Question

is it possible to somehow cast the type of a pointer created by the fixed() statement?

This is the situation:

I have an array of byte, which i would like to iterate through, however i would like the values to be treated as int, thus having an int* instead of a byte*.

Here’s some exemplary code:

byte[] rawdata = new byte[1024];

fixed(int* ptr = rawdata) //this fails with an implicit cast error
{
    for(int i = idx; i < rawdata.Length; i++)
    {
        //do some work here
    }
}

Can this be done without having to do the cast inside the iteration?

Answer 1

byte[] rawdata = new byte[1024];

fixed(byte* bptr = rawdata)
{
    int* ptr=(int*)bptr;
    for(int i = idx; i < rawdata.Length; i++)
    {
        //do some work here
    }
}
