Advanced search for Form Field signatures Leave feedback

GroupDocs.Signature provides FormFieldSearchOptions class to specify different options to search for Form Field Signatures.

Here are the steps to search for Form Field signatures within the document with GroupDocs.Signature:

• Create new instance of Signature class and pass source document path as a constructor parameter.
• Instantiate the FormFieldSearchOptions object according to your requirements and specify search options
• Call Search method of Signature class instance and pass FormFieldSearchOptions to it.

This example shows how to make advanced search for Form Field signatures in the document.

using (Signature signature = new Signature("signed.pdf"))
{
    FormFieldSearchOptions options = new FormFieldSearchOptions()
    {
        Value = "Value1",
        AllPages = true,
        Name = "TestField",
        Type = FormFieldType.Text
    };
    // search for signatures in document
    List<FormFieldSignature> signatures = signature.Search<FormFieldSignature>(options);
    Console.WriteLine("\nSource document contains following signatures.");
    foreach (var formFieldSignature in signatures)
    {
        Console.WriteLine("FormField signature found. Name : {0}. Value: {1}", formFieldSignature.Name, formFieldSignature.Value);
    }
}
