but findtext function accept only:

findtext(string)
findtext(string, issearchwholeword as boolean)
findtext(string,issearchwholeword as boolean, ignorecase as boolean)

Hello,

Thanks for your feedback.
According to your description, I installed Spire.PDF 6.5.15 and Spire.PDFViewer 5.1.4 from Nuget in a same project, and got the following error, did you encounter the same issue?

Kindly note that the both Spire.PDF and Spire.PDFViewer contain Spire.PDF.dll, and the version of Spire.PDF.dll included in Spire.PDFViewer 5.1.4 is slightly older, it does not yet support the method "FindText("#SIGN#\\d{3}", TextFindParameter.Regex)". For your situation, please install the Spire.Office package (the latest version is Spire.Office 5.5.1) to use them together in the same project.
