c# - 有 .net 的 Css 编写器吗？

Question

我注意到微软已经实现了一个内部的 CssTextWriter

internal sealed class CssTextWriter : TextWriter
{
  ....
}

有 .net 的 Css 编写器吗？

例如我想写这样的代码:

CssTextWriter writer = new CssTextWriter(textWriter);
writer.WriteBeginCssRule("p");
writer.WriteAttribute("font-family", "Arial,Liberation Sans,DejaVu Sans,sans-serif");
writer.WriteEndCssRule();

上面的代码将输出到流中，如下所示:

p { font-family: Arial,Liberation Sans,DejaVu Sans,sans-serif; }

无点 http://www.dotlesscss.org/看起来它可以完成这项工作，但有点太多了我只需要一个 clss

我封装了对内部 Microsoft 类的调用(是的，这很顽皮，它可能会在未来的 .net 等版本中消失......)

public class CssTextWriter
{
    public CssTextWriter(TextWriter writer)
    {
        if (writer == null)
        {
            throw new ArgumentNullException("writer");
        }

        this.Writer = writer;
        this.Initialize();
    }

    /// <summary>
    /// Gets the writer.
    /// </summary>
    /// <value>
    /// The writer.
    /// </value>
    public TextWriter Writer { get; private set; }

    /// <summary>
    /// Gets or sets the internal CSS text writer.
    /// </summary>
    /// <value>
    /// The internal CSS text writer.
    /// </value>
    private object InternalCssTextWriter
    {
        get;

        set;
    }

     public void WriteBeginCssRule(string selector)
    {
        this.InternalCssTextWriter.InvokeMethod("WriteBeginCssRule", new[] { selector });
    }

    public void WriteEndCssRule()
    {
        this.InternalCssTextWriter.InvokeMethod("WriteEndCssRule");
    }

    public void WriteAttribute(string name, string value)
    {
        this.InternalCssTextWriter.InvokeMethod("WriteAttribute", new[] { name, value }, new Type[] { typeof(string), typeof(string) });
    }

    public void Write(string value)
    {
        this.InternalCssTextWriter.InvokeMethod("Write", new[] { value }, new Type[] { typeof(string) });
    }

    public void WriteAttribute(HtmlTextWriterStyle key, string value)
    {
        this.InternalCssTextWriter.InvokeMethod("WriteAttribute", new object[] { key, value }, new Type[] { typeof(HtmlTextWriterStyle), typeof(string) });
    }

    private void Initialize()
    {
        Type internalType = typeof(System.Web.UI.HtmlTextWriter).Assembly.GetType("System.Web.UI.CssTextWriter");
        ConstructorInfo ctor = internalType.GetConstructors(BindingFlags.Instance | BindingFlags.Public)[0];
        this.InternalCssTextWriter = ctor.Invoke(new[] { this.Writer });
    }
}
