In our daily work, we may have the requirement to add custom properties with fields to a Word document. As is shown in the following Word document, I have created three custom property fields for easily inserting or updating information.
However, a custom property field may lose its value if we don’t want to use it any more, or a custom field might be created with wrong information, in such cases, we can choose to delete these fields manually and programmatically. In this article, I’ll introduce a C# and VB.NET solution to remove custom property fields using Spire.Doc.
Detailed Steps
Step 1: Create a new instance of Spire.Doc.Document class and load the sample file with specified path.
Document doc = new Document();
doc.LoadFromFile("FieldSample.docx", FileFormat.Docx);
Step 2: Get custom document properties object.
CustomDocumentProperties cdp = doc.CustomDocumentProperties;
Step 3: Use a for sentence and CustomDocumentProperties.Remove(string name) method to remove all custom property fields in the document.
for (int i = 0; i < cdp.Count; )
{
cdp.Remove(cdp[i].Name);
}
doc.IsUpdateFields = true;
Step 4: Save the file.
doc.SaveToFile("Result.docx", FileFormat.Docx);
Output:
Full Code:
using Spire.Doc;
namespace RemoveProperties
{
class Program
{
static void Main(string[] args)
{
Document doc = new Document();
doc.LoadFromFile("FieldSample.docx", FileFormat.Docx);
CustomDocumentProperties cdp = doc.CustomDocumentProperties;
for (int i = 0; i < cdp.Count; )
{
cdp.Remove(cdp[i].Name);
}
doc.IsUpdateFields = true;
doc.SaveToFile("Result.docx", FileFormat.Docx);
}
}
}
Imports Spire.Doc
Namespace RemoveProperties
Class Program
Private Shared Sub Main(args As String())
Dim doc As New Document()
doc.LoadFromFile("FieldSample.docx", FileFormat.Docx)
Dim cdp As CustomDocumentProperties = doc.CustomDocumentProperties
Dim i As Integer = 0
While i < cdp.Count
cdp.Remove(cdp(i).Name)
End While
doc.IsUpdateFields = True
doc.SaveToFile("Result.docx", FileFormat.Docx)
End Sub
End Class
End Namespace
