C # Equivalent ifstream / ofstream in C ++

Question

I know that this was probably asked earlier, but I can’t find it here anywhere, and I can’t get a clear answer to everything I’m looking for on Google.

I need to know the C # equivalent for C ++ ifstream / ofstream.

For example, if I had the following C ++ code:

ifstream input("myFile.txt");
ofstream output;
output.open("out.txt");

What is the C # equivalent?

I found a site that said (for part of the file anyway) that the equivalent was as follows:

using System.IO;

FileStream fs = new FileStream("data.txt", FileMode.Open, FileAccess.Read);

I tried to include this:

FileStream fs = new FileStream(input, FileAccess.Read);

I do not have “FileMode” in mine, because VS did not recognize it. And "input" is a string in the parameters that contains the string value of the input file name (for example, "myFile.txt").

I know that I need to miss something stupid and insignificant, but I can not understand what it is. Any help on this would be greatly appreciated!

, StreamReader/StreamWriter ++ ifstream/ofstream. FileStream [], StreamReader/StreamWriter .

var writer = new StreamWriter(File.OpenWrite("myFile.txt");
writer.WriteLine("testing");
writer.Close();
var reader = new StreamReader(File.OpenRead("myFile.txt");
while ( !reader.EndOfStream )
{
    var line = reader.ReadLine();
}
