如何将二进制文件加载到结构中并获取数据
本文关键字:获取 数据 结构 二进制文件 加载 | 更新日期: 2023-09-27 18:20:09
我已经完成了在stackoverflow上搜索任何主题来解决我的问题,但我仍然无法用我的代码解决问题我想用c#读取二进制文件,并为其制作一个结构
这是代码
[StructLayout(LayoutKind.Explicit, CharSet = CharSet.Auto)]
public struct YourStruct
{
[FieldOffset(44)]
public int none; // 4 bytes
[FieldOffset(48)]
//[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 156)]
[MarshalAs(UnmanagedType.LPTStr, SizeConst = 156)]
public String alldata;
}
private void button1_Click(object sender, EventArgs e)
{
string strFilePath = @"F:'dat'bintest.bin";
FileStream stream = File.OpenRead(strFilePath);
YourStruct aStruct;
//int count = Marshal.SizeOf(typeof(YourStruct));
int count = 791616;
byte[] readBuffer = new byte[count];
BinaryReader reader = new BinaryReader(stream);
readBuffer = reader.ReadBytes(count);
GCHandle handle = GCHandle.Alloc(readBuffer, GCHandleType.Pinned);
aStruct = (YourStruct)Marshal.PtrToStructure(handle.AddrOfPinnedObject(), typeof(YourStruct));
handle.Free();
Console.WriteLine("None = {0}", aStruct.none);
Console.WriteLine("Data : {0}", aStruct.alldata);
}
问题是,当我运行这个项目时,aStruct.alldata什么都没有显示,就像没有读取文件一样
有什么解决方案吗?谢谢
更改
[MarshalAs(UnmanagedType.LPTStr, SizeConst = 156)]
至
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 156)]
