Fields update

[zhongming]

I have a template word document which contains some DOCVARIABLE,

I want to update those VARIABLE with new Text, like updating [Company] to ‘HP’, ‘IBM’, updating NAME to ‘Tom’, ‘Jack’, programmatically of course

Now I have successfully retrieve those DOCVARIABLE like below in c#:

Document doc = new Document("a doc");
NodeCollection fieldStarts = doc.GetChildNodes(NodeType.FieldStart, true, false);
foreach(FieldStart fieldStart in fieldStarts)
{
    if (fieldStart.FieldType.Equals(FieldType.FieldDocVariable))
    {
        // how to upate these fields?
    }
}

How do I update these fields?

Hello

Thanks for your request. In this case you should use the following code:

Document doc = new Document("in.doc");
doc.Variables["VariableName"] = "VariableValue";
// We need to update fields before saving
doc.UpdateFields();
doc.Save("out.doc");

Best regards,

Thanks for the reply!
It is not working.
I checked the doc.Variables.Count, it is 0, I actually have 13 variables there.

Hello

Thank you for additional information. I cannot reproduce the problem on my side using the latest version of Aspose.Words (9.4.0). I use the following code for testing:

Document doc = new Document("test.doc");
doc.Variables["UserName"] = "Andrey";
doc.Variables["UserCompany"] = "Aspose";
doc.Variables["UserAddress"] = "Address";
// We need to update fields before saving
doc.UpdateFields();
doc.Save("out.doc");

You can download the latest version from here:
https://releases.aspose.com/words/net
Please see the attached document produced on my side.

Sorry, I checked the wrong output path, the code you provided actually works!
But the interesting thing is that variable.count is always 0.: (

Hello

Thank you for additional information. If you will try getting variables count from out.doc (from my previous post), you will get the count 3.

Document doc = new Document("out.doc");
Console.WriteLine(doc.Variables.Count);

{DOCVARIABLE Name * MERGEFORMAT} is just “link” to the appropriate variable. Variable appears inside a document only after initialization.
Best regards,
