What is the equivalent of memset in C#?
- by Jedidja
I need to fill a byte[] with a single non-zero value. How can I do this in C# without looping through each byte in the array?
Update: The comments seem to have split this into two questions -
Is there a Framework method to fill a byte[] that might be akin to memset
What is the most efficient way to do it when we are dealing with a very large array?
I totally agree that using a simple loop works just fine, as Eric and others have pointed out. The point of the question was to see if I could learn something new about C# :) I think Juliet's method for a Parallel operation should be even faster than a simple loop.

It turns out the simple for loop is the way to go unless you want to use unsafe code.
Apologies for not being clearer in my original post. Eric and Mark are both correct in their comments; need to have more focused questions for sure. Thanks for everyone's suggestions and responses.
