Use the debugger, and check the value of Rptpwd - the chances are it doesn't contain any string, or an invalid Base64 string. THen, I'm afraid, it's up to you to work out why - we can't see your screen, access your HDD, or read your mind! :laugh:

The null-coalescing operator (??) was added in C# 8, which was released 5½ years after this already-solved question was asked.

Solution 1

Obviously Rptpwd should not be null and you should have set it with a value earlier, but to avoid the exception you can do :

C#

if(Rptpwd!=null)
    byteBuff = Convert.FromBase64String(Rptpwd);
