Conditional or in C #

I have been programming in JAVA and C all my years in Uni, but now I am learning C # and building a small application, and I found problems with this:

if (taxonType.Equals(null) ¦¦ taxonID == -1)

I get a red underline for this conditional expression, and I really don’t know why, because according to what I saw, it should be good, but it’s not. Is something missing?

Thank you all in advance, Victor

Thanks everyone !!! I was mad at it. The fact is, I'm Spanish, and I'm used to having a pipe wrench | exactly in the same place where | is in the American configuration ... I saw it is strange, but I thought it was the same ...

Thanks for the quick response!! Victor

Your test for null should not be used .Equals, because if the object is null, an attempt to access the member will call NullReferenceException.

Using:

if (taxonType == null || taxonID == -1)

It is also unclear whether you are using the correct channel symbol |, since your is displayed as ¦.

if (String.IsNullOrEmpty (taxonType) || taxonID <0)

and make a taxon like STRUCT
