我只是使用 OpenXML 来操作 docx 文档。我有带有类似符号的模板 {{用户名}} {{用户表}} {{signatureImage}} 等
我需要用表格、图像等替换这些文本。如何在 Openxml 中做到这一点? 我正在使用 C# .Net core 3.1 和 OpenXML 2.5
我的代码是这样的,但是表格仍然没有插入到正确的位置:
var fileName = Path.Combine(_hostingEnv.WebRootPath, "test/test.docx");
var fileNameResult = Path.Combine(_hostingEnv.WebRootPath, "test/result.docx");
byte[] byteArray = System.IO.File.ReadAllBytes(fileName);
using (MemoryStream stream = new MemoryStream())
{
stream.Write(byteArray, 0, (int)byteArray.Length);
using (WordprocessingDocument wd = WordprocessingDocument.Open(stream, true))
{
Table table = new Table();
// Create a TableProperties object and specify its border information.
TableProperties tblProp = new TableProperties(
new TableBorders(
new TopBorder()
{
Val =
new EnumValue<BorderValues>(BorderValues.Dashed),
Size = 24
},
new BottomBorder()
{
Val =
new EnumValue<BorderValues>(BorderValues.Dashed),
Size = 24
},
new LeftBorder()
{
Val =
new EnumValue<BorderValues>(BorderValues.Dashed),
Size = 24
},
new RightBorder()
{
Val =
new EnumValue<BorderValues>(BorderValues.Dashed),
Size = 24
},
new InsideHorizontalBorder()
{
Val =
new EnumValue<BorderValues>(BorderValues.Dashed),
Size = 24
},
new InsideVerticalBorder()
{
Val =
new EnumValue<BorderValues>(BorderValues.Dashed),
Size = 24
}
)
);
// Append the TableProperties object to the empty table.
table.AppendChild<TableProperties>(tblProp);
// Create a row.
TableRow tr = new TableRow();
// Create a cell.
TableCell tc1 = new TableCell();
// Specify the width property of the table cell.
tc1.Append(new TableCellProperties(
new TableCellWidth() { Type = TableWidthUnitValues.Dxa, Width = "2400" }));
// Specify the table cell content.
tc1.Append(new Paragraph(new Run(new Text("some text"))));
// Append the table cell to the table row.
tr.Append(tc1);
// Create a second table cell by copying the OuterXml value of the first table cell.
TableCell tc2 = new TableCell(tc1.OuterXml);
// Append the table cell to the table row.
tr.Append(tc2);
// Append the table row to the table.
table.Append(tr);
var tblStr = table.ToString();
//wd.MainDocumentPart.Document.Body.Append(table);
Text tablePl = wd.MainDocumentPart.Document.Body.Descendants<Text>().Where(x => x.Text == "{{tableOfUsers}}").First();
if(tablePl != null)
{
var parent = tablePl.Parent;
tablePl.Parent.InsertAfter<Table>(table, tablePl);
tablePl.Remove();
}
string docText = null;
using (StreamReader sr = new StreamReader(wd.MainDocumentPart.GetStream()))
{
docText = sr.ReadToEnd();
}
Regex regexText = new Regex("{{name}}");
docText = regexText.Replace(docText, "Claire " + DateTime.Now.ToString());
// Regex regextable = new Regex("{{tableOfUsers}}");
// docText = regextable.Replace(docText, tblStr);
using (StreamWriter sw = new StreamWriter(wd.MainDocumentPart.GetStream(FileMode.Create)))
{
sw.Write(docText);
}
}
await System.IO.File.WriteAllBytesAsync(fileNameResult, stream.ToArray());
}
_fileRepo.SetPath("test");
string fileName2 = "result.docx";
var data = await _fileRepo.DownloadFile(fileName2);
return File(data, "application/octet-stram", "filename.docx");
}
我的 docx 文件看起来像
你好{{name}}
这是用户列表:{{tableOfUsers}}
真诚的,
{{签名图片}}
使用下面的代码插入表格:
............
string tablePlaceholder = "{{tableOfUsers}}";
Text tablePl = wd.MainDocumentPart.Document.Body
.Descendants<Text>()
.Where(x => x.Text.Contains(tablePlaceholder))
.First();
if (tablePl != null)
{
//Insert the table after the paragraph.
var parent = tablePl.Parent.Parent.Parent;
parent.InsertAfter(table, tablePl.Parent.Parent);
tablePl.Text = tablePl.Text.Replace(tablePlaceholder, "");
wd.MainDocumentPart.Document.Save();
}
string docText = wd.MainDocumentPart.Document.Body.OuterXml;
Regex regexText = new Regex("{{name}}");
docText = regexText.Replace(docText, "Claire " + DateTime.Now.ToString());
wd.MainDocumentPart.Document.Body = new Body(docText);
wd.MainDocumentPart.Document.Save();
.............
您正在代码中查找
{{table}}
{{tableOfUsers}}
。尝试DocxTemplater for Net。这是一个完全可以完成您想要做的事情的库。
使用模板语法创建模板文档
This Text: {{ds.Title}} - will be replaced
打开模板,添加模型并将结果存储到文件中
var template = DocxTemplate.Open("template.docx");
template.BindModel("ds", new { Title = "Some Text"});
template.Save("generated.docx");
它可以处理表格、图像、Html 等等
