Public Property CreationDate As DateTime?
```

### Examples

The following example configures a PDF attachment before embedding it in a WordprocessingML document by using `EmbeddedFile.CreationDate`.

```csharp
EmbeddedFile embeddedFile = new("terms.pdf", @"Attachments\terms.pdf", "application/pdf");

embeddedFile.CreationDate = DateTime.Today;
if (embeddedFile.CreationDate != null)
{
    Console.WriteLine("Embedded File: Creation Date is available.");
}

SaveSettings saveSettings = new() { EmbeddedFiles = new[] { embeddedFile } };
textControl.Save("contract-with-attachment.docx", StreamType.WordprocessingML, saveSettings);
```

```vbnet
Dim embeddedFile As New EmbeddedFile("terms.pdf", "Attachments\terms.pdf", "application/pdf")

embeddedFile.CreationDate = Date.Today
If embeddedFile.CreationDate IsNot Nothing Then
    Console.WriteLine("Embedded File: Creation Date is available.")
End If

Dim saveSettings As New SaveSettings() With { .EmbeddedFiles = New EmbeddedFile() { embeddedFile } }
textControl.Save("contract-with-attachment.docx", StreamType.WordprocessingML, saveSettings)
```
