C# 中的 URL Slugify 算法

csharp
public static string Slugify(string input)
{
    // 将字符串转换为小写并去除首尾空格
    string slug = input.ToLower().Trim();
    // 替换非法字符为连接符
    slug = Regex.Replace(slug, @"\s", "-"); // 替换空格
    slug = Regex.Replace(slug, @"[^a-z0-9\s-]", ""); // 替换非字母、数字和连接符
    // 去除连续的连接符
    slug = Regex.Replace(slug, @"-{2,}", "-");
    return slug;
}

csharp
string input = "Hello World! This is an example URL.";
string slug = Slugify(input);
Console.WriteLine(slug); // 输出: hello-world-this-is-an-example-url
