这边我是使用字符数组data先读取二进制文件，
using (var reader = new BinaryReader(File.OpenRead(filename)))
{
reader.BaseStream.Seek(0, SeekOrigin.Begin);
reader.Read(data, 0, 40);
}
//data 数组赋值给结构体
int _StuctSize = Marshal.SizeOf(typeof(netBaseParamStructure));
Console.WriteLine(_StuctSize);
IntPtr _StructIntPtr = Marshal.AllocHGlobal(_StuctSize);
Marshal.Copy(data, 0, _StructIntPtr, _StuctSize);
object _StructObject = Marshal.PtrToStructure(_StructIntPtr, typeof(netBaseParamStructure));
Marshal.FreeHGlobal(_StructIntPtr);
netBaseParamStructure _Image = (netBaseParamStructure)_StructObject
我想请问如何不通过字符数组直接用结构体接受二进制文件的内容？？？？？
