What exactly do you mean by "convert"? Write the same in C#, or something?

Note that even your C++ code is badly written. Why the immediate constant 6 is used (hard-coded)? Why don't you pass the length? What if the number of elements in the array is less? Besides, for i=0, your code will crash because the index will be out of range (-1). No, this is not a valid code.

In C#, it could be something like:

C#

class CmsTest {
    
    static void FirstTest(byte[] data) {
        for (int index = 0; index < data.Length; ++index) {
            // do something correct with data, data[index],
            // not what is written in your invalid C++ code
        }
    }
 
}

Good luck,
