UnmanagedType.Bool Field

Bool = 2;

Summary

Specifies a 4-byte Boolean value where true is denoted by all non-zero values and false is denoted by zero.

UnmanagedType.ByValArray Field

ByValArray = 30;

Summary

Specifies an array of fixed size. This unmanaged type is valid only for an array in a structure.

When System.Runtime.InteropServices.MarshalAsAttribute.Value is set to ByValArray , the System.Runtime.InteropServices.MarshalAsAttribute.SizeConst field is required to contain the number of elements in the array.

CustomMarshaler = 44;

Summary

Specifies the custom marshaler class when used with System.Runtime.InteropServices.MarshalAsAttribute.MarshalType or System.Runtime.InteropServices.MarshalAsAttribute.MarshalTypeRef .

UnmanagedType.LPArray Field

LPArray = 42;

Summary

Specifies a C style array. When marshaling from managed to unmanaged, the length of the array is determined by the length of the managed array. When marshaling from unmanaged to managed, the length of the array is determined from the System.Runtime.InteropServices.MarshalAsAttribute.SizeConst and the System.Runtime.InteropServices.MarshalAsAttribute.SizeParamIndex fields.
