RDLC 文本框行 Height/Line 间距
RDLC Textbox Line Height/Line Spacing
版本：http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition
我一直在网上寻找有关如何在 RDLC 文本框中添加行高或行间距的答案，但无济于事。
我也试过 <p style="line-height: 1.5;"> 但导出为 PDF 时它不起作用。为了仔细检查这一点，我创建了一个简单的 html 文件，并使用这种样式实现了我想要的效果。
无论如何，我的文本框的内容是动态的，所以它的长度可以改变。如果这是固定行，那么我会根据需要简单地添加 <br/> 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>."

"<b>Some Name</b>"
& "<br />" &
"Position"
我试过了..
=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.

& "</p>"

当前输出：
与"<p style='line-height: 1.5;'>":

如果现有自定义代码可以为文本框中的每一行添加 <br/> 或 Environment.NewLine，那么它肯定会有所帮助。我不熟悉报告中的自定义代码，所以我将不胜感激。
仍然没有使用 RDLC 或 SSRS 的直接解决方案。我改为使用 iTextSharp 并且很容易满足我的要求。

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())

using (Document document = new Document(pageSize, marginLeft, marginRight, marginTop, marginBottom))

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在 RDLC 上实现了类似的效果：
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，但它只是为每个长度为 n 的字符串添加 <br/><br/>，同时忽略 ignoreList 内的标签。这仅对具有相同字符宽度的字体有用，这对我不起作用。
