将二进制数据直接写入结构体的C#/ .net等价物是什么？

using System;
using System.IO;

public struct MyStruct
{
    public int IntValue;
    public float FloatValue;
    public string StringValue;
}

public class Program
{
    public static void Main()
    {
        MyStruct myStruct;
        myStruct.IntValue = 123;
        myStruct.FloatValue = 456.789f;
        myStruct.StringValue = "Hello, World!";

        using (MemoryStream memoryStream = new MemoryStream())
        {
            using (BinaryWriter binaryWriter = new BinaryWriter(memoryStream))
            {
                binaryWriter.Write(myStruct.IntValue);
                binaryWriter.Write(myStruct.FloatValue);
                binaryWriter.Write(myStruct.StringValue);
            }

            memoryStream.Position = 0;

            using (BinaryReader binaryReader = new BinaryReader(memoryStream))
            {
                myStruct.IntValue = binaryReader.ReadInt32();
                myStruct.FloatValue = binaryReader.ReadSingle();
                myStruct.StringValue = binaryReader.ReadString();
            }
        }

        Console.WriteLine($"IntValue: {myStruct.IntValue}");
        Console.WriteLine($"FloatValue: {myStruct.FloatValue}");
        Console.WriteLine($"StringValue: {myStruct.StringValue}");
    }
}
