C# array pass in function like C++?

Is there any way can C# pass an array in function like C++?

In C++, we can pass the array plus offset and length very neat like below

void myFunction(int A[], int m) // m is length of A
{
    myFunction2(A+1, m - 1); 
}

Can C# do it too?

In C# you aren't passing in the pointer to the array, you're passing in an array reference. 

void myFunction(int[] array, int offset)
{
    myFunction(array, offset + 1);
}

This will effectively do the same thing. It's important to know that the length is unnecessary because the array itself is an object reference which carries around the length of the array. So your real length relative to your example can be obtained via array.Length - offset

Sure. However you can't modify pointers, so you would need to pass the offset separately. Also, you don't need to pass around the length, because all C# Arrays have a .Length property to get the array size.

void MyFunction(int[] A, int offset)
{
    MyFunction2(A, offset + 1);
}
