2 年后，我刚回来用 MigraDoc 和 PDFsharp 做一些事情。为了让生活更轻松，我为样式创建了一个辅助函数，我想知道为什么它不能按预期工作？

所有字体分配都很好：字体系列、大小和类型以及颜色都正确。链接也被创建并且它们也可以工作。

但所有段落样式都被忽略。正如我在调试器中看到的那样，它们被分配给新样式，但它们没有被渲染。

这可能是关于段落和部分的规则，我不知道。

有人可以启发我吗？

// all styles by name/definition
public string allStyles = "";

private string style(string styleName)
      {
          if (allStyles.IndexOf(" " + styleName + " ") < 0)  // the stylename is new, so we create it..
          {
                string style = styleName + "   ";
                string fontChar = style[0].ToString();
                string fs = "";
                if (style[1] >= '0' & style[1] <= '9') fs += style.Substring(1, 1);
                if (style[2] >= '0' & style[2] <= '9') fs += style.Substring(2, 1);
                if (style[3] >= '0' & style[3] <= '9') fs += style.Substring(3, 1);
                int fontSize = Convert.ToInt32(fs);
// now digits after position 2 may be ignored
// we use the rest of the stylename for the rest of the style details..
                string styleName2 = styleName.Substring(1);
// add base style to the document style cache       
                Style newStyle = document.AddStyle(styleName, "Normal");
// now we modify the new style..:
                newStyle.Font.Bold = styleName.IndexOf("B") >= 0;
                newStyle.Font.Italic = styleName.IndexOf("I") >= 0;
                if (fontChar == "A") newStyle.Font.Name = "Arial";                
// .. 25 more fonts omitted..
// ..
                if (styleName.IndexOf("a") >= 0) newStyle.Font.Color = MigraDoc.DocumentObjectModel.Colors.AntiqueWhite;
// .. 25 more colors omitted..
// ..
// .. here a a few ParagraphFormat styles, all of which don't work!!
                if (styleName2.IndexOf("L") >= 0) newStyle.ParagraphFormat.Alignment = ParagraphAlignment.Left;
                else if (styleName2.IndexOf("R") >= 0) newStyle.ParagraphFormat.Alignment = ParagraphAlignment.Right;
                else if (styleName2.IndexOf("C") >= 0) newStyle.ParagraphFormat.Alignment = ParagraphAlignment.Center;
                else if (styleName2.IndexOf("J") >= 0) newStyle.ParagraphFormat.Alignment = ParagraphAlignment.Justify;
                if (styleName2.IndexOf("____") >= 0) newStyle.ParagraphFormat.SpaceAfter = 15;
                else if (styleName2.IndexOf("___") >= 0) newStyle.ParagraphFormat.SpaceAfter = 10;
                else if (styleName2.IndexOf("__") >= 0) newStyle.ParagraphFormat.SpaceAfter = 6;
                else if (styleName2.IndexOf("_") >= 0) newStyle.ParagraphFormat.SpaceAfter = 3;

// add stylename to the collection string
                allStyles += "  " + styleName + "  ";
            }
// return the name after creating and modifying the style
            return styleName;                


// a plain FT output function           
        public void writeFT(Section currentSection, string text, string styl, bool newParagraph)

            HL.AddFormattedText(text, style(styl));

要设置段落样式，只需使用currentParagraph.Style = style(styl);. 如果您想为段落使用该样式，您可以使用AddText()而不是添加文本（您仍然可以调用以添加具有不同字符格式的文本）。AddFormattedText()AddFormattedText()

AddFormattedText 仅支持字符格式（不支持段落格式）。合乎逻辑，因为它是段落的一部分。

您的 API 应该考虑到这一点。
