How to remove columns based on names in a list

Question

I have a dataframe as follows where the top is the column name and each column only has one value:

     Sample122       df122      gd412     AKM     532      d21h_7
         32            4           12       25      2         55

I also have a dataframe as follows

       ID             CN
    Sample22          2
     AKM              1
     532              0

I would like to remove the columns in the dataframe based on the list I have. How can I do this?

You could try

df1[setdiff(names(df1),df2$ID)]
