我想要达到的效果
在我的c#应用程序中，我想从我的应用程序中的数据生成一个报告(word文档)，我认为最好的方法是使用我的应用程序中的数据源执行类似邮件合并的操作。
我已经试过了
- 我试着遵循这个邮件合并成文字然而，这使用GemBox，你需要支付
-
我试过使用Microsoft.Office.Interop.Word，但是我失败了当我不知道如何引用保存的模板文档时:
Dictionary<string, string> MailMerge = new Dictionary<string, string>() { { "ID", "123" }, { "Name", "Test" }, { "Address1", "Test" }, { "Address2", "Test" }, { "Address3", "Test" }, { "Address4", "Test" }, { "PostCode", "Test" }, { "Year End", "Test" }, { "SicCode", "123" }, }; Document doc = new Document(); doc.MailMerge.Execute(MailMerge);
我正在寻找一些关于进一步研究的指导，因为我相信一定有一个"标准"的方法来做这件事。
真不敢相信第三方软件为Word的接口功能收费数千元。在我的项目中，我已经完美地解决了这个邮件合并问题——没有第三方，对IIS没有特别的要求，只使用OpenXML。因此，将这4个函数添加到您的项目中:
public static void dotx2docx(string sourceFile, string targetFile)
{
MemoryStream documentStream;
using (Stream tplStream = File.OpenRead(sourceFile))
{
documentStream = new MemoryStream((int)tplStream.Length);
CopyStream(tplStream, documentStream);
documentStream.Position = 0L;
}
using (WordprocessingDocument template = WordprocessingDocument.Open(documentStream, true))
{
template.ChangeDocumentType(DocumentFormat.OpenXml.WordprocessingDocumentType.Document);
MainDocumentPart mainPart = template.MainDocumentPart;
mainPart.DocumentSettingsPart.AddExternalRelationship("http://schemas.openxmlformats.org/officeDocument/2006/relationships/attachedTemplate",
new Uri(targetFile, UriKind.Absolute));
mainPart.Document.Save();
}
File.WriteAllBytes(targetFile, documentStream.ToArray());
}

并像这样使用它们:
DataTable dt = new DataTable();
dt.Columns.Add("Date");
dt.Columns.Add("Today");
dt.Columns.Add("Addr1");
dt.Columns.Add("Addr2");
dt.Columns.Add("PreferContact");
dt.Columns.Add("TenantName");
//......
DataRow nr = dt.NewRow();
nr["Date"] = DateTime.Now.ToString("dd/MM/yyyy");
nr["Today"] = DateTime.Now.ToString("dd/MM/yyyy");
//......
dt.Rows.Add(nr);
string sourceFile = "c:my_template.docx"; //this is where you store your template
string filePath = "c:final.docx"; //this is where your result file locate
Mailmerge(sourceFile, filePath, nr, dt.Columns);
你的模板(c:my_template.docx)就像普通的。docx文件一样，你需要在其中指定你的字段:
<field>
<Today>
<DebtorName>
<DebtorADDR>
<DebtorEmail>
Dear <Dear>,
Congratulations on yourr property <PlanNo> <BuildAddress>. Your unit number is <LotNo> ...............
另外，如果您的某些字段包含换行符，请使用:
nr["Address"] = my_address_text_contains_line_breaks.Replace(Environment.NewLine, "MS_Doc_New_Line");
使用Microsoft.Office.Interop.Word非常简单。这里是一个简单的一步一步的教程，教你如何做到这一点。
用字符串替换合并字段的代码如下:
public static void TextToWord(string pWordDoc, string pMergeField, string pValue)
{
Object oMissing = System.Reflection.Missing.Value;
Object oTrue = true;
Object oFalse = false;
Word.Application oWord = new Word.Application();
Word.Document oWordDoc = new Word.Document();
oWord.Visible = true;
Object oTemplatePath = pWordDoc;
oWordDoc = oWord.Documents.Add(ref oTemplatePath, ref oMissing, ref oMissing, ref oMissing);
foreach (Word.Field myMergeField in oWordDoc.Fields)
{
Word.Range rngFieldCode = myMergeField.Code;
String fieldText = rngFieldCode.Text;
if (fieldText.StartsWith(" MERGEFIELD"))
{
Int32 endMerge = fieldText.IndexOf("\");
Int32 fieldNameLength = fieldText.Length - endMerge;
String fieldName = fieldText.Substring(11, endMerge - 11);
fieldName = fieldName.Trim();
if (fieldName == pMergeField)
{
myMergeField.Select();
oWord.Selection.TypeText(pValue);
}
}
}
}
原贴于此处和此处
如果您希望使用字典一次替换多个字段，请使用下面的代码:
public static void TextToWord(string pWordDoc, Dictionary<string, string> pDictionaryMerge)
{
Object oMissing = System.Reflection.Missing.Value;
Object oTrue = true;
Object oFalse = false;
Microsoft.Office.Interop.Word.Application oWord = new Microsoft.Office.Interop.Word.Application();
Microsoft.Office.Interop.Word.Document oWordDoc = new Microsoft.Office.Interop.Word.Document();
oWord.Visible = true;
Object oTemplatePath = pWordDoc;
oWordDoc = oWord.Documents.Add(ref oTemplatePath, ref oMissing, ref oMissing, ref oMissing);
foreach (Microsoft.Office.Interop.Word.Field myMergeField in oWordDoc.Fields)
{
Microsoft.Office.Interop.Word.Range rngFieldCode = myMergeField.Code;
String fieldText = rngFieldCode.Text;
if (fieldText.StartsWith(" MERGEFIELD"))
{
Int32 endMerge = fieldText.IndexOf("\");
Int32 fieldNameLength = fieldText.Length - endMerge;
String fieldName = fieldText.Substring(11, endMerge - 11);
fieldName = fieldName.Trim();
foreach (var item in pDictionaryMerge)
{
if (fieldName == item.Key)
{
myMergeField.Select();
oWord.Selection.TypeText(item.Value);
}
}
}
}
}
我也在使用同样的东西，但我有更多的复杂性。我还要检查if条件。word模板文件{如果«分期付款»=每月"那么表格将出现" "nothing to show"}
时，我使用上述代码共享的答案。对于c#中的if条件，我写了
Range rngFieldCode = myMergeField.Code;
String fieldText = rngFieldCode.Text.Trim();
if (fieldText.ToUpper().StartsWith("IF"))
{
myMergeField.UpdateSource();}
输出就像
{IF Monthly = Monthly "then table将出现" "nothing to show"}
但是期望的输出只是"then the table will appear"
