C# Type conversion when using CreateDIBSection -


first, please read link

to using createdibsection in c#, defined this.

[dllimport("gdi32.dll", entrypoint = "createdibsection")] public static extern intptr createdibsection(intptr hdc, ref bitmapinfo pbmi,                      uint iusage, out intptr ppvbits, intptr hsection, uint dwoffset);

and defined structure type learned link this

public unsafe struct my_binfo {     [marshalas(unmanagedtype.u4)]     public fixed uint bmicolors[3];  }

a problem related mybitmapinfo defined.

[structlayout(layoutkind.sequential)] public unsafe struct mybitmapinfo  {    public bitmapinfoheader bmiheader;     [marshalas(unmanagedtype.u4)]    public fixed uint bmicolors[3];  }

when call createdibsection function, mybitmapinfo converted bitmapinfo type [link_1]

createdibsection(hdc, (const bitmapinfo* )&dibinfo, ... ) //c++ code

however dont't know how write c# code same thing above code.(type conversion mybitmapinfo bitmapinfo)

thank reading.
