Passing an array of strings

[kliz0328]

We have a C# wrapper and are currently passing values as sbyte[], I was wondering how to pass strings instead of bytes? Below is some sample code that outlined hot to pass sbyte[], is there anyway to pass it as string?

[MarshalAs(UnmanagedType.ByValArray, SizeConst=7*80)]
		public sbyte[] AHScheduleType;
		[MarshalAs(UnmanagedType.ByValArray, SizeConst=7*80)]
		public sbyte[] InsPlanType;
		[MarshalAs(UnmanagedType.ByValArray, SizeConst=4*80)]
		public sbyte[] InsType;
		[MarshalAs(UnmanagedType.ByValArray, SizeConst=24*80)]
		public sbyte[] AvailablePaymentFrequencyName;
		[MarshalAs(UnmanagedType.ByValArray, SizeConst=24*80)]
		public sbyte[] AvailablePaymentFrequencyCode;
		[MarshalAs(UnmanagedType.ByValArray, SizeConst=24*80)]
		public sbyte[] AvailableLoanTypeName;
		[MarshalAs(UnmanagedType.ByValArray, SizeConst=24*80)]
		public sbyte[] AvailableLoanTypeCode;
		[MarshalAs(UnmanagedType.ByValArray, SizeConst=10*5*80)]
		public sbyte[] AvailableSolveType;
		[MarshalAs(UnmanagedType.ByValArray, SizeConst=10*5*80)]
		public sbyte[] AvailableSolveCode;
		[MarshalAs(UnmanagedType.ByValArray, SizeConst=24*80)]
		public sbyte[] DPName;
		[MarshalAs(UnmanagedType.ByValArray, SizeConst=24*80)]
		public sbyte[] DPDescription;
		[MarshalAs(UnmanagedType.ByValArray, SizeConst=24*80)]
		public sbyte[] DPCode;
