How to Implement Natural Sort Order for FileInfo Arrays in C#?

The natural sorting of the FileInfo array in C#realized

Question:

How to use the iComparer interface in C#to implement the natural sort of the FileInfo object?

Solution:

In order to achieve natural sorting, we can use the built -in function Strcmplogicalw in Windows API.

Implement:

First of all, create an internal class SafenatingMethods to suppress the non -host code security warning:

Next, define a naturstringcomparer class to implement iComparer

Interface:

<code class="language-csharp">[SuppressUnmanagedCodeSecurity]
internal static class SafeNativeMethods
{
    [DllImport("shlwapi.dll", CharSet = CharSet.Unicode)]
    public static extern int StrCmpLogicalW(string psz1, string psz2);
}</code>

Finally, create a naturFileInfonamecomparer class, using the natural order order to compare the FileInfo object:

<code class="language-csharp">public sealed class NaturalStringComparer : IComparer<string>
{
    public int Compare(string a, string b)
    {
        return SafeNativeMethods.StrCmpLogicalW(a, b);
    }
}</code>

This method is integrated with the Windows version of its running, providing a familiar sorting experience for your C#application.
