Layout of .NET value type in memory

Question

I have the following .NET value types:

[StructLayout(LayoutKind.Sequential)]
public struct Date
{
    public UInt16 V;
}

[StructLayout(LayoutKind.Sequential         


        

Answer 1

Two things:

• StructLayout(Sequential) does not guarantee packing. You might want to use Pack=1, otherwise 32 and 64bit platforms might be different.

• and string is a reference, not a pointer. If the string length is always fixed, you might want to use fixed char arrays:

  public struct MyArray // This code must appear in an unsafe block
  {
      public fixed char pathName[128];
  }
