File stream Speed Question

alright so i want to make a program that takes all of the c# files in a directory, copies all of their content to that single file and trim the using statements

note i haven't used filestream in c# before anyways i want to which method would be faster for copying the content: - copying all of the lines in one file to a single array/List, and doing that for each .cs file in the directory, or - directly copying each line from the original file to the output file while i'm iterating through each file i would assume the latter would be faster or both methods would be the same speed

That's one weird thing you're trying to do there, gotta say

The FatherOP•4mo ago

it's for school since i can't run .net or anything on the chromebooks and i want to use an online compiler

If I were to do concatenating files, I'd probably loop over them, read each individually, and keep appending them to a file

The FatherOP•4mo ago

so read a line, append it to the file and repeat for each line of each file?

Angius•4mo ago

No Read a file, append it to the end

The FatherOP•4mo ago

mm so you can just copy the content of the whole file?

Angius•4mo ago

Sure

The FatherOP•4mo ago

mm alright thanks

Also, you can install VS Code on a Chromebook, just gotta enable Linux layer Alternatively, Github has free codespaces

The FatherOP•4mo ago

linux is blocked what is a codespace

Angius•4mo ago

A remote virtual machine with VS Code running in the browser connected to it

The FatherOP•4mo ago

oh fuck yeah it seems like it might work so it would work with VS solutions then?

Angius•4mo ago

Alternatively, take it up with your school. If they require you to write good and proper C# on a Chromebook, they better make it work for you Well, depends Is it .NET Framework or .NET? If the former, it's Windows-only

The FatherOP•4mo ago

.NET i'm sure yeah

Angius•4mo ago

If the latter, then yes

The FatherOP•4mo ago

i don't even know the difference other than that .net framework is windows only i'm doing c# for fun but i wish i knew how to do that @ZZZZZZZZZZZZZZZZZZZZZZZZZ also is it possible for a using statement to have a string in it

Angius•4mo ago

Wym?

The FatherOP•4mo ago

it likely won't be a problem but just in case using "this thing" if not then i only have to parse it with consideration for comments since the symbols can't have backslashes

Angius•4mo ago

That's not valid C#

The FatherOP•4mo ago

ok good

Angius•4mo ago

using System.Text.Json; // namespace import
using static System.Console; // static class import
using Foo = (int a, int b); // type alias

using var d = SomethingDisposable(); // using disposables
using (var d = SomethingDisposable()) // another way
{
    // ...
}

using System.Text.Json; // namespace import
using static System.Console; // static class import
using Foo = (int a, int b); // type alias

using var d = SomethingDisposable(); // using disposables
using (var d = SomethingDisposable()) // another way
{
    // ...
}

all the valid situations where using works

The FatherOP•4mo ago

alright thanks wait so what would you use this for

using var d = SomethingDisposable();

using var d = SomethingDisposable();

and would this free d immediately after exiting the scope?

using (var d = SomethingDisposable()) // another way
{
    // ...
}

using (var d = SomethingDisposable()) // another way
{
    // ...
}

that would explain why you use it for filestream

Angius•4mo ago

With the using statement, the resource is freed at the end of the scope With the using block, at the end of the block

The FatherOP•4mo ago

alright thanks
