C# Struct No Parameterless Constructor? See what I need to accomplish
c#, constructor, dll, dllimport, struct
Solution
You can use a fixed size buffer - which I suspect you really want anyway, so as to get the data "inline" in the struct (rather than a reference to an array elsewhere).
public fixed byte name[24];
You'll need to declare the struct as unsafe as well though.
Note that any "solution" which requires calling a static method or providing any kind of custom constructor will fail with your explicit goal of being able to create an array of these structs.
Problem
I am using a struct to pass to an unmanaged DLL as so - ``` [StructLayout(LayoutKind.Sequential)] public struct valTable { public byte type; public byte map; public byte spare1; public byte spare2; public int par; public int min; public byte[] name; public valTable() { name = new byte[24]; } } ``` The code above will not compile because VS 2005 will complain that "Structs cannot contain explicit parameterless constructors". In order to pass this struct to my DLL, I have to pass an array of struct's like so `valTable[] val = new valTable[281];` What I would like to do is when I say `new`, the constructor is called and it creates an array of bytes like I am trying to demonstrate because the DLL is looking for that byte array of size 24 in each dimension. How can I accomplish this?
