Possible unintended reference comparison

Question

I have the following code which gives a warning

Possible unintended reference comparison; to get a value comparison, cast the left hand side to type \

Answer 1

I prefer to stick the string.Equals(string,string,StringComparison) method, like the following:

    string contentStr = (lblStatus.Content ?? string.Empty).ToString();
    if (string.Equals("ACTIVE", contentStr, StringComparison.OrdinalIgnoreCase))
    { 
        // stuff
    } 

because it explicitely states what it does + it doesn't give a warning you've mentioned.
