How to read/write files in .Net Core?

What are the options to read/write files in .Net Core?

I am working on my first .Net Core app and looking for File.Read*/File.Write* functions (System.IO from .Net) alternatives.

Package: System.IO.FileSystem

System.IO.File.ReadAllText("MyTextFile.txt"); ?

FileStream fileStream = new FileStream("file.txt", FileMode.Open);
using (StreamReader reader = new StreamReader(fileStream))
{
    string line = reader.ReadLine();
}

Using the System.IO.FileStream and System.IO.StreamReader. You can use System.IO.BinaryReader or System.IO.BinaryWriter as well.

To write:

using (System.IO.StreamWriter file =
new System.IO.StreamWriter(System.IO.File.Create(filePath).Dispose()))
{
    file.WriteLine("your text here");
}

Works in Net Core 2.1

    var file = Path.Combine(Directory.GetCurrentDirectory(), "wwwroot", "email", "EmailRegister.htm");

    string SendData = System.IO.File.ReadAllText(file);

Use:

File.ReadAllLines("My textfile.txt");
