Code Inspection: Specify string culture explicitly
Ad-hoc conversion of data structures to text is largely dependent on the current culture, and may lead to unintended results when the code is executed on a machine whose locale differs from that of the original developer. To prevent ambiguities, JetBrains Rider warns you of any instances in code where such a problem may occur.
For example, take the following code
int x; // some statements DoSomething(x.ToString());
While one might think that an
int is culture-invariant, this is in fact not the case: for example, in this case, the negative sign that gets rendered if the value is negative can be different depending on culture (this value can also be customized via the Region and Language settings in Windows). As a result, it often makes sense to specify either a specific culture (e.g., the
Thread.CurrentThread.CurrentCulture) or an invariant culture (
CultureInfo.InvariantCulture) for string conversions.
