Syncfusion Essential DocIO操作word檔案實用函數

Essential DocIO

.NET函式庫，能夠讀寫Microsoft Word文件。此元件為物件模型，與Microsoft Office COM類別庫相似，它不採用COM interop，以C#撰寫。如果系統內沒有安裝Microsoft Word，可以考慮此元件。

建立新的MS Word文件：支援建立包含文字、圖片、圖表、頁面和頁尾的MS Word文件。

文件格式化：支援格式化為通用的MS Word 報告。

文件產生基於範本：基於範本產生文檔，可以使用MS Word GUI設計文檔報告，然後使用DocIO向範本文件內動態填充資料。

文檔屬性：讀寫Word文檔的屬性設定。

轉換：支援使用Essential PDF將MS Word文件轉換為PDF。

進階特性：支援複製和合併多個MS Word文件為單一文件。
轉換HTML到word
public static byte[] ConvertHtmlToDoc(string html)
{
var document = new WordDocument();
IWSection section = document.AddSection();
IWParagraph para = section.AddParagraph();

string errorMessage = "";
bool valid = section.Body.IsValidXHTML(html, XHTMLValidationType.Strict, out errorMessage);
if (!valid)
throw new InvalidCastException(errorMessage + "<hr>" + html) ;
document.XHTMLValidateOption = XHTMLValidationType.Strict;
section.Body.InsertXHTML(html);
var outMem = new MemoryStream();

document.Save(outMem, FormatType.Doc);
outMem.Seek(0, SeekOrigin.Begin);
var content = new byte[outMem.Length];
outMem.Read(content, 0, content.Length);
outMem.Dispose();
document.Close();
return content;
}

產生Word的時候替換指定的文字
/// <summary>
/// 產生Word的時候取代指定的文字
/// </summary>
/// <param name="templatePath"></param>
/// <param name="FileName"></param>
/// <param name="replaysDictionary"></param>
public static void ReplaceDocContent(string templateFileName, string newFileName,
Dictionary<string, string> replaysDictionary)
{
IWordDocument document = new WordDocument();
document.Open(templateFileName, FormatType.Doc);
foreach (var rd in replaysDictionary)
{
if (string.IsNullOrEmpty(document.GetText())) continue;

document.Replace(rd.Key, rd.Value, false, false);
while (document.GetText().IndexOf(rd.Key) != -1)
document.Replace(rd.Key, rd.Value, false, false);
}
document.Save(newFileName, FormatType.Doc);
}

將文件加密碼保護
public static Stream SetDocProtect(byte[] docContent, string key)
{
var mem = new MemoryStream(docContent);
mem.Seek(0, SeekOrigin.Begin);

IWordDocument document = new WordDocument(mem, FormatType.Automatic);
document.Protect(ProtectionType.AllowOnlyFormFields, key);
var outMem = new MemoryStream();
document.Save(outMem, FormatType.Doc);
outMem.Seek(0, SeekOrigin.Begin);
return outMem;
}

在書籤位置建立一個表格
public static IWTable ReplaceTable(WordDocument document, string bookmarkName, DataTable data, string mergeColName , List<List<string>> mutilTableCaption)
{
if (document == null) throw new ArgumentNullException("document");
if (bookmarkName == null) throw new ArgumentNullException("bookmarkName");
if (data == null) throw new ArgumentNullException("data");
if (data.Columns.Count < 1) throw new ArgumentNullException("data");

int captionCount = mutilTableCaption != null && mutilTableCaption.Count > 0 ? mutilTableCaption.Count : 1;
WTable table = new WTable(document, true);

table.ResetCells(data.Rows.Count + captionCount, data.Columns.Count);

for (var colCount = 0; colCount < captionCount; colCount++)
{
for (var col = 0; col < data.Columns.Count; col++)
{
var paragraph = table.Rows[colCount].Cells[col].AddParagraph();

var caption = data.Columns[col].ColumnName;
if (mutilTableCaption != null && mutilTableCaption.Count > 0)
caption = mutilTableCaption[colCount][col];
var text = paragraph.AppendText(caption);
paragraph.ParagraphFormat.Horizo​​ntalAlignment = Syncfusion.DocIO.DLS.Horizo​​ntalAlignment.Center;
text.CharacterFormat.FontName = "宋體";
text.CharacterFormat.Bold = false;
text.CharacterFormat.FontSize = 10.5f;
}
}

for (var row = captionCount; row <= data.Rows.Count; row++)
for (var col = 0; col < data.Columns.Count; col++)
{
var paragraph = table.Rows[row].Cells[col].AddParagraph();
var text = paragraph.AppendText(data.Rows[row - captionCount][col] + "");

text.CharacterFormat.FontName = "宋體";
text.CharacterFormat.FontSize = 9f;
double val = 0;
if (double.TryParse(text.Text, out val))
{
text.Text = Math.Round(val, 2) + "";
//align right
paragraph.ParagraphFormat.Horizo​​ntalAlignment = Syncfusion.DocIO.DLS.Horizo​​ntalAlignment.Right;
table.Rows[row].Cells[col].CellFormat.VerticalAlignment = VerticalAlignment.Middle;
table.Rows[row].Cells[col].CellFormat.TextWrap = false;
}
}
//合併儲存格，向下合併
if (!string.IsNullOrEmpty(mergeColName))
for (var row = captionCount; row < table.Rows.Count; row++)
{
var cell = table.Rows[row].Cells[data.Columns[mergeColName].Ordinal];
cell.CellFormat.VerticalMerge = CellMerge.Start;
var text = data.Rows[row - captionCount][mergeColName] + "";
if (row > captionCount)
{
var priorCell = table.Rows[row - captionCount].Cells[data.Columns[mergeColName].Ordinal];
var findText = data.Rows[row - captionCount - 1][mergeColName] + "";
if (text.Equals(findText))
cell.CellFormat.VerticalMerge = CellMerge.Continue;
}
}

BookmarksNavigator bk = new BookmarksNavigator(document);
bk.MoveToBookmark(bookmarkName);

TextBodyPart body= bk.GetBookmarkContent();
bk.DeleteBookmarkContent(true);

bk.InsertTable(table);
return table;
}
