Sending text to Mail-Merge Fields in Microsoft Wor

2019-02-11 11:06发布

I'm using the following code to send a text to a simple word template I've set up just with a single MergeField at present to test I can get this working.
The code I am using is as follows:

public static void ReplaceMailMergeField(string pWordDoc, string pMergeField, string pValue)
{
    object docName = pWordDoc;
    object missing = Missing.Value;
    Word.MailMerge mailMerge;
    Word._Document doc;
    Word.Application app = new Word.Application();
    app.Visible = false;
    doc = app.Documents.Open(ref docName, ref missing, ref missing, ref missing, ref missing,
                                          ref missing, ref missing, ref missing, ref missing,
                                          ref missing, ref missing, ref missing, ref missing,
                                          ref missing, ref missing, ref missing);
    mailMerge = doc.MailMerge;
    foreach (Word.MailMergeField f in mailMerge.Fields)
    {
        if (f.Code.Text.IndexOf("MERGEFIELD  \"" + pMergeField + "\"") > -1)
        {
            f.Select();
            app.Selection.TypeText(pValue);
        }
    }
    object saveChanges = Word.WdSaveOptions.wdSaveChanges;
    doc.Close(ref saveChanges, ref missing, ref missing);
    app.Quit(ref missing, ref missing, ref missing);
}

Which I call from my application with the following:

string pWordDoc = @"C:\Users\Pete-Laptop\Documents\CMS Document Mangement\Word Template.dotx";
cDocument.ReplaceMailMergeField(pWordDoc, "fieldAddress1", "Put address here!");

But nothing happens. When I step through the code it gets as far as the app.Documents.Open and then seems to freeze. I believe this is because the application cannot find my Word document. Am I correct in sending the full file path to the filename parameter? If not, how else is the application going to find my Word Template?

The final code I used and which works for me is as follows:

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);
                }
            }
        }
    }

This code is orignally from here.

You could try with:

_doc = _app.Documents.Add(ref _docName , ref _missing , ref _missing , ref _missing );

instead of

_doc = _app.Documents.Open(.......);

and then check if this line is correct:

if (f.Code.Text.IndexOf("MERGEFIELD  \"" + pMergeField + "\"") > -1) 

I have a functioning code that works in this way

        mailMerge = doc.MailMerge;         
        foreach (Word.MailMergeField f in mailMerge.Fields)         
        {    
             // Extract the name of the MergeField starting from the 11 character
             // and looking for the first space after the name 
             // (this means that you avoid MergeFields names with embedded spaces)
             string fieldName = f.Code.Text.Substring(11).Trim();
             int  pos = fieldName.IndexOf(' ');
             if (pos >= 0) fieldName = fieldName.Substring(0, pos).Trim();

             if (fieldName == pMergeField) 
             {
                   f.Select();                  
                   app.Selection.TypeText(pValue);  
             }
