我一直在网上寻找有关如何在RDLC文本框中添加行高或行距的答案，但无济于事。

我也尝试过，但是在导出为PDF时不起作用。为了再次确认这一点，我创建了一个简单的html文件，使用这种样式，我可以实现所需的效果。

无论如何，我的文本框的内容是动态的，因此它的长度可以更改。如果这是固定行，那么我只需根据需要添加 或Environment.NewLine。

文本框：

HTML-将HTML标签解释为样式

=Parameters!DatePrinted.Value & "<br /><br /><br /><br /><br /><br />" &
"This is to certify that <b>" & UCase(Parameters!Name.Value) & "</b> is currently enrolled in the <b>" & Parameters!CurrentTerm.Value & "</b> trimester of School Year <b>" & Parameters!CurrentSchoolYear.Value & "</b> in the <b>" & Parameters!DegreeProgram.Value & "</b> degree program at the best school in the universe. S/He was admitted into the College on the <b>" & Parameters!FirstTerm.Value & "</b> trimester of School Year <b>" & Parameters!FirstSchoolYear.Value & "</b>."
& "<br /><br /><br />" &
"This certification is being issued upon the request of <b>" & Parameters!Name.Value & "</b> for <b>" & Parameters!SpecificPurpose.Value & "</b>."
& "<br /><br /><br /><br /><br /><br />" &
"<b>Some Name</b>"
& "<br />" &
"Position"

我已经尝试过了。

=Parameters!DatePrinted.Value & "<br /><br /><br /><br /><br /><br />" &
"<p style='line-height: 1.5;'>" & 
"This is to certify that <b>" & UCase(Parameters!Name.Value) & "</b> is currently enrolled in the <b>" & Parameters!CurrentTerm.Value & "</b> trimester of School Year <b>" & Parameters!CurrentSchoolYear.Value & "</b> in the <b>" & Parameters!DegreeProgram.Value & "</b> degree program at the best school in the universe. S/He was admitted into the College on the <b>" & Parameters!FirstTerm.Value & "</b> trimester of School Year <b>" & Parameters!FirstSchoolYear.Value & "</b>."
& "</p>"
& "<br /><br /><br />" &
"<p style='line-height: 1.5;'>" &
"This certification is being issued upon the request of <b>" & Parameters!Name.Value & "</b> for <b>" & Parameters!SpecificPurpose.Value & "</b>."
& "</p>"
& "<br /><br /><br /><br /><br /><br />" &
"<b>Some Name</b>"
& "<br />" &
"Position"

当前输出：

使用""：

预期输出：

请忽略预期输出中的缩进。我重复使用了Line Height in SSRS帖子中的图片。

如果现有的自定义代码要为文本框内的每个新行添加 或Environment.NewLine，则肯定会有所帮助。我不精于报表中的自定义代码，因此不胜感激。

仍然没有使用RDLC或SSRS的直接解决方案。我改为使用iTextSharp，可以轻松满足我的要求。

FontFactory.RegisterDirectories();
Font tnr = FontFactory.GetFont("Times New Roman", 12f, Font.NORMAL, BaseColor.BLACK);
Font tnr_bold = FontFactory.GetFont("Times New Roman", 12f, Font.BOLD, BaseColor.BLACK);
Font tnr_italic = FontFactory.GetFont("Times New Roman", 12f, Font.ITALIC, BaseColor.BLACK);

List<IElement> elements = new List<IElement>();

Paragraph p1 = new Paragraph(FormatUtility.FormatDate3(DateTime.Now), tnr);

p1.SetLeading(0f, 2f); // This is the line height/line spacing

elements.Add(p1);
elements.Add(Chunk.NEWLINE);
elements.Add(Chunk.NEWLINE);

Paragraph p2 = new Paragraph();

p2.SetLeading(0f, 2f); // This is the line height/line spacing
p2.Add(new Chunk("This is to certify that ", tnr));
p2.Add(new Chunk(name.ToUpper(), tnr_bold));
p2.Add(new Chunk(" is currently enrolled in the ", tnr));
.
.
.
p2.Add(new Chunk(" trimester of School Year ", tnr));
p2.Add(new Chunk(currentSchoolYearTxt, tnr_bold));
p2.Add(new Chunk(" in the ", tnr));
p2.Add(new Chunk(degreeProgram, tnr_bold));
p2.Add(new Chunk(" degree program at the best school in the universe. S/He was admitted into the College on ", tnr));
.
.
.
p2.Add(new Chunk(" trimester of School Year ", tnr));
p2.Add(new Chunk(firstSchoolYearTxt, tnr_bold));
p2.Add(new Chunk(".", tnr));

elements.Add(p2);
elements.Add(Chunk.NEWLINE);

