How to: Obtain a Pointer to Byte Array

You can obtain a pointer to the array block in a xref:System.Byte array by taking the address of the first element and assigning it to a pointer.

Example

// pointer_to_Byte_array.cpp// compile with: /clrusingnamespaceSystem;intmain() { Byte bArr[] = {1, 2, 3}; Byte* pbArr = &bArr[0]; array<Byte> ^ bArr2 = gcnew array<Byte>{1,2,3}; interior_ptr<Byte> pbArr2 = &bArr2[0]; }
