You you familiar with P/Invoke in general? Is this C++ or C++/CLI?

this is C++
want to write a same version in C#,without using P/invoke

why just don't you make a class instead of this struct in c#?

You should use native string type instead of stl string:
In C++ it will be looks:

C++

struct node
{
    int x;
    char y[256];
};

And in C# it will be wrapped

C#

[StructLayout(LayoutKind.Sequential,CharSet=CharSet.Ansi)]
public struct node
{
    public int x;
    [MarshalAs(UnmanagedType.ByValTStr,SizeConst=256)]
    public string y;
};

For Unicode you should change type char to wchar_t in C++ structure and CharSet attribute value in C# structure.

Solution 3

It's more or less the same in C#, see the documentation[^].
