在C#中使用构建器模式和方法链接时返回字符串

using System.Text;

public class StringBuilderExample
{
    private StringBuilder _builder;

    public StringBuilderExample()
    {
        _builder = new StringBuilder();
    }

    public StringBuilderExample AddHeader(string text)
    {
        _builder.Append("<h1>").Append(text).Append("</h1>");
        return this;
    }

    public StringBuilderExample AddParagraph(string text)
    {
        _builder.Append("<p>").Append(text).Append("</p>");
        return this;
    }

    public StringBuilderExample AddLink(string url, string text)
    {
        _builder.Append("<a href='").Append(url).Append("'>").Append(text).Append("</a>");
        return this;
    }

    public string GetResult()
    {
        return _builder.ToString();
    }
}

public class Program
{
    public static void Main()
    {
        string result = new StringBuilderExample()
            .AddHeader("Welcome to my website")
            .AddParagraph("This is a paragraph about me.")
            .AddLink("https://www.example.com", "Click here for more information")
            .GetResult();

        Console.WriteLine(result);
    }
}
