Check document password-protection

GroupDocs.Merger allows to check document for password-protection. The result will be true if document has password for opening set, in other case false will be returned.

Here are the steps to check document password-protection:

• Instantiate Merger object with source document path or stream;
• Call IsPasswordSet method.

The following code sample demonstrates how to check document password-protection.

bool isPasswordSet = false;
string filePath = @"C:\sample.xlsx";

using (Merger merger = new Merger(filePath))
{
	isPasswordSet = merger.IsPasswordSet();
}
