How to clear byte array?

Is there any elegant way to empty an array in c#? I noticed that in the past there was a .clear method, but now notihing like that exists. (The only way to empty an array I found out is to create new variable which is empty and assign it ot the old one (and hope the old one will be garbage collected))

Thank you!

Lists have .Clear() methods, but Arrays do not. You need to overwrite each single value if you want to reset the array. Your way of assigning a newly created array is just fine; also, most of the time there is no need at all to have the array initialized in the first place!

You can replace the old array by an empty array:

// initialize array:
string[] myArray = new string[]{"Hello", "World!"}:

// 'clear' array:
myArray = new string[0];  // the old instance will be deleted by the garbage collection
