How to check if all parameters a set

Question

hello i have a little problem with my project.

My project gets from the user an array with 5 places these are also parameters for a key that I generate. now I want to check before the key is generated if the user has also set all 5 parameters (array entries) and if not it should come in error. how can I do this? sorry for my bad english

For example, in case of strings, you can use Any:

string[] parameters = new string[5];

// . . .

if( parameters.Any(string.IsNullOrWhiteSpace))
{
    // ERROR; some values are not provided
    . . . .                     
}

Show details if your parameters are different.
