c# - Convert FileUpload to X509Certificate2 -


how can convert uploaded file x509certificate2 variable?

i have tried using following code not working:

public bool haspublickey(fileupload file) {     bool check = false;      try     {          x509certificate2 cert = (x509certificate2)file.postedfile.inputstream;     }     catch(exception)     {          check = false;     }  }

if uploaded file valid certificate should have @ constructor or import method in x509certificate2 class.

you'll see need this:

var filelength = file.postedfile.contentlength; var certdata = new byte[filelength];  file.filecontent.read(certdata, 0, filelength);  var cert = new x509certificate2(certdata);

(code not verified it, or similar, should work).
