Syncfusion Essential PDF is the .NET PDF library used to create, read, and edit PDF documents. Using this library, you can load the corrupted PDF documents by using the OpenAndRepair parameter from the PdfLoadedDocument instance.

Steps to load the corrupted PDF file programmatically:

1. Create a new C# console application project.
2. Install the Syncfusion.Pdf.WinForms NuGet package as reference to your .NET Framework applications from NuGet.org.
3. Include the following namespaces in the Program.cs file.

C#

4. Use the following C# or VB.NET code snippet to remove the XMP metadata from the PDF document.

C#

//Load the corrupted document and set true to repair the document
PdfLoadedDocument ldoc = new PdfLoadedDocument("input.pdf", true);
 
//Save the document
ldoc.Save("Output.pdf");
 
//Close the document
ldoc.Close(true);

VB.NET

'Load the corrupted document and set true to repair the document
Dim ldoc As New PdfLoadedDocument("input.pdf", True)
 
'Save the document
ldoc.Save("Output.pdf")
 
'Close the document
ldoc.Close(True)