Paragraph p3 = new Paragraph();

p3.SetLeading(0f, 2f); // This is the line height/line spacing
p3.Add(new Chunk("This certification is being issued upon the request of ", tnr));
p3.Add(new Chunk(name, tnr_bold));
p3.Add(new Chunk(" for ", tnr));
p3.Add(new Chunk(specificPurpose, tnr_bold));
p3.Add(new Chunk(".", tnr));

elements.Add(p3);
elements.Add(Chunk.NEWLINE);
elements.Add(Chunk.NEWLINE);
elements.Add(new Paragraph("Someone Name", tnr_bold));
elements.Add(new Paragraph("Position", tnr));

byte[] renderedBytes = CreatePDF(PageSize.LETTER, elements, 72f, 72f, 216f, 72f);

和

private byte[] CreatePDF(Rectangle pageSize, IList<IElement> elements, float marginLeft = 0f, float marginRight = 0f, float marginTop = 0f, float marginBottom = 0f)
{
    byte[] renderedBytes = null;

    using (MemoryStream ms = new MemoryStream())
    {
        // Margins: 72f = 1 inch
        using (Document document = new Document(pageSize, marginLeft, marginRight, marginTop, marginBottom))
        {
            PdfWriter pdf = PdfWriter.GetInstance(document, ms);

            document.Open();

            foreach (IElement element in elements)
            {
                document.Add(element);
            }

            document.Close();

            renderedBytes = ms.ToArray();

            return renderedBytes;    
        }
    }
}

我使用以下方法几乎对RDLC达到了类似的效果：

string content = "Date <br/><br/><br/><br/><br/> This is to certify that <b>(NAME)</b> is currently enrolled in the <b>(CurrentTerm)</b> trimester of School Year <b>(CurrentSY)</b> in the <b>(Degree Program)</b> degree program at the best school in the universe. S/He was admitted into the College on <b>(FirstTerm)</b> trimester of School Year <b>(FirstSY)</b>. <br/><br/><br/> This certification is being issued upon the request of <b>(Name)</b> for <b>(specific purpose/s)</b>. <br/><br/><br/><br/><br/> <b>Some Name</b> <br/> Position";

content = content
        .Replace("(NAME)", name.ToUpper()); // Replace necessary strings with variable values

content = SplitByBreak(content, 85);

和

public static string SplitByBreak(string text, int length)
{
    List<string> ignoreList = new List<string>()
    {
        "<b>", 
        "</b>", 
        "<i>", 
        "</i>"
    };
    string br = "<br/>";
    string newText = string.Empty;
    string newLine = string.Empty;

    // Make sure that <br/> is the standard break.
    text = text.Replace("<br>", br);

    string[] split = text.Split(new[] { ' ' }, StringSplitOptions.RemoveEmptyEntries);

    for (int i = 0; i < split.Length; i++)
    {
        string testLine = string.Format("{0} {1}", newLine, split[i]).Trim();
        string temp = testLine;
        int lastIndexBr = testLine.LastIndexOf(br);

        // Count from the last index of <br/>.
        if (lastIndexBr >= 0)
        {
            temp = temp.Substring(lastIndexBr + br.Length);
        }

        // Do not include the length from the ignore list. -Eph 10.19.2018
        foreach (string s in ignoreList)
        {
            temp = temp.Replace(s, string.Empty);
        }

        if (temp.Length > length)
        {
            newText = string.Format("{0} {1} {2}{2}", newText, newLine, br).Trim();
            newLine = split[i];
        }
        else
        {
            testLine = string.Format("{0} {1}", newLine, split[i]).Trim();
            newLine = testLine;
        }
    }

    newText = string.Format("{0} {1}", newText, newLine).Trim();

    return newText;
}

我创建的这个函数很好，但是它只是为每个 长度的字符串添加n而忽略了ignoreList内部的标签。这仅对字符宽度相同但对我不起作用的字体有用。
