x00000002; static readonly Int32 NORM_IGNORESYMBOLS = 0x00000004; static readonly Int32 LINGUISTIC_IGNORECASE = 0x00000010; static readonly Int32 LINGUISTIC_IGNOREDIACRITIC = 0x00000020; static readonly Int32 NORM_IGNOREKANATYPE = 0x00010000; static readonly Int32 NORM_IGNOREWIDTH = 0x00020000; static readonly Int32 NORM_LINGUISTIC_CASING = 0x08000000; static readonly Int32 SORT_STRINGSORT = 0x00001000; static readonly Int32 SORT_DIGITSASNUMBERS = 0x00000008;   static readonly String LOCALE_NAME_USER_DEFAULT = null; static readonly String LOCALE_NAME_INVARIANT = String.Empty; static readonly String LOCALE_NAME_SYSTEM_DEFAULT = "!sys-default-locale";   [DllImport("kernel32.dll", CharSet = CharSet.Unicode)] static extern Int32 CompareStringEx(   String localeName,   Int32 flags,   String str1,   Int32 count1,   String str2,   Int32 count2,   IntPtr versionInformation,   IntPtr reserved,   Int32 param );

第二步，实现IComparer接口：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28

class LexicographicalComparer : IComparer<String> {     readonly String locale;     public LexicographicalComparer() : this(CultureInfo.CurrentCulture) { }     public LexicographicalComparer(CultureInfo cultureInfo) {     if (cultureInfo.IsNeutralCulture)       this.locale = LOCALE_NAME_INVARIANT;     else       this.locale = cultureInfo.Name;   }     public Int32 Compare(String x, String y) {     // CompareStringEx return 1, 2, or 3. Subtract 2 to get the return value.     return CompareStringEx(       this.locale,       SORT_DIGITSASNUMBERS, // Add other flags if required.       x,       x.Length,       y,       y.Length,       IntPtr.Zero,       IntPtr.Zero,       0) - 2;   }   }

第三步，调用如下：

?

1 2	var names = new [] { "2.log", "10.log", "1.log" }; var sortedNames = names.OrderBy(s => s, new LexicographicalComparer());
