A method of implementing natural sorting in C#is to use the built -in function named

in Windows. You can access this function through P/Invoke:

StrCmpLogicalW

By using this function as a comparative function in the

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

implementation, natural sorting can be achieved. Examples as follows:

IComparer This method uses Windows's native implementation of natural sorting, thereby using the stability and intuitive behavior of the operating system. However, it should be noted that the logic of different versions of Windows may be different.
