This website is using a safety provider to protect by itself from online assaults. The action you merely performed triggered the safety Option. There are plenty of actions that could set off this block which include submitting a specific term or phrase, a SQL command or malformed data.
That assignment throws an ArgumentException. Because a property set accessor must have a void return kind, you report glitches during the set accessor by throwing an exception.
It might toss a NullReferenceException with out this check in that case. To find out more, see activities. This instance also employs The brand new nameof operator to transform in the home identify image to its textual content representation.
