c# - How to ensure localculture is used for interface but not floating point values in WinForms? -

-



i have winforms application on russian system. number of reasons, prefer using floating-values formatting invariantculture (which english).

following found solutions in internet, have set invariantculture default culture application. however, result, localised versions of forms (with russian text) never loaded.

how can ensure forms russian text automatically loaded on russian machines, floating point values string conversions invariantculture behaviour used?

you can alter property of cultureinfo after creating specific culture, e.g.:

// create culture default values russian var culture = new cultureinfo("ru-ru"); // change number format culture.numberformat = new numberformatinfo { numberdecimalseparator = "." }; // set culture thread.currentthread.currentculture = thread.currentthread.currentuiculture = culture;

after don't need specify culture parsing/formatting:

var test = double.parse("1.234"); // throw without changing numberformat messagebox.show(test.tostring()); // output: 1.234

python - Read npy file directly from S3 StreamingBody -

i have many .npy (numpy) , .json files saved in s3, need download , load these files. for json files downloading files , loading dictionary using following code: obj = s3.object(bucket, key) response = obj.get() body = response['body'].read().decode('utf-8') data = json.loads(body) that way avoid writing .json file disk , reading it. now want same .npy files, equivalent? currently downloading file, saving temp file on disk , loading np.load avoid if possible. following https://stackoverflow.com/a/28196540/3509999 : obj = s3.object(bucket, key) io.bytesio(obj.get()["body"].read()) f: # rewind file f.seek(0) arr = np.load(f) wiki
