C# save Hyperlink to Excel File does not work correctly

Question

I´m create a file where its possible to add a link to a specific website. So far thats possible but the Link shows a path in my C drive and then the content of the textbox with the real link like: C:\ProgramData\www.google.de.

Why is that see the program for the Link saving in excel:

Microsoft.Office.Interop.Excel.Range excelCell1 = (Microsoft.Office.Interop.Excel.Range)ws.get_Range("C19", "C19");
ws.Hyperlinks.Add(excelCell1, textBox20.Text, Type.Missing, "Click to open", "Click to open"); 

Answer 1

Try prepending the "http://" or "https://". For example, instead of "www.bing.de" use "https://www.bing.de".

If it works manually, maybe this can be done programmatically.
