how to do vb.net replace on a byte array

Question

User1682543174 posted

I have a byte array of data. How can I find and replacement a part of the byte array with replacement data?

dim foo as byte foo = MY DATA

If foo was a string, then I would do: foo = replace( foo, target, replacement )

But foo is a byte array. How can I replace?

You can just loop through the elements of the array and reset the values of the ones you want to change:

For i = 0 To foo.Length - 1
    If foo(i) = some_value_you_want_to_change Then foo(i) = replacement_value
Next

This cannot work.  There's a different # of replacement bytes.

Yes it can. But not for your current requirement, whatever that is.
