Closing the StreamReader

Question

Is there any Using.System command or anything else, to close the automatically StreamReader.

I've been closing the StreamReader like this e.g.:

sr.Close();

Do you mean `using(var sr = GetMyStreamReader()){ /* ... */}`? — JohnLBevan, May 25 '18 at 17:34
In any case, if this is .NET, if a class implements IDisposable, always create it in a `using` block: `using (var x = new StreamReader(param)) { ... }`. That takes care of closing it. — 15ee8f99-57ff-4f92-890c-b56153, May 25 '18 at 17:34

If you implement a using statement the streamreader will be disposed automatically.

using (StreamReader r = new StreamReader("file.txt"))
{
  allFileText = r.ReadToEnd();
}

Since OP is so new, it might be worth mentioning that "dispose" can be presumed to include `Close()`. I recently spotted some old production code where a relatively experienced developer, years ago, assumed otherwise. – 15ee8f99-57ff-4f92-890c-b56153 May 25 '18 at 17:39
