Return ValueType: System.IntPtr
The offset, in bytes, for the fieldName parameter within the specified class that is declared by platform invoke.
provides the offset in terms of the unmanaged structure layout, which does not necessarily correspond to the offset of the managed structure layout. Marshaling the structure can transform the layout and alter the offset. The t parameter can be a value type or a formatted reference type (with either a sequential or explicit layout). You can obtain the size of the entire layout by using the Marshal.SizeOf method. For additional information, see Default Marshaling for Value Types.
